The GHS-BUILT-C spatial raster datasets, derived from Sentinel-2 composite (2018), delineate the boundaries of the human settlements at 10m resolution, and describe their inner characteristics in terms of the morphology of the built environment and the functional use. The Morphological Settlement Zone (MSZ) delineates the spatial domain of all the human settlements at the neighbourhood scale of approx. 100m, based on the spatial generalization of the built-up surface fraction (BUFRAC) function. The objective is to fill the open spaces that are surrounded by large patches of built space.
MSZ, open spaces, and built spaces basic class abstractions are derived by mathematical morphology and spatial filtering (opening, closing, regional maxima) from the BUFRAC function. They are further classified accordingly to the information regarding vegetation intensity, water surfaces (GHS_LAND_GLOBE), road surfaces (OSM highways), functional use (GHS-BUILT-C), and building height (GHS-BUILT-H).
