Ce jeu de données raster représente la distribution des surfaces construites, exprimée en mètres carrés par cellule de grille de 100 m.
L'ensemble de données mesure : a) la surface bâtie totale et b) la surface bâtie allouée aux cellules de grille à usage non résidentiel (NRES) prédominant. Les données sont interpolées ou extrapolées de manière spatio-temporelle de 1975 à 2030, par intervalles de cinq ans.
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.
