This talk explores the pivotal role of map data localization, focusing on the inspiring context of OSM Nepal, and introducing OSMLocalizer as a game-changing solution.\r\n\r\nLocalization breathes life into maps, making them relatable and accessible to diverse communities. At the heart of this concept lies OSM Nepal's campaign to localize place names, which exemplifies the essence of this endeavor. However, the process posed challenges as there were no dedicated tools specifically designed for map data localization. Contributors had to rely on existing tools like MapRoulette, causing inefficiency as they had to juggle multiple tabs between editing tools, Project Management, and translation engines. Here, OSMLocalizer emerges as the beacon of efficiency and integration.\r\n\r\nOSMLocalizer's approach is simple yet revolutionary. With a built-in editor, contributors can seamlessly edit and localize map features within the same interface, eliminating the need to switch tabs. Further streamlining the process, OSMLocalizer integrates translation engine APIs, making translations accessible within the tool. This holistic approach transforms map data localization from a tedious chore to an engaging and intuitive experience.\r\n\r\nThe context of OSM Nepal accentuates the relevance of such a tool. As contributors passionately pursued localized place names, OSMLocalizer bridged the gap between editing, translation, and seamless contributions. This talk will present OSMLocalizer as a catalyst for efficient and community-centered map data localization.\r\n\r\nIn a world where maps connect people and places, this presentation delves into the heart of map data localization and its profound impact.

Drones are being used to detect distressed vessels quickly in the open ocean. The current system does not have a plan to operate drones according to the search target, which means it is inefficiently operated and the search time is delayed, reducing the chance of survival. The operation plan should be developed based on tests in various environments and conditions. However, real-world implementations of distress situations have limitations. In the real world, implementing human distress in the ocean is limited by safety issues.\r\nIn order to find the optimal way to operate the drone for marine search and rescue, this study aims to construct a simulation environment with various environments and conditions.\r\nTo realize the simulation environment, Unity Engine was used. The environmental aspects of the simulation include the sea (sea colour, wave height), objects (vessels, people, etc.), and the environment (day, night, sunny, rain, snow, fog, etc.). In terms of functionality, camera angles can be set, and adding a drone function allows the drone to move and shoot. In this paper, the environment factor was fixed to daytime clear weather, and the focus was on the object to be searched. The simulation was developed with five types of distress vessels (2-tonne fishing vessel, 5-tonne fishing vessel, cargo vessel, passenger vessel, and motorboat) and six types of distressed persons (baby, adult, and with or without life jackets). The distress vessels can be set to sink, capsize, or drift, and the distress persons are drifting on the surface of the water. The altitude of the drone was limited to a maximum of 150m to comply with Korean law, and the camera angle could be set to (-30\ufe12, -45\ufe12, -60\ufe12, -90\ufe12). To reflect real-world coordinates, Cesium was integrated into Unity to simulate a marine environment. To do this, Cesium's coordinate system was adapted to be compatible with Unity's coordinate system, and the positions of the distressed person and the marine police in the distress scenario were expressed in terms of actual Earth longitude, latitude, and height. This maintains the scale and realism of the simulation environment.\r\nIt is expected that future simulation results will be used to develop a drone operation plan to effectively search for various distress ships and distressed person to minimize human casualties.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "LRNF8N", "name": "Jeonghyo Oh", "avatar": "https://talks.staging.osgeo.org/media/avatars/Jeonghyo_Oh_u7cAiOc.jpg", "biography": "I am studying Geospatial Information Engineering at the University of Seoul.", "public_name": "Jeonghyo Oh", "guid": "f718cf10-07d8-5d7d-a5a6-89ad22c62cb6", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/LRNF8N/"}, {"code": "DDB77E", "name": "Lee Juhee", "avatar": null, "biography": null, "public_name": "Lee Juhee", "guid": "45e53fe5-0516-5533-84d5-c661336a80dc", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/DDB77E/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/WFDPAG/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/WFDPAG/", "attachments": []}, {"guid": "d59c7a57-1e0a-5915-93bc-f98f6aa4a55a", "code": "JNEYZ9", "id": 1656, "logo": null, "date": "2023-11-29T17:00:00+09:00", "start": "17:00", "duration": "00:10", "room": "Seoul Archive", "slug": "foss4g-asia-2023-1656-expanding-the-use-of-foss4g-through-qgis-workshops", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/JNEYZ9/", "title": "Expanding the use of FOSS4G through QGIS workshops", "subtitle": "", "track": "General Track(Talks, Online Talks, Lightning Talks, Workshops)", "type": "Lightning Talk", "language": "en", "abstract": "It is often difficult to expand the use of FOSS4G softwares and business solutions due to lack of promotional materials and introductory resources.

Consequently, many organizations have adopted the STAC specification as a standard for implementing and providing their data in STAC format. As a means for spatial temporal asset indexing, STAC is presented in JSON or GeoJSON formats, enabling interoperability with various services and facilitating comprehension for both machines and humans. STAC is not constrained to specific types of geospatial data; it can be utilized to catalog a diverse range of assets, from satellite imagery to environmental datasets. Through a well-designed structure, it can be integrated into various applications, allowing organizations to harness existing datasets for diverse purposes. STAC also possesses the capability to search for metadata describing assets based on time and location, rendering spatial temporal assets easily discoverable and accessible. \r\n\r\nIn Thailand, STAC is applied in various scenarios, including the GISTDA Decision Support System for Disaster Management Platform. In the platform, STAC catalogs vector data related to flooding areas, thermal activities, and drought indices. Therefore the implemented application can efficiently browse and retrieve data from the STAC catalog, enhancing data retrieval speed and user experience.

Unlike commercial-grade resources, open-source resources are free, customizable, and subject to the larger community of developers for fixing vulnerabilities. This has emphasized the need to utilize technology and freely available resources to create structured and effective systems for managing utilities. Utilities such as electricity, water, sewer, drainage, and infrastructures like cable lines, supply pipelines, roads, and others have become integral to modern life.

