Comprehensive dataset information and technical specifications
Dataset Information
The ESA WorldCover Team is proud to announce the release of the WorldCover 2021 product at 10m resolution.
Inspired by the 2017 WorldCover conference organized by ESA, the cardinal requirements are:
fast generation and validation of a world land cover based on Sentinel-2 and Sentinel-1 constellations 10 land cover classes + mangroves 10m resolution 10 months from last data take 77% overall accuracy, independently validated The WorldCover products are delivered in a regular latitude/longitude grid (EPSG:4326) with the ellipsoid WGS 1984 (Terrestrial radius=6378 km). The legend includes 11 generic classes that appropriately describe the land surface at 10m: "Tree cover", "Shrubland", "Grassland", "Cropland", "Built-up", "Bare / sparse vegetation”, “Snow and Ice”, “Permanent water bodies”, “Herbaceous Wetland”, “Mangrove” and “Moss and lichen".
