Description
This raster dataset represents a global, multitemporal rural-urban classification, applying the "Degree of Urbanisation" stage I methodology recommended by UN Statistical Commission, based on global gridded population and built-up surface data generated by the GHSL project for the epochs 1975-2030 in 5-year intervals. The Degree of Urbanisation layers have been generated by integrating information on built-up surface extracted from Landsat and Sentinel-2 data GHS-BUILT-S R2023, and gridded population data derived from CIESIN GPW v4.11 GHS-POP R2023. This product is an update of the data released in 2023 based on the updates of the GHS-BUILT-S and GHS-POP. The Settlement Model is provided at the detailed level (Second Level - L2). The first-level classification can be obtained by aggregating L2.
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 Center, and Directorate-General for Regional and Urban Policy.