MilMap is a military geo-portal system widely and successfully used in every sectors of Korean military. The system is now undergoing major upgrade from geo-portal to military digital twin system. \r\n\r\nMilMap is developed on top of numerous open source projects such as PostGIS, GeoServer, GeoWebCache, Cesium, OpenLayers, mago3D, OpenGXT. The system provides several functionalities like POI search, geospatial data search, layer control, satellite image search and download, spatial terrain analysis, coordinates reading, and map notes, to the military officers through the intranet. Although the system provides geospatial analytics functions through OGC WPS(Web Processing Service), the current system is basically a web based 3D GIS for data viewing and printing. Thanks to MilMap, military officers can now access the huge amount of geospatial data(maps, imagery, 3D, POI, and others) in their browser without installing additional software. \r\n\r\nMilMap is now undergoing major development to be a more customized, automated, and analytical system. The future MilMap will support user data uploading for intelligence sharing, more bespoke battle field analysis and others. In the long run, MilMap is expected to be a cloud based military digital twin system for geospatial intelligence sharing and battle field analysis & simulation.\r\n\r\nThis research is financially supported by the Institute of Civil Military Technology Cooperation funded by the Defense Acquisition Program Administration and Ministry of Trade, Industry and Energy of Korean government under grant No. UM22402RD4.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "Z8DMDB", "name": "Sanghee Shin", "avatar": "https://talks.staging.osgeo.org/media/avatars/Sanghee_2_yZmun7d.jpg", "biography": "CEO & President of Gaia3D, Inc. \r\nFormer OSGeo Board of Directors\r\nOSGeo Charter Member", "public_name": "Sanghee Shin", "guid": "d40d518d-19df-5886-abf5-fa8638f7dd69", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/Z8DMDB/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/E9W9NQ/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/E9W9NQ/", "attachments": []}, {"guid": "7f4795b7-ed88-55db-90cd-fdbf7a150344", "code": "TT8A8R", "id": 1956, "logo": null, "date": "2023-11-29T14:45:00+09:00", "start": "14:45", "duration": "00:20", "room": "Baseurak Hall", "slug": "foss4g-asia-2023-1956-un-hybrid-gis-platform-by-timur-obukhov", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/TT8A8R/", "title": "[UN] - Hybrid GIS Platform by Timur Obukhov", "subtitle": "", "track": "General Track(Talks, Online Talks, Lightning Talks, Workshops)", "type": "Talk", "language": "en", "abstract": "A talk for UN Open GIS Joint Workshop", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "D78RGE", "name": "FOSS4G-Asia 2023", "avatar": "https://talks.staging.osgeo.org/media/avatars/foss4g-asia-logo-00_small_QWxX9e3.png", "biography": "FOSS4G-Asia 2023 Seoul LOC", "public_name": "FOSS4G-Asia 2023", "guid": "3db9aecd-0d88-5bb6-8bc3-77a0744466be", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/D78RGE/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/TT8A8R/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/TT8A8R/", "attachments": []}, {"guid": "fa7e6000-6050-5240-a719-a705e8744446", "code": "D3XYHN", "id": 1957, "logo": null, "date": "2023-11-29T16:00:00+09:00", "start": "16:00", "duration": "00:20", "room": "Baseurak Hall", "slug": "foss4g-asia-2023-1957-un-open-geo-ai-for-un-by-maria-a-brovelli", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/D3XYHN/", "title": "[UN] - Open Geo-AI for UN by Maria A.

However, accurately capturing the intricate physical nature of basin hydrology through parameterized representations remains a formidable challenge, particularly in regions with limited or unavailable gauge sites, a prevalent scenario in developing nations and remote locales. A notable trend has recently emerged where remote sensing inversion products or reanalysis data, such as evapotranspiration, soil water, and leaf area index, are increasingly used as substitutes for ground truth observations in the calibration of hydrological models. But this introduces a considerable risk when directly employing them for hydrological modeling as these products inherently harbor unknown errors.\r\n\r\nThis study intends to address the above challenges by proposing an adaptive procedural fitting algorithm to support multivariate calibration, employing an iterative stepwise approach. The algorithm simplifies the hydrological model into a directed graph, with each node representing a subprocess in the hydrological model. This allows for quantifying the impact of a parameter on each subprocess by considering the traversal relationship between the subprocess to which the parameter is attached and other subprocesses. Consequently, the iterative calibration process enables the updating of parameters at different levels or learning rates. Furthermore, two categories of methods were introduced to evaluate the outputs of subprocesses relative to their calibrated datasets: ground truth observations and non-observation data with unknown errors. One category employs standard metrics to evaluate the simulated data against observations, while the other utilizes multiple collocation methods to evaluate the simulation with the data with unknown errors. The proposed multivariate calibration framework offers an innovative approach to hydrological modelling, facilitating the effective utilization of increasingly abundant remote sensing products and reanalysis data to enhance the accuracy and reliability of hydrological models.\r\n\r\nThe presented approach has been realized through the utilization of an open-source GIS solution, integrating tools such as Python, xarray, geopandas, multiprocessing and SWAT to form an efficiently processed parallel program. The demonstration was applied in a case study conducted within the Malian river Basin situated in Gansu Province, China, involving the integration of remotely sensed ET products and gauged streamflow datasets to showcase the applicability and effectiveness of the proposed method.", "description": null, "recording_license": "", "do_not_record": true, "persons": [{"code": "X8DABN", "name": "Song, Xianfeng", "avatar": null, "biography": null, "public_name": "Song, Xianfeng", "guid": "52e8107c-61ab-50c9-8a24-ac6069b78da7", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/X8DABN/"}, {"code": "AWL7SQ", "name": "Yan He", "avatar": "https://talks.staging.osgeo.org/media/avatars/photo_pa5EWNl.jpg", "biography": "PhD student from the College of Resources and Environment at the University of Chinese Academy of Sciences (UCAS), specializing in remote sensing hydrology.", "public_name": "Yan He", "guid": "91294823-46e2-5593-849a-4d7dbf8daf3a", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/AWL7SQ/"}, {"code": "98EFDJ", "name": "chen wang", "avatar": "https://talks.staging.osgeo.org/media/avatars/pic_39quT4t.jpg", "biography": "Master's student from the College of Resources and Environment at the University of Chinese Academy of Sciences (UCAS), specializing in remote sensing hydrology.", "public_name": "chen wang", "guid": "8ba2f38c-4f19-57ad-abc7-54739f8abea2", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/98EFDJ/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/MTXPRN/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/MTXPRN/", "attachments": []}, {"guid": "accad62e-97b3-5b52-a5e3-0a01d25df01c", "code": "UGY3XT", "id": 1731, "logo": null, "date": "2023-11-29T14:30:00+09:00", "start": "14:30", "duration": "00:20", "room": "Online Talks", "slug": "foss4g-asia-2023-1731-enhancing-hydrological-modeling-with-remote-sensing-evapotranspiration-products-impacts-of-dataset-qualities-and-aggregation-scales", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/UGY3XT/", "title": "Enhancing Hydrological Modeling with Remote Sensing Evapotranspiration Products: Impacts of Dataset Qualities and Aggregation Scales", "subtitle": "", "track": "Academic Track(Talks, Online Talks, Lightning Talks, Posters)", "type": "Online Talk", "language": "en", "abstract": "Remote sensing evapotranspiration (RS-ET) products have been the ubiquitous datasets of echo-hydrology, increasingly employed in precise hydrological modeling. However, these diverse ET products often offer considerable uncertainties, posing substantial challenges when incorporating them into hydrological models. This study aims to investigate the effects of integrating remote sensing evapotranspiration (RS-ET) products into the calibration of hydrological models. Specifically, we address two main questions: (1) among those RS-ET products considered, which offers the highest hydrologic predictability for hydrological modeling? (2) What is the optimal scale for incorporating RS-ET datasets into the hydrological model to achieve maximum benefits for enhancing hydrological modeling accuracy? \r\nWe conducted an in-depth exploration of these questions by implementing a hydrological modeling experiment using the Soil and Water Assessment Tool (SWAT) within the Meichuanjiang Basin in Jiangxi Province, China. This research employed four distinct RS-ET products: MOD16, GLASS, SSEBop, and ETMonitor, along with a merged product. Additionally, we examined three distinct scales for aggregating RS-ET datasets: subbasin (SUB), land use (LU), and hydrological response unit (HRU).\r\nOur findings revealed discernible variations in the evapotranspiration (ET) simulations of SWAT models across the study area, upon the calibration with five distinct products. Notably, GLASS and the fusion datasets demonstrated superior ET simulation performance with best scores, evaluated by a Kling-Gupta Efficiency (KGE) both surpassing 0.6. However, SSEBop yielded the lowest KGE of approximately 0.5. This study further highlighted that while the accuracy of ET simulations was enhanced, this improvement incurred a marginal cost in terms of a slight reduction in streamflow precision. However, this compromise was deemed acceptable due to its role in contributing to a more accurate spatial representation of catchment behavior while mitigating equifinality.\r\nSimilarly, at different scales of the same ET dataset used in calibration, although the differences in simulation results might be minimal, each dataset seems to have a specific optimal input scale. Notably, during the simulation of the evapotranspiration hydrological component, there is a particularly significant observation: the land use (LU) or subbasin (SUB) scale often proves to be more effective. The rationale for selecting the LU scale lies in the strong correlation between ET and various land use types. By analyzing each land use type separately, we can more accurately capture their distinct ET patterns, leading to improved simulation outcomes. Conversely, the enhanced effectiveness of the SUB scale can be attributed to the scale aggregation effect.\r\nConsidering that different RS-ET datasets and aggregation scales introduce uncertainty in observation data for calibration, we infer that the uncertainty in observation data gives rise to simulation uncertainty in inversing SWAT, subsequently backpropagating into parameter uncertainty. These findings shed light on the critical significance of carefully considering the quality of RS-ET datasets and the chosen aggregation scale in the context of hydrological modeling.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "X8DABN", "name": "Song, Xianfeng", "avatar": null, "biography": null, "public_name": "Song, Xianfeng", "guid": "52e8107c-61ab-50c9-8a24-ac6069b78da7", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/X8DABN/"}, {"code": "AWL7SQ", "name": "Yan He", "avatar": "https://talks.staging.osgeo.org/media/avatars/photo_pa5EWNl.jpg", "biography": "PhD student from the College of Resources and Environment at the University of Chinese Academy of Sciences (UCAS), specializing in remote sensing hydrology.", "public_name": "Yan He", "guid": "91294823-46e2-5593-849a-4d7dbf8daf3a", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/AWL7SQ/"}, {"code": "98EFDJ", "name": "chen wang", "avatar": "https://talks.staging.osgeo.org/media/avatars/pic_39quT4t.jpg", "biography": "Master's student from the College of Resources and Environment at the University of Chinese Academy of Sciences (UCAS), specializing in remote sensing hydrology.", "public_name": "chen wang", "guid": "8ba2f38c-4f19-57ad-abc7-54739f8abea2", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/98EFDJ/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/UGY3XT/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/UGY3XT/", "attachments": []}, {"guid": "b01b044a-b817-5c78-87fa-e72be01ab27f", "code": "MFVTEG", "id": 1667, "logo": "https://talks.staging.osgeo.org/media/foss4g-asia-2023/submissions/MFVTEG/aqli_aarsh_foss4GAsia2023_bwfLEvJ.png", "date": "2023-11-29T14:50:00+09:00", "start": "14:50", "duration": "00:20", "room": "Online Talks", "slug": "foss4g-asia-2023-1667-air-quality-life-index-aqli-a-free-and-open-source-global-interactive-tool-that-shows-the-impact-of-pollution-on-human-life-expectancy-around-the-world", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/MFVTEG/", "title": "Air Quality Life Index (AQLI): A free and open Source global interactive tool that shows the impact of pollution on human life expectancy around the world", "subtitle": "", "track": "General Track(Talks, Online Talks, Lightning Talks, Workshops)", "type": "Online Talk", "language": "en", "abstract": "Air pollution poses a significant health threat worldwide. As per a 2022 Lancet report (Pollution and health: a progress update), it accounts for 1 in 6 premature deaths, making it the largest environmental risk factor for disease and premature mortality.

