WorldCover 2020 LAND

European Space Agency WorldCover 2020 LAND

Water-related raster values are tagged as EXCLUDED. Excluded values are ignored when calculating the effective area of a reporting unit. Percentage metrics are based on the effective area of a reporting unit, not the total area.

No coefficient values for impervious area, nitrogen loading, or phosphorous loading calculations are provided.

        <description>WorldCover 2020 LAND Land Cover Classification Schema. Water-related raster values are tagged as EXCLUDED. Excluded values are ignored when calculating the effective area of a reporting unit. Percentage metrics are based on the effective area of a reporting unit, not its total area (i.e., class area / effective area * 100 = metric value).  WorldCover is a 10 m resolution 2020 global land cover product from the European Space Agency (ESA) based on both Sentinel-1 and Sentinel-2 data, containing 11 land cover classes.</description>
