Ten rastrowy zbiór danych przedstawia rozkład powierzchni zabudowanych wyrażony w metrach kwadratowych na komórkę siatki o wymiarach 100 m x 100 m.
Zbiór danych zawiera pomiary: a) całkowitej powierzchni zabudowanej i b) powierzchni zabudowanej przypisanej do komórek siatki o przeważającym zastosowaniu niemieszkalnym (NRES). Dane są interpolowane lub ekstrapolowane przestrzennie i czasowo w 5-letnich odstępach od 1975 r. do 2030 r.
Projekt Global Human Settlement Layer (GHSL) jest wspierany przez Komisję Europejską, Wspólne Centrum Badawcze oraz Dyrekcję Generalną ds. Polityki Regionalnej i Miejskiej.