Despite being pervasive, air pollution is often accepted as an unavoidable reality, forcing us to endure its detrimental health effects.\r\n\r\nHow can we effectively bridge this gap and nudge both public and policy makers alike to take action on the silent killer that is air pollution? \r\n\r\nThe AQLI tool is a free and open source interactive tool that attempts to address this global health crisis by estimating the relationship between PM2.5 and Life Expectancy allowing anyone to interactively visualize and explore the average gain in life expectancy they could experience if their community met the WHO PM2.5 guideline. AQLI also publishes an Annual Report and various regional factsheets. All of these resources, alongside our methodology, can be found on our website (https://aqli.epic.uchicago.edu/).\r\n\r\nSo far, the AQLI tool has been used in 216 countries by over 300,000 users.

There is an urgent need to take comprehensive measures to reduce air pollution in Ulaanbaatar, where half of the country's population lives and which has a coal-dependent energy supply. Within this, the research to create sustainable and environmentally friendly renewable energy has become a priority.\r\nAbout 48 percent of air pollution in Ulaanbaatar comes from households in ger districts. To reduce this amount, the need to use solar energy for their heating is required, so it is practical to estimate the potential amount of solar energy based on digital surface models. \r\nIn this study, we used Geographic Information System (GIS) to calculate the potential amount of solar energy resources in 6 districts of central Ulaanbaatar using a digital elevation model (DEM). The DEM was calculated from a topographic map with a scale of 1: 25000. In addition, objects such as buildings and trees were added to the Ulaanbaatar city database, and a numerical surface model was developed digital surface model (DSM) and used for further processing. The results were compared with the results of previous research. The results of this work are in line with previous estimates from meteorological data surveys. In the latitudes of Ulaanbaatar, the sunshine lasts 2,800 hours a year, which is relatively longer than in the highlands. The sun shines 145-170 hours in winter, 276-300 hours in spring for 3-4 months, 290-300 hours in summer, and 225-250 hours a month in autumn and summer.\r\nAccording to the study, the potential amount of solar energy resources was calculated on a total area of 206,705 hectares, and the maximum area that could store 1,200-1,500 kWh / m 2 of energy per year was 47,313 hectares. Excluding areas where it is not possible to build renewable energy facilities, such as sanitary restrictions, forests, cemeteries, farmland, special needs areas, reservoirs, waste disposal sites, and airport protection zones, 1100-1500 kWh per year. * 17,000 ha of potential energy storage area is within the boundaries of the construction restriction. This research is an unprecedented work in our country, as it calculates the potential amount of solar energy resources using a digital model of the surface.

This involves checking various aspects such as the user interface, APIs, business logic, data, as well as the integration of different functions to ensure proper alignment and compliance. This is crucial to instill confidence that the tested system will have minimal errors. Developers must conduct testing before deploying a system, whether it's a small feature, a mobile application, a machine, or various types of software, including web mapping.\r\n\r\nIn this presentation, we will explore a testing process specifically for web applications, which is the most popular approach for creating applications that can be used on both computers and mobile devices.

