expand_more What is MapBiomas?
The MapBiomas project is an initiative of the Climate Observatory co-created and developed by a multi-institutional network involving universities, NGOs, and technology companies with the purpose of annually map Brazil's land-use and land cover and monitor the changes in the territory.
expand_more What is MapBiomas Pampa Sudamericano?
MapBiomas Pampa Sudamericano is an initiative that arises as a continuation of the initiative in Brazil that involves a collaborative network of specialists from Argentina, Brazil and Uruguay, in topics such as land use, satellite remote sensing, GIS and programming. It uses cloud processing and automated classifiers developed and operated from the Google Earth Engine platform to generate a historical series of annual maps of land use and cover in the South American Pampa.
expand_more Who produces MapBiomas Pampa Sudamericano maps?
MapBiomas Pampa Sudamericano involves researchers and specialists in remote sensing, GIS, informatics, biomes and land uses in each of the participating countries (Argentina, Brazil and Uruguay). The team from Brazil includes the Rio Grande do Sul University (UFRGS, Universidade Federal do Rio Grande do Sul) and GeoKArten. In Uruguay, the team includes the University of the Republic (UR, Universidad de la República), the National Institute of Agricultural Research (INIA, Instituto Nacional de Investigación Agropecuaria) and the Ministry of Environment (Ministerio de Ambiente). Finally the team from Argentina includes the National Institute of Agricultural Technology (INTA, Instituto Nacional de Tecnología Agropecuaria), the Institute of Applied Mathematics of the University of San Luis (IMASL, Instituto de Matemática Aplicada de la Universidad de San Luis) and Fundación Vida Silvestre (FVSA). The teams work in coordination by processing the information in the cloud through the Google Earth Engine platform.
expand_more How can I download maps from MapBiomas Pampa Sudamericano?
The maps can be downloaded directly on the platform through the link: Collection Maps
Do not forget to download the legend codes in: Download
It is also possible to download the data directly from Google Earth Engine when specific territorial or temporary breaks are needed.
In Google Earth Engine it is possible to access all Landsat Mosaic data and transition maps. To obtain the IDs of the MapBiomas Pampa Sudamericano collections in Google Earth Engine, access: Assets
expand_more Why are maps shown only in raster format?
Land use and land cover maps made on the MapBiomas Pampa scale (30m pixel) and large time series are impractical in vector format. All data processing is performed in raster format, pixel by pixel.
expand_more Can I download the data in Shapefile format?
There is no such possibility in the MapBiomas Pampa Sudamericano platform. The vectorization of maps is extremely expensive and impractical for the whole territory. The recommended solution, if you want to work with vectors, is to download the data, make the territorial or spatial cut of your interest and then vectorize with your favorite software.
expand_more Is the MapBiomas Pampa Sudamericano data public?
Yes, the MapBiomas Pampa Sudamericano data is public and free for non-commercial use or for public interest purposes.
expand_more Is it possible to work with MapBiomas Pampa Sudamericano data in the cloud without having to download them?
Yes, the MapBiomas Pampa Sudamericano collections are available as layers in the Google Earth Engine platform and can be accessed, processed and analyzed directly on the platform without the need to download the data. To obtain the IDs of the MapBiomas Pampa Sudamericano collections in the Google Earth engine, go to: Link.
expand_more How can I access MapBiomas Pampa South American data in Google Earth Engine?
It is necessary to have an account in Google Earth Engine (GEE), which can be created through the following link: https://earthengine.google.com
By accessing the GEE Code Editor (https://code.earthengine.google.com) you can start scripts to view and process data. In this link you will find examples of scripts to access the MapBiomas Pampa Sudamericano data in Google Earth Engine.
expand_more How can I cite the MapBiomas Pampa Sudamericano data?
The data of MapBiomas South American Pampa are public and free, simply referring to the source in the following format:
"MapBiomas MapBiomas South American Pampa Project - Collection [version] of the annual maps of land cover and land use, accessed at [date] through the link: [LINK]. The MapBiomas South America Pampa project is a multi-institutional initiative to generate annual land use maps based on automatic classification processes applied to satellite images. The complete description of the project can be found at https://pampa.mapbiomas.org/ "
expand_more Where do I find the detailed description of the legend and the meaning of each caption code?
The detailed description of the legend with the correspondent code (raster) is available for download at: LINK
expand_more Can I download tabular and statistical data of the land use and land cover maps? To which territorial subsets?
Yes, land use and land cover statistics, as well as transitional matrices for the biomes (Pampa, Espinal (Argentina) y Delta del Paraná (Argentina)), countries, states, and departments are available for download at: Statistics
expand_more How to download maps from a state or department?
Inside the MapBiomas Pampa Sudamericano platform, the maps are available and ready to use, clipped by Biomes. For states and municipalities subsets, it can be generated inside Google Earth Engine, by accessing the script available at link. You must select the state and county and years of interest and export it to your Google Drive folder.
expand_more How is the area of MapBiomas Pampa Sudamericano raster data calculated?
Landsat has an average resolution of 30m, so it is common to associate the area of a pixel to 900 m2. But, since the original MapBiomas Pampa Sudamericano data is created following the GEE standard representation (Lat/Long and WGS84), it does not use a native equal-area projection. Thus, the distance from the target to the Equator Line influences the pixel size. Therefore, in the continental scale area, calculation counting the pixels and multiplying by 900 m2 should be avoided.
In MapBiomas Pampa Sudamericano the calculation is performed within Google Earth Engine. We apply the function ee.Image.pixelArea() that generates an image in which the value of each pixel is the area of that pixel in square meters, taking into consideration occasional cartographic distortions.
