Cet ensemble de données raster représente la distribution des surfaces construites, exprimée en mètres carrés par cellule de grille de 10 m, pour 2018, telle qu'observée à partir des données d'images S2.
Les ensembles de données mesurent : a) la surface bâtie totale et b) la surface bâtie allouée aux cellules de grille à usage non résidentiel (NRES) prédominant.
Le projet Global Human Settlement Layer (GHSL) est soutenu par la Commission européenne, le Centre commun de recherche et la Direction générale de la politique régionale et urbaine.