The essential task is to establish a systematic testing process that aligns with the designed functionalities.\r\n\r\nTesting the system involves not only manual processes but also technology frameworks that enable us to create automated test scripts. These scripts repeat tests on various functions within the web application, such as invoking the web application, navigating between pages, entering text, clicking buttons, and performing actions related to maps, such as setting zoom levels, panning, and toggling layers. This testing will be presented using an Automated Test Script Framework, which will guide further development and enhancement of testing for online web map applications, ensuring efficiency and maximum accuracy.\r\n\r\nThis is an interesting area of applying application testing processes to online web map applications, inviting those interested in enhancing and ensuring the accuracy of these applications to participate.

"Lightning Talk", "language": "en", "abstract": "To improve the safety of autonomous driving, ample data is required. However, obtaining driving data takes considerable manpower, and driving an autonomous vehicle is dangerous. Recently, vehicle driving simulations have been efficiently researched in the field of autonomous driving as a solution to this problem. However, these simulations are difficult to obtain for public users, and users must pay expensive license fees. Moreover, existing vehicle driving simulations can only be used in a limited environment because users have limited modification rights. Therefore, we want to develop a simulator with better accessibility than paid simulators and establish a simulation each user can acquire data in the customized environment. It will include the core functions of commercial simulators, such as setting the vehicle's route, creating a realistic environment, and acquiring the vehicle's sensor data. This simulator, implemented as a \"toolchain,\" incorporates open-source platforms.\r\nIn this study, we will integrate the open-source platforms 'Vehicle Route Planning Simulation Platform', '3D Vehicle Driving Simulation Platform', and '3D Road Modeling Tool'. The 'Vehicle Route Planning Simulation Platform' is specialized in planning the route of a vehicle, the '3D Vehicle Driving Simulation Platform' is developed to support autonomous driving systems so it is easy to obtain vehicle sensor data, and the '3D Road Modeling Tool' helps to build a realistic environment. Therefore, we adopted these platforms. Vehicle driving simulation have essential elements.\r\nWe need a Vector Map the vehicle references to drive and a 3D model to visualize it. Based on the vector map, the scenario of the vehicle is determined and the environment similar to the real world is created with the 3D model. To implement the actual vector map, we first download the road network in OSM format from Openstreetmap. And the road network is converted to a road network used by the 'Vehicle Route Planning Simulation Platform'(network). The network generates vehicle scenario(route) and 3D road data with road shape and properties through the 'Vehicle Route Planning Simulation Platform'. The 3D road data has a real-world environment by creating buildings and structures, vegetation, and the slope of the road using the 3D Road Modeling Tool. Import the previously created network file, route file, and 3D road data into the '3D Vehicle Driving Simulation Platform', and you can see the vehicles driving on a set route in the 3D simulator. Additionally, We define Camera, LiDAR, and GNSS sensors and assign the location and properties of the sensors. And we can obtain customized data. Using the method described above, we implemented a simulator based on the environment near the main gate of Seoul National University and obtain a camera, LiDAR, and GNSS data from 1000 vehicles at a time. The vehicle driving simulator creates a virtual mirror world of the real road. Moreover, simulators with open source can interact with various developers and improve rapidly, which is an opportunity to expand the simulator market. Furthermore, this research is expected to help develop algorithms to improve the location information of vehicles.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "P3ZFFZ", "name": "Impyeong Lee", "avatar": null, "biography": "Impyeong Lee is a professor in Dept. of Geoinformatics, University of Seoul, Korea.

Urban voids, characterized by underutilized or abandoned spaces, are prevalent in many cities and pose both challenges and opportunities for urban regeneration and development.\r\nThe integration of satellite imagery and GIS using open source software in this research allows for comprehensive mapping and analysis of the distribution and extent of urban voids in Coimbatore. The use of spectral and spatial analysis to classify these voids based on their characteristics, such as size, location, and land use patterns, provides valuable insights for understanding the current state of these spaces.\r\nThe focus on sustainable development and community-driven interventions is crucial for ensuring that the regenerated urban voids contribute positively to the city's overall fabric and cater to the needs and aspirations of the residents. By considering socio-economic indicators and involving the community in decision-making processes, the study can propose strategies that align with the local context, thereby increasing the chances of successful and inclusive urban regeneration.\r\nThe identification of suitable functions for each void, such as green spaces, recreational areas, or mixed-use developments, based on remote sensing data and socio-economic indicators is a commendable aspect of the research. By selecting appropriate functions, the regenerated spaces can serve as valuable assets for the community, contributing to their well-being and enhancing the urban environment.\r\nThe advocacy for integrating remote sensing technology into urban planning practices is well-founded. Evidence-based decision-making, enabled by remote sensing data, can significantly improve the efficiency and effectiveness of resource allocation and urban development initiatives. This data-driven approach ensures that urban regeneration efforts are well-informed and targeted, leading to better outcomes for the city and its residents.\r\nThe discussion on the broader applicability of remote sensing in urban regeneration efforts is highly relevant, as it encourages other cities facing similar challenges to embrace these tools and methodologies. Leveraging remote sensing technology can empower cities to make informed decisions, identify opportunities for regeneration, and create more vibrant, resilient, and sustainable urban environments.\r\nIn conclusion, the study on urban void regeneration in Coimbatore demonstrates the potential of remote sensing applications in addressing urban challenges and unlocking opportunities for sustainable development. By combining technological advancements with community engagement, the research offers a holistic approach to urban regeneration that can serve as a model for other cities seeking to revitalize underutilized spaces and create thriving urban environments.\r\n\r\nKeywords : Urban Voids, Open source software, Spatial Analysis, Urban Renewal, Geographic Information System (GIS)", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "DCCWPB", "name": "Prabhakaran Palanisamy", "avatar": "https://talks.staging.osgeo.org/media/avatars/PROFILE_7drPk5y.jpeg", "biography": "Architect and PhD scholar in Urban Studies.", "public_name": "Prabhakaran Palanisamy", "guid": "00fbec07-0a91-54f5-b961-84d59c768053", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/DCCWPB/"}, {"code": "ZAAYFU", "name": "CHANDRAMATHY", "avatar": null, "biography": null, "public_name": "CHANDRAMATHY", "guid": "0e07f4e4-018e-5961-b2ef-105e0832aab2", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/ZAAYFU/"}, {"code": "9KYMJ7", "name": "Salghuna N N", "avatar": null, "biography": null, "public_name": "Salghuna N N", "guid": "45719c63-54c0-511f-9b0c-f9545562d2c9", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/9KYMJ7/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/RER9UL/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/RER9UL/", "attachments": []}, {"guid": "109ff3f8-d52d-510b-8449-e851627a6edb", "code": "MDLWUX", "id": 1763, "logo": null, "date": "2023-11-30T13:30:00+09:00", "start": "13:30", "duration": "00:20", "room": "Seoul Archive", "slug": "foss4g-asia-2023-1763-detection-of-the-greenhouses-from-the-planetscope-satellite-image-using-the-yolo-algorithm", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/MDLWUX/", "title": "Detection of the greenhouses from the Planetscope satellite image using the YOLO algorithm", "subtitle": "", "track": "Academic Track(Talks, Online Talks, Lightning Talks, Posters)", "type": "Talk", "language": "en", "abstract": "A greenhouse is an important infrastructure for protecting out-of-season plants against extreme cold or hot weather.

