ESA WorldCover is the world's most detailed global land cover map at 10-meter resolution, providing comprehensive land use and land cover information derived from European Space Agency (ESA) Sentinel-1 and Sentinel-2 satellite observations.
Developed as part of ESA's Copernicus programme, WorldCover offers free access to unprecedented detail about Earth's land surface, including forests, croplands, urban areas, water bodies, and other land cover types, making it essential for environmental monitoring, climate research, and sustainable development planning.
Whether you're working on deforestation monitoring, urban planning, agricultural assessment, or biodiversity conservation, ESA WorldCover provides the high-resolution land cover intelligence needed for informed decision-making.
