In this talk\, we will discuss TerraBrasilis' development\, updates\, and improvements. We b uilt the portal's front-end and back-end using free and open-source softwa re.\nINPE’s program named BiomasBR is responsible for long term projects that generate the official data about the Brazilian biomes. These project s process Earth observation satellite images with the goal of generating a ccurate and timely data to support the country in monitoring and controlli ng deforestation\, forest degradation\, forest fire\, and other environmen tal impacts on the Brazilian Amazon forest and other biomes. In this talk\ , we address specifically the projects PRODES and DETER. The Real Time Def orestation Detection System (DETER) uses Earth observation satellite image ry to map and report changes in forest cover across the Amazon and the Cer rado biome. As a result\, DETER produces\, every day\, sets of polygons\, referred to as alerts\, that delineate areas where deforestation or degrad ation (such as mining\, forest fire scars\, or logging) can be perceived. Each DETER alert includes the image date that generated it\, the type of c hange\, and other attributes. DETER uses images from sensors with high tem poral resolution and large swath width\, with the appropriate spectral ban ds to detect vegetation cover change. Currently\, DETER uses mainly data f rom the Wild Field Imager (WFI) on board the Amazonia-1 and the China-Braz il Earth Resource Satellite (CBERS-4A). Command-and-control organizations use the data produced by DETER to plan and qualify field actions.\nThe Leg al Amazon Deforestation Satellite Monitoring Project (PRODES) maps\, annua lly\, the suppression of native vegetation in Brazil. Initially\, the proj ect restricted its scope to the Legal Amazon region\, conducting an annual inventory of forest loss dating back to 1988. In 2001\, the project expan ded its scope to include the monitoring of Cerrado biome. PRODES uses medi um resolution imagery with the appropriate spectral bands to detect vegeta tion cover change. It uses images from the Operational Imager (OLI) sensor on board the Landsat-8 satellite\, the Multispectral Camera (MUX) from CB ERS-4 and CBERS-4A\, and the Multispectral Instrument (MSI) from Sentinel- 2. PRODES data has supported long-term public policies to contain native v egetation removal in the Amazon and the Cerrado. Currently\, the project h as expanded to encompass all Brazilian biomes. PRODES data support public policies\, greenhouse gas emission estimates\, and can help release intern ational resources associated with conservation\, climate\, and biodiversit y agendas. \nPRODES and DETER generate a large volume of geospatial data u seful to a several organizations. Given the strategic importance of these projects\, and INPE’s commitment to geospatial open source and open data \, the TerraBrasilis portal is the one-stop point to access PRODES and DET ER data. The portal is used by the Brazilian government\, academic and pr ivate sectors\, non-governmental organisations\, and the general public in terested in environmental issues. As such\, TerraBrasilis is a way to ensu re INPE’s transparency regarding the environmental data it generates. It allows anyone to explore land cover data without requiring further knowle dge.\nThe main functional requirements and characteristics that guide the development of TerraBrasilis are: multiplicity of users\, with different t echnological backgrounds and different interests\; data might be subject t o temporal embargo before being public\; temporal embargo might be overcom e by authorized users\; data is related to the same process\, but has a di stinct production timetable and distinct time granularity\; data has to be presented as a web map with the conventional operations of zooming\, pan\ , layer selection\, etc.\; data summaries should be available with common visualization tools such as graphs\, charts\, and tables\; users need to m ake comparisons over time and different spatial units of interest\, such a s municipalities\, states\, indigenous lands\, or conservation units\; dat a can be downloaded in open formats\; data can be accessed through open ge ospatial services.\nConsidering these requirements TerraBrasilis is design ed as a set of multiple independent panels\, to expose different views of its geospatial database. A series of scripts connect to the production dat abase and prepare the data for publishing in TerraBrasilis. The publishing database contains over 2 PB of raster and vector data\, and this volume i ncreases daily. It contains data for Brazil's entire territory. Some datas ets date back to 1988.\nPRODES and DETER data are available in distinct we b mapping panels that allow the visualization of multiple layers\, spatial and temporal filtering\, as well as the download of data in open formats such as GeoTIFF and Shapefile. They are also available in interactive dash boards where users can make comparisons over time and different spatial un its of interest\, such as municipalities\, states\, or conservation units. \nTerraBrasilis uses a service-oriented paradigm that follows interoperabl e international spatial data standards and the specifications of the Brazi lian National Spatial Data Infrastructure (INDE). TerraLib offers Open Geo spatial Consortium (OGC)-compliant services such as Web Map Service (WMS)\ , Web Feature Service (WFS)\, Web Service Coverage (WCS) and Catalog Servi ce for the Web (CSW).\nTerraBrasilis publishes all of the data generated i n DETER and PRODES\, and it is constantly evolving. Recently\, the portal has developed and integrated some panels that integrate data from PRODES a nd DETER\, along with other data sources such as INPE's vegetation fire mo nitoring project in Brazil. The Situation Room panel\, for example\, allow s the observation of critical areas of deforestation and vegetation fire\, through a series of indicators based on data from DETER and other environ mental indicators. In this talk\, we will provide a general overview of th e portal\, the technical aspects of its development\, and the data present ed in TerraBrasilis.