A persistent challenge, however, is the precise extraction and delineation of building footprints, as traditional methods often yield results with irregular shapes and misalignments. To address these limitations, we present CornerRegNet, a pioneering deep neural network designed to predict oriented building corners and subsequently regularize building footprints derived from satellite imagery.\r\nCentral to CornerRegNet's design is its unique ability to harness oriented building corners as primary anchoring points. This approach significantly streamlines and refines the shape of the extracted building footprints. Using advanced multi-modal autoencoders, CornerRegNet adeptly embeds a blend of corner features, their inherent orientations, and overarching semantic context. This intricate fusion of features allows the network to capture micro-level details and macro-level building structural context.\r\nEnhancing the accuracy of corner prediction, the model incorporates active rotating filters. These filters, combined with uniquely devised equivariant convolutions, ensure that the predicted corners are not only spatially correct but also maintain their intended orientation concerning the building's overall layout.\r\nA pivotal component of CornerRegNet is the integrated Graph Convolution Network (GCN). This GCN is instrumental in iteratively refining the positions of corners from the preliminary footprints. Further, the in-built shape regularizer within the GCN aids in achieving architecturally consistent and coherent footprints, effectively minimizing typical extraction anomalies.\r\nIn comparative evaluations, CornerRegNet stands out, consistently outperforming contemporary models. The network's resilience in managing and regularizing building shapes is a distinguishing attribute, even under challenging scenarios marked by occlusions.\r\nIn conclusion, CornerRegNet represents a unique advancement in building footprint extraction from satellite imagery. Its unique combination of corner orientation prediction and shape regularization techniques sets new standards for accuracy, efficiency, and architectural interpretability.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "JZ8MEV", "name": "Gunho Sohn", "avatar": "https://talks.staging.osgeo.org/media/avatars/Gunho_Sohn-Small_Headshot_1_ptU9tHl.jpeg", "biography": "Dr. Gunho Sohn is a distinguished Associate Professor and Department Chair at the Department of Earth and Science and Engineering at York University.

Constructing a digital twin requires diverse forms of data based on the target area and purpose. To visualize vast and complex regions, data acquisition is partitioned into aerial and ground levels. In the aerial level, aircraft and UAVs are utilized, while on the ground, methods like Mobile Mapping Systems (MMS) and Terrestrial Laser Scanners (TLS) are employed. However, the registration of cross-view images, such as aerial-ground images, is challenging due to differences in field of view, hindering smooth image matching. While manual registration through tie points established by humans is possible, it comes at a high cost and time, thereby impeding the efficiency of digital twin construction. Recent advancements in deep learning-based image matching are enhancing the potential for the registration of cross-view images. In this study, deep learning image matching is employed to automate the registration of cross-view images, contributing to efficient digital twin construction. Tie points are generated through deep learning image matching between nadir/oblique UAV images acquired via autonomous flights and ground images captured by terrestrial laser scanners. Utilizing these tie points, bundle adjustment is performed, and a subset of tie points is extracted based on reprojection error criteria. By incorporating these extracted tie points, image registration is performed again to produce the result. Experimental results demonstrate successful registration of previously unregistered ground images, and the addition of ground-exclusive areas enhanced the performance of the 3D model.

This study employs an ANN-Cellular Automation model to simulate and\r\npredict future LULC maps in Chitwan District, Nepal. Three spatial variables, namely\r\nDEM, distance from road and river, and aspect play a significant role in predicting the\r\nLULC map of the area. The model achieves a high accuracy level, with a Kappa value\r\nof 0.95636 indicating a strong agreement between observed and predicted 2020 LULC\r\nmaps. By utilizing the 2010 and 2015 LULC maps in combination with the same spatial\r\nvariables, the study projects the LULC maps for 2020 and 2030. The results reveal that\r\ndue to anthropogenic pressures, there will be a conversion of forest land and other\r\ncategories into built-up and cropland areas. The study also identifies dynamic changes\r\nin land use and land cover patterns within Chitwan District. The area of water bodies\r\ninitially decreased from 76.88 sq. km in 2010 to 72.14 sq. km in 2015 but underwent a\r\nsignificant expansion to 99.81 sq. km in 2020 and further to 106.39 sq. km in 2030.\r\nForest area exhibits a minor reduction from 1506.14 sq. km in 2010 to 1528.78 sq. km\r\nin 2020, followed by a small increase to 1539.53 sq. km in 2030. Built-up areas witness\r\na steady increase from 3.90 sq. km in 2010 to 14.69 sq. km in 2020 and further growth\r\nto 18.86 sq. km in 2030. The agricultural area shows a decline from 597.05 sq. km in\r\n2010 to 519.36 sq. km in 2020, continuing the slight decline to 511.62 sq. km in 2030.\r\nThe study also observes an increase in the area of other wooded land from 35.99 sq. km\r\nin 2010 to 57.34 sq. km in 2020, but a subsequent decrease to 43.58 sq. km in 2030.\r\nAdditionally, the analysis of land surface temperature (LST) maps in December for\r\n2010, 2015, and 2020 reveals distinct patterns, with settlement areas consistently\r\ndisplaying higher temperatures than forest areas. These findings highlight the impact of\r\nland cover on local microclimates, potentially leading to increased urban heat island\r\neffects in settlements.

Efficient and accurate counting of cocoa fruits during harvest is essential for effective resource management, yield estimation, and overall productivity improvement. Traditional manual counting methods are time-consuming, labor-intensive, and susceptible to errors, necessitating the exploration of innovative technological solutions. \r\n\r\nThis research introduces a novel approach to automatic cocoa fruit counting using a mobile application integrated with computer vision techniques. The proposed system leverages four services: 1) acquisition of farmers monitoring data using the mobile devices, 2) develop explainable AI model for automatic cocoa fruit recognition, 3) presentation of Cocoa pod detection and counting services through a web & mobile based application and 4) collect the farmers feedback on cocoa pod count to improve the services. To do this, Mobile app for data collection was co-designed and tested with local farmers in Cameroon. This app allows farmers to take geo-tagged photographs and transfer them to the server when connectivity permits. In total, 2132 Cocoa tree photos were manually annotated and different artificial intelligence (AI) models (e.g., faster R-CNN, darknet, ResNet-50, mobilenetv3) were developed and tested for automatic counting of Cocoa pods. The Faster R-CNN model with a ResNet-50 performed better and provides accuracy above 70%. The model was deployed on a web service and provides real-time prediction through a web- & Mobile based application \r\n\r\nThe insights gleaned from this research will spawn a new generation of tools for Cocoa farmers to use. It is an efficient, non-destructive, and low-cost method which offers useful information for them to plan agricultural work and obtain economic benefits from the correct administration of resources.

