Participants will learn how to download relevant WaPOR datasets and compute key water productivity indicators to support sustainable agricultural practices.\n\nBy the end of this workshop \, you are able to:\n\n* describe WaPOR datasets and their significance in monitoring water productivity and efficiency in agriculture.\n* use the W aPLUGIN to directly download relevant datasets for agricultural analysis.\ ncompute various indicators such as Uniformity of Water Consumption\, Bene ficial Fraction\, Adequacy\, and more using the seasonal maps and the WaPL UGIN Indicators Calculator.\n* create a visually appealing map in QGIS.

The workshop materials will be available in English and Du tch.\n\nMesh data is a type of unstructured grid that represents spatial s tructures in either 2D or 3D space\, often incorporating temporal and othe r components. Its versatility makes it ideal for applications in fields su ch as meteorology\, hydrodynamics\, and environmental modeling.\n\nThrough out the workshop\, you'll explore topics such as visualizing and animating mesh data\, working with NetCDF data formats in QGIS\, and styling flow d irection using arrows. The tutorials and resources provided aim to equip l earners with practical skills for effectively handling mesh data.

Seamlessly integrated with QGIS\, it empowers users to efficiently capture\, synchronize\, and share geospatial data.\n\nThis presentation will provide an in-depth explo ration of Mergin Maps\, including:\n* An introduction to its features and QGIS integration\n* Dealing with data synchronization and conflict resolut ion\n* Insights from a real-world success story and case study\n* Highligh ts of its latest features and advancements\n\nJoin us to discover how Merg in Maps streamlines geospatial workflows and fosters effective collaborati on.

This nocturnal cooling varies between slacks due to differences in their geomorphological characteristics\, influencing local biodiversity and the broader ecosystem.\n\nThis study focuses on the automated detection of dun e slacks using freely available geospatial data in QGIS. A dynamic thresho lding parameter will be developed to accurately delineate dune slacks base d different attributes. Following detection\, each slack will be indexed a nd ranked according to geomorphological parameters to indicate their relat ive thermal behavior—ranging from coldest to warmest.\n\nThe methodology will integrate LiDAR-derived Digital Terrain Models (DTMs)\, in-situ temp erature measurements\, and other open-source spatial datasets. This approa ch not only streamlines the identification of dune slacks but also lays th e groundwork for informed conservation strategies and deeper ecological in sights into climate-sensitive dune environments.

We zijn een compact maar dichtbevolkt land\, e n daar hoort een hoge versteningsgraad van het landschap bij. In detail we ten waar Nederland versteend is\, en waar niet\, ondersteunt beleid dat he t verschil kan maken tussen gezond waterbeheer en miljarden aan economisch e schade\, tussen leven en dood.\nDe stichting Friedenau Society heeft in opdracht van de Vereniging Nederlandse Gemeenten gewerkt aan een open land kaart van Nederland\, met 25 centimeter resolutie. De kaart vertelt niet o f een plek “steen” of “groen” is\, maar legt in 19 klassen de mate van verharding uit. De kaart kijkt ook onder bomen\, een standaard tekort koming in eerdere versteningskaarten. Ook onder bomen leggen we vast of ee n plek verhard\, half-verhard\, open grond of struik is. Het framework zal worden gebruikt voor het monitoren door de tijd van de ontwikkeling van d e versteningsgraad van het landschap.\nDeze landkaart is gemaakt met behul p van open source tools\, en zal beschikbaar worden gesteld als open algor itmen en open data. In deze presentatie willen we ingaan op de aanpak van deze open landelijke dataset\, en op de impact die we hiermee proberen te maken voor een goed klimaatbeleid in Nederland.
