openEO
Land cover statistics based on ESA WorldCover data for 2021, provided by Terrascope.
2021 landcover statistics
Computes landcover statistics over multiple areas, based on the ESA WorldCover product.
As input, the service takes GeoJSON, which can also be a FeatureCollection defining multiple feature.
The output is a csv file containing the fraction of a specific landcover present in each area.
This service is maintained and provided by Terrascope.
Methodology
The European Space Agency (ESA) WorldCover 10 m 2021 product provides a global land cover map for 2021 at 10 m resolution based on Sentinel-1 and Sentinel-2 data. The WorldCover product comes with 11 land cover classes, aligned with UN-FAO’s Land Cover Classification System, and has been generated in the framework of the ESA WorldCover project.

geometries (required) Geometries for which the statistics will be computed, as a GeoJSON FeatureCollection. Feature properties are preserved for vector data cubes and all GeoJSON Features. One value will be computed per label in the dimension of type `geometries`, GeoJSON `Feature` or `Geometry`. For a `FeatureCollection` multiple values will be computed, one value per contained `Feature`. No values will be computed for empty geometries. For example, a single value will be computed for a `MultiPolygon`, but two values will be computed for a `FeatureCollection` containing two polygons. - For **polygons**, the process considers all pixels for which the point at the pixel center intersects with the corresponding polygon (as defined in the Simple Features standard by the OGC). - For **points**, the process considers the closest pixel center. - For **lines** (line strings), the process considers all the pixels whose centers are closest to at least one point on the line. Thus, pixels may be part of multiple geometries and be part of multiple aggregations. No operation is applied to geometries that are outside of the bounds of the data. | object/geojson |