In the Philippines, the prevalence rate is 1 in 122[2], totaling almost 350,000 affected Filipino children. \r\nChildren with Autism require 10 to 40 hours of therapy per week[3], encompassing various sessions like speech-language, occupational, and physical therapy, to foster crucial social and learning skills for integration. However, obtaining these interventions proves challenging due to high demand, uneven spatial distribution of resources, and a lack of centralized credible information source. Given these, tracking a child's milestones and progress often takes a back seat.\r\nEmpowering families in their search for suitable therapy or special education places is essential. Location emerges as a key factor after service availability, warranting an updated, comprehensive, and credible map.\r\nAusome Maps, a She Leads and She Inspires grant project funded by the Humanitarian OpenStreetMap Team via the Open Mapping Hub Asia-Pacific. It aims to map schools with special education classes, therapy clinics, and institutions aiding differently abled Filipinos on OpenStreetMap. Initially, out of over 5000 identified school points of interest (POIs), only 12 were tagged as 'special needs', with fewer than 10 POIs tagged as places for therapy. \r\nAusome Maps conducted events to raise autism awareness, elucidate map importance, teach about open data and mapping on OpenStreetMap, and offer hands-on training on data gathering, engineering, and other related activities. To date, over 500 students, professionals, and families have been part of Ausome Maps\u2019 journey through these sessions.\r\nAusome Maps has completed the tag updating of schools with special education classes with existing feature in OpenStreetMap. Remaining schools to be tagged \u2013 40%, predominantly private schools, will be on OpenStreetMap following further data completion and integrity check. For the places of therapy, Ausome Maps have successfully completed and validated 70% of the national datasets provided by the Philippine Association of Speech Pathologists and Philippine Academy of Occupational Therapists. \r\nUsing Map Roulette, Ausome Maps was able to conduct beginner friendly mapathons. Kobo Toolbox allowed us to reach out to our community and solicit support in gathering primary-sourced information or data validation about either the schools or therapy centers.\r\nMoving forward, Ausome Maps continues to create a replicable activities framework that will enable for the same impact to be recreated in other regions. A part of the project\u2019s bid for continued impact, a platform called TherapEase is under development. \r\nTherapEase will incentivize users \u2013 families and intervention providers \u2013 to ensure data about schools and therapy centers on the platform is up to date.

By integrating Uber H3 indexing with Postgres, we can improve the performance of PostGIS, especially for operations that involve partitioning of data, distance calculations and zonal statistics\r\n\r\nThis talk will demonstrate the use of Uber H3 indexing library in Postgres for geospatial data processing through a series of examples and benchmarks. The proposed presentation will showcase the benefits of using Uber H3 indexing for geospatial data processing in Postgres, such as improved query performance and better partitioning of data. \r\n\r\nThe proposed presentation will be of interest to developers, data scientists, and geospatial analysts who work with geospatial data in Postgres. It will provide a practical guide to integrating Uber H3 indexing with Postgres, and offer insights into the performance gains and applications of this integration.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "8MGXWG", "name": "json singh", "avatar": "https://talks.staging.osgeo.org/media/avatars/json-singh-foss4geu-tartu_gVIJ9Ce.jpeg", "biography": "I have been honing my skills in the geospatial domain, gaining diverse experience in Climate tech startups, Agritech solutions, and more.\r\nMy experience extends to working with satellite data (including Sentinel and Landsat), geospatial data modeling, and handling large datasets at scale in the cloud using Docker, Python, S3, etc\r\nI am most interested in building a generic spatial-temporal database that can handle a wide variety of data and use cases.", "public_name": "json singh", "guid": "b45c2a31-c5ab-5f44-af94-ad71e1e24a9d", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/8MGXWG/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/RXLXXV/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/RXLXXV/", "attachments": []}, {"guid": "96476d2f-b692-5886-bf94-9877c9d87306", "code": "DDYFMD", "id": 1725, "logo": null, "date": "2023-11-30T11:00:00+09:00", "start": "11:00", "duration": "00:20", "room": "Workshop Room", "slug": "foss4g-asia-2023-1725-a-user-oriented-foss-solution-for-lcz-mapping-the-lcz-odc-project", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/DDYFMD/", "title": "A user-oriented FOSS solution for LCZ mapping: the LCZ-ODC project", "subtitle": "", "track": "General Track(Talks, Online Talks, Lightning Talks, Workshops)", "type": "Talk", "language": "en", "abstract": "Local Climate Zone (LCZ) maps represent a valuable informative tool for several applications including outdoor thermal comfort assessment, building energy consumption, and microclimate modelling. Typically, these maps are produced by taking advantage of multispectral satellite imagery and multiple geospatial layers (e.g. topographic databases and land use/land cover maps), according to established workflows. Nonetheless, cutting-edge data and technologies leave large room for improvement. Furthermore, different features in terms of map accessibility, format and resolution may be required for the different applications depending on the end-users' needs. This is why user requirements should be gathered and addressed during the mapping workflow\u2019s design and implementation.\r\nIn view of the above considerations, the LCZ-ODC project (agreement n. 2022-30-HH.0), funded by the Italian Space Agency (ASI), aims to produce multi-temporal LCZ maps for the Metropolitan City of Milan, in northern Italy, using innovative open data sources and Free and Open Source Software (FOSS) tools. The project is being carried out from a user-oriented perspective to achieve high levels of usability while fulfilling different end-user informational needs. Stakeholders, including public administration, professional associations, foundations, and researchers, are actively involved in the project development and validation phases through dedicated workshops and educational events aiming to consolidate user needs, guide product implementation, and assess the usability of the project outcomes.\r\nThe LCZ-ODC project uses a hybrid remote sensing/Geographic Information System (GIS) based approach for LCZ mapping, utilizing both open geospatial layers and high-resolution satellite imagery. The latter include multispectral Sentinel-2 images distributed by the European Space Agency (ESA) and hyperspectral data acquired by the PRISMA (Hyperspectral Precursor of the Application Mission) satellite, provided by ASI. Additionally, in-situ weather measurements sensed by authoritative monitoring networks are used to assess the statistical correlation between the LCZ classes and air temperature.\r\nThe Open Data Cube (ODC) technology serves as the project\u2019s backend system, facilitating multi-source data integration, pre-processing, and the distribution of ready-to-use data. In particular, geospatial layers contained in the ODC include multi-temporal and multi-resolution LCZ maps, preprocessed satellite images, and static layers describing the LCZ morphological properties, like sky-view factor, building height, and impervious surface fraction. A preconfigured ODC instance will be published in a Docker container, equipped with libraries and tools needed for interacting with and downloading the available datasets. Moreover, Jupyter Notebooks will be made available as a project outcome, enabling non-expert users to easily visualize, query, and download the data from the ODC. These Notebooks also offer documentation and ready-to-use code for expert users, streamlining the data analysis and exploration process.\r\nThe ongoing work focuses on developing interactive and user-friendly interfaces to allow users with different levels of expertise to directly access and interact with the data contained in the ODC.

