GHS-BUILT describes the percent built-up area for each 30 arc-second grid cell (approximately 1 km at the equator) based on Landsat imagery from each of the four time periods. GHS-POP consists of census data from the 2010 round of global census from Gridded Population of the World, Version 4, Revision 10 (GPWv4.10) spatially-allocated within census Units based on the percent built-up areas from GHS-BUILT. GHS-SMOD uses GHS-BUILT and GHS-POP in order to develop a standardized classification of degree of urbanization grid. The original data from the Joint Research Centre of the European Commission (JRC-EC) has been combined into a single data package in GeoTIFF format and reprojected from Mollweide Equal Area into WGS84 at 9 arc-second and 30 arc-second horizontal resolutions in order to support integration with a variety of global raster data sets.", "distribution": [{"@type": "dcat:Distribution", "description": "Documentation Page", "downloadURL": "https://sedac.ciesin.columbia.edu/data/set/ghsl-population-built-up-estimates-degree-urban-smod/docs", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "Sample browse graphic of the data set.", "downloadURL": "https://sedac.ciesin.columbia.edu/downloads/maps/ghsl/ghsl-population-built-up-estimates-degree-urban-smod/ghsl-population-built-up-estimates-degree-urban-smod-pop-2015-thumbnail.jpg", "format": "JPEG", "mediaType": "image/jpeg", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.7927%2Fh4154f0w", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Web Map Service Page", "downloadURL": "https://sedac.ciesin.columbia.edu/data/set/ghsl-population-built-up-estimates-degree-urban-smod/maps/services", "format": "HTML", "mediaType": "text/html", "title": "Use Web Map Service (WMS) to download the dataset's data"}], "identifier": "C2098218461-SEDAC", "issued": "2021-07-29", "keyword": ["earth-science", "human-dimensions", "human-settlements", "population"], "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "SEDAC"}, "references": ["https://doi.org/10.7927/tg7r-n260"], "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "1975-01-01T00:00:00Z/2015-01-01T00:00:00Z", "theme": ["GHSL", "geospatial"], "title": "Global Human Settlement Layer: Population and Built-Up Estimates, and Degree of Urbanization Settlement Model Grid"}
