🌿 MapBiomas Ecuador – Land Cover Classification Scripts

MapBiomas Ecuador monitors land use changes at a national scale using multitemporal mapping, allowing the analysis of ecosystem pressures and human expansion.
To produce annual historical land use and land cover maps, the initiative uses tools such as Google Earth Engine and collaborates with experts.
By 2025, Ecuador developed Collection 3.0, covering the entire national territory (including the Galápagos Islands), going beyond the Amazon region.

🥸 General Features

MapBiomas Ecuador maps are generated using machine learning in Google Earth Engine through pixel-by-pixel classification of Landsat imagery.

🚀 Methodological Description and Steps

  • Landsat data collection
  • Pixel-by-pixel processing (30m x 30m)
  • Organized by tiles (1° x 1.5° Lat/Long)
  • Cloud-based processing

🎋 Cross-cutting Themes