The semantic information of each point (such as walls, floors, doors, windows, etc.) is essential to handle and analyzing point clouds. However, the raw point cloud captured from the LiDAR sensor doesn\u2019t have semantics, and the annotation task for adding semantics is time-consuming and needs expert experience with commercial software. Therefore, we set up two goals for accelerating the 3D point clouds annotation task:\r\n- Machine-based assistants, such as AI techniques, and\r\n- Task-based collaboration.\r\n\r\nRecently, deep learning has been used to derive semantic classes by automated classification and segmentation. Therefore, it can be used to address the manual task (bottleneck) in the traditional annotation process. Also, the data format for deploying is essential for collaboration. It should be easy to understand and efficient to share.\r\n\r\nPCAS (Point Cloud Annotation System) is a 3D point cloud annotation system that enhances the quality and speed of annotation tasks with deep learning techniques. This system can be summarized as four key points:\r\n- This system mainly develops based on Potree[1], an open-source library for point cloud visualization. It also utilizes various open sources, such as open3d[2] and torch-points3d[3], for handling point clouds with deep learning modules.\r\n- This system supports three tools to accelerate annotation work: semi-automatic labeling with a deep learning module, 3D shape object-based labeling, and normal vector-based cluster labeling.\r\n- The annotation task can be easily shared and tracked, similar to GitHub.\r\n- The annotation task results are stored as an HDF5 file based on a predefined profile[4] for the labeled point clouds, easily sharing and managing semantic information.\r\nThis talk will introduce the four main points above, including the structure of PCAS with other open sources, the design purpose, and problems and solutions encountered during development.\r\n\r\nReferences:  \r\n[1] Potree, WebGL point cloud viewer for large datasets, https://github.com/potree/potree  \r\n[2] torch-points3d, Pytorch framework for doing deep learning on point clouds, https://github.com/torch-points3d/torch-points3d  \r\n[3] Open3D, A Modern Library for 3D Data Processing, https://github.com/isl-org/Open3D  \r\n[4] The HDF5 profile for labeled point cloud data, https://docs.ogc.org/dp/21-077.html", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "CJCQGN", "name": "Wijae Cho", "avatar": null, "biography": "National Institute of Advanced Industrial Science and Technology (AIST)", "public_name": "Wijae Cho", "guid": "5044fc39-e701-59ad-94d9-9e4e71bd6c8d", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/CJCQGN/"}, {"code": "U8WE7U", "name": "Taehoon Kim", "avatar": "https://talks.staging.osgeo.org/media/avatars/20190804_171001_74DhynM.jpg", "biography": "Taehoon is a Researcher at Data Platform Research Team (DPRT), Artificial Intelligence Research Center (AIRC), AIST, Japan.\r\nHe also works as an OGC API-MovingFeatures co-editor.\r\nHis major research areas include spatio-temporal databases, mobility analysis, indoor spatial analysis, GIS data modeling, and data mining.", "public_name": "Taehoon Kim", "guid": "077cf221-216b-5c2e-a76d-8f2c3f22a628", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/U8WE7U/"}, {"code": "UKCKWU", "name": "Kyoungsook Kim", "avatar": null, "biography": null, "public_name": "Kyoungsook Kim", "guid": "de72cc6b-497d-55e5-bbfb-73072fb8e06b", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/UKCKWU/"}], "links": [], "feedback_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/GF8WUG/feedback/", "origin_url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/GF8WUG/", "attachments": []}, {"guid": "5495b730-2ad9-5a09-8c59-ecbe9ef787d5", "code": "KJJLNG", "id": 1677, "logo": null, "date": "2023-11-30T11:40:00+09:00", "start": "11:40", "duration": "00:20", "room": "Workshop Room", "slug": "foss4g-asia-2023-1677-fair-free-and-open-source-ai-for-humanitarian-mapping", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/talk/KJJLNG/", "title": "fAIr - Free and Open Source AI for Humanitarian Mapping", "subtitle": "", "track": "General Track(Talks, Online Talks, Lightning Talks, Workshops)", "type": "Talk", "language": "en", "abstract": "The name fAIr is derived from the following terms:\r\n\r\nf: for freedom and free and open-source software\r\nAI: for Artificial Intelligence\r\nr: for resilience and our responsibility for our communities and the role we play within humanitarian mapping\r\n\r\nfAIr is an open AI-assisted mapping service developed by the Humanitarian OpenStreetMap Team (HOT), designed to enhance the efficiency and accuracy of mapping efforts for humanitarian purposes.

Such contrail radiative forcing should be amplified when multiple occurrences of these anthropogenic clouds are grouped spatio-temporally as \u2018contrail outbreaks\u2019 and contrail cirrus on at least 1 \u00d7 103 km2, extending over approximately 104~105 km2, and persisting for approximately 1-6 h. To more definitively determine the net radiative forcing of contrails and their role in contemporary and future climate changes, and to establish appropriate climate change mitigation strategies (e.g., jet flight activity regulation), it is essential to reliably detect contrail incidence and assess the spatio-temporal distribution of contrail outbreaks as well as understand the underlying mechanisms of contrail formation. \r\n\r\nThanks to recent advanced technologies, one can obtain flight tracking data as well as automate an individual contrail occurrence detection on the satellite or aerial images and alleviate the burden of labor-intensive manual contrail detection tasks. In this context, our COVID-Contrail project aims to (1) assess the changes of contrail occurrence patterns and relevant atmospheric factors in the continental United States (CONUS) before and during COVID-19 and (2) develop an automated data processing and analysis system to construct and publish a massive contrail incidence database in high spatio-temporal resolution.

According to Japan's Ministry of Land, Infrastructure, Transport and Tourism, the lifespan of infrastructure is 50 years after construction, but the number of infrastructure facilities that have exceeded their lifespan is increasing every year. On the other hand, inspections are still conducted visually by facility managers, and the inability to properly conduct detailed inspections due to a lack of engineers has become a social issue. Furthermore, conventional visual inspections lack consistency due to the large variation in results from one inspector to another. To address these issues, we developed a web system that automatically detects cracks, one of the inspection items, by object detection, and manages and visualizes the results using location information. In this study, we focused on cracks located on the apron's top of a quay wall, one of the port facilities. In the inspection process, we first used a small general-purpose drone to automatically photograph the inspection target and create orthophotos. The orthophotos are then uploaded to a crack detection web system. The system segments the uploaded orthophoto into smaller sections and uses object detection to locate cracks in the segmented image. Using the detection results and the orthophoto's location information, the system calculates the detected cracks' location. The results are displayed on the orthophoto and output in GeoJSON format, which has the advantage that it can be easily combined with other geographic information data using QGIS for analysis and comparative analysis based on time series. In addition, the system can perform everything from crack detection to display and download of results centrally on the Web, making it easier and faster for inspectors to proceed with their inspections. This new method, which involves detecting cracks through object detection and acquiring consistent quality aerial images through automated drone flight, improves inspection efficiency while reducing the variability of inspection results.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "EEZFDM", "name": "Daiki Komi", "avatar": null, "biography": "I am a student of Graduate School of Informatics at Osaka Metropolitan University.\r\nI am researching infrastructure maintenance and management using drones.", "public_name": "Daiki Komi", "guid": "ac85cf63-cd9b-55d2-ba07-8dd3495b90d6", "url": "https://talks.staging.osgeo.org/foss4g-asia-2023/speaker/EEZFDM/"}, {"code": "CN7D8H", "name": "Tomohito Kameyama", "avatar": null, "biography": "I am a student of Graduate School of Informatics at Osaka Metropolitan University.

