| description:
|
The legend includes 10 generic classes that appropriately describe the land surface at 20m: "trees cover areas", "shrubs cover areas", "grassland", "cropland", "vegetation aquatic or regularly flooded", "lichen and mosses / sparse vegetation", "bare areas", "built up areas", "snow and/or ice" and "open water".
It is a prototype built after reviewing various existing typologies, including LCCS and LCML, as well as global and national experiences (such as GLC-share, GlobeLand30, Global Surface Water product from JRC/EC, Global Human Settlement Layer from JRC/EC, Global Urban Footprint from DLR, Africover, and SERVIR-RMCD). The Random Forest (RF) and Machine Learning (ML) classification algorithms were also chosen to transform the cloud-free reflectance composites into a land cover map. The two maps resulting from both approaches were then combined either to select the best representation of a land cover class or, in case of unreliable LC class delineation, the reference layer (based on 1 year of Sentinel-2 A satellite observations from December 2015 to December 2016) is used to consolidate the land cover classification.
