Description
This raster dataset depicts the distribution of built-up surfaces, expressed in square metres per 10 m grid cell, for 2018 as observed from the S2 image data.
The datasets measure: a) the total built-up surface, and b) the built-up surface allocated to grid cells of predominant non-residential (NRES) use.
The complete information about the GHSL main products can be found in the GHSL Data Package 2023 report
The Global Human Settlement Layer (GHSL) project is supported by the European Commission, Joint Research Centre, and Directorate-General for Regional and Urban Policy.