the dual objectives of pedestrian safety and effective robot navigation in shared spaces. A comprehensive 3D digital twin model, replicating real-world urban settings, was designed to simulate the multifaceted engagements between humans, robots, and the urban fabric. Incorporated within this simulation was the Pedestrian Aware Model (PAM), a multi-agent system, employed to mimic both robot and human movements.\r\n\r\nEmploying an agent-based modeling approach, a series of scenarios involving pedestrians, wheelchair users, and robots coexisting in sidewalk spaces were dissected. The salient revelation from this study is the non-contributory role of robots to sidewalk congestion. Through programmed safety buffer zones, robots not only ensure pedestrian safety but also facilitate streamlined navigation, hinting at a feasible harmonious integration.\r\n\r\nDespite this, the study unearthed certain challenges. Robots were predominantly implicated in collisions, whereas pedestrians often infringed upon set distance thresholds, emphasizing the imperative for enhanced strategic measures to alleviate these risks. However, the overarching inference remains optimistic: with judicious design and continuous research, robots have the potential to integrate seamlessly with pedestrians, enriching the urban milieu. The simulation model posited in this study stands as a pivotal resource for urban planners and policymakers, guiding them in formulating strategies and policies for smooth robot-human cohabitation.\r\n\r\nQuantitative analyses further cement the significance of this research, underscoring nuances like the importance of ample safety buffers around robots to minimize collisions and enhance sidewalk traffic fluidity.

Considering content construction cost, having 3D buildings of LOD 1 is regarded cost-effective for location-based visualization and simulation. 3D buildings of LOD 1 layer without texture can be easily created by extruding the building heights from building footprint's planar geometry. 3D building models are processed to be a streamable tileset over the web. To apply enormous number of building features at nation-wide scale, a global tileset by merging external tilesets was implemented.   \r\n\r\nThe author has implemented creating 3D buildings of LOD 1 and tiling it as a streamable tileset of 3D Tiles. Per each building feature, 3D COLLADA model with local coordinate was created from buliding footprint's geometry of shapefiles by FME Desktop. In order to manage each building's metadata, KML reference model per building is applied while 3D model is linked as a COLLADA file. At a building footprint's centroid location, a KML is created containing longitude, latitude, altitude and linking a corresponding COLLADA file. The metadata in KML is generated from shapefile's attributes by a custom bash shell script. When KML/COLLADA models are ready, Cesium ion 3D Tiling Pipeline is used to create a per-building tileset of 3D Tiles. As the number of building features grow up to nation-wide scale, managing a single tileset is not only difficult to create but also causing network payloads. To resolve these issues, tilesets are granulated at manageable level and merged as a global tileset by merging external tilesets using open source 3D Tiles Tools.

This is made possible with the use of Earth Observation (EO) data retrieved from multi-spectral satellite imagery openly available to the public domain through the Copernicus and Landsat program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) respectively. EO data has several advantages. It is supported by national governments, and inter-governmental agencies maintaining access to the data publicly available. It is free and open for use by researchers, governments, and by the commercial sector. The project areas are three municipalities in the island of Mindoro, Region IV-B MIMAROPA, Philippines. Specifically in the province of Occidental Mindoro. The three municipalities are the provincial capital, the Municipality of Mamburao, and the other two are the Municipalities of Rizal and Sablayan. The World Wide Fund for Nature \u2013 Philippines (WWF) commissioned the Community Environmental Economic and Social Accounting Matrix (CEESAM) study for these three municipalities in support of its expanded sustainable livelihood project for Tuna production and fisherfolk. This study\u2019s component for spatial analysis is in support of the CEESAM for these municipalities. In summary, the study produced a land cover classification map achieving an average overall accuracy of 80% computed for all three municipalities. This is a good result since the accepted practice of achieving an overall accuracy within that 80% range is commendable. Processing the land cover classification was complemented with in situ observations using aerial imagery from light commercial drones and from ground based mobile imagery through QFIELD. Referencing the different imagery from earth observation data to aerial drone imagery, and ground based field observations led to the identification of spatial challenges and opportunities per municipality.\r\n\tThe study presented a workflow with a use-case for utilizing earth observation data using the latest and available update satellite imagery, complemented by in situ observations from aerial drone imagery and mobile field mapping app QFIELD. Also, the municipalities included in the study have common issues with regards to intermittent power interruption. Disruption in this vital utility slows down the production of any processing or cold chain facilities. Agricultural production primarily focus on annual crops for staples such as rice and corn. Mono cropping dominates the agricultural landscape with pockets of perennial crops which have room to integrate with traditional agriculture. Some areas have unfinished or unpaved farm to market roads. This results to inefficient logistics for the farmers in taking their produce to market. This could also add additional cost for them. Further, there is still a need for improving on post-harvest and post-catch support for farmers and fisherfolk with regards to facilities and market linkage facilitation.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "SRQYFG", "name": "Francis Josef Gasgonia", "avatar": "https://talks.staging.osgeo.org/media/avatars/DSC_0016_0ZZZ1kg.jpg", "biography": "Mr. Francis Josef C.

The OSM data has been developed from approaches like Maxar and Bing Imagery helps to address the local level issues during the climate change and disaster. However, in densely populated urban area, the mentioned imagery resolution does not seem to fulfill the necessary resolution required to produce the digital data. In such a case the high resolution imagery is required. Hence, this study has adopted advanced approach of integrating high-resolution drone imagery, facilitated by OSM platform. The study is conducted in the Banepa Municipality of Nepal. With an aim of collecting the inventory of roof top which are feasible for farming, the concept of Volunteered Geographic Information System (VGIS) has been applied. A multi criteria analysis including Roof Shape, Tin Roof, Buildings Materials, Water tanks. Solar Panels, collected by VGIS technique, was used to extract suitable rooftop areas. Total number of houses in study area is 1055. The result shows 10.23 % (505.2 m2) are already adopting rooftop farming. Housing structure shows that 1.7 %   are temporary, 54 % are concrete houses which include 16.68 % (Single flat roofs) and 37.25 % (double roofs), 16.1 % (with solar panels), and 47.86. % (with water tank). The preliminary analysis suggest that 54.02 % houses (approximately 48500 m2 ) are potential roof top farming areas identified by excluding Tin roof, water tank and solar panel areas. Having these data collected, the main aims of this study is to describe the methodological process and the strength and weakness identified during the process of developing the data inventory by OSM by integrating OAM.
