Urban Center Database 2025 - Land Use, Greenness, SDG

The GHS Urban Centre Database (GHS-UCDB) describes spatial entities called “Urban Centres” described through a set of multi-temporal thematic attributes from the GHSL data combined with other free and open data sets. The UCDB is a global dataset of over 10,000 urban centers developed by the European Commission, providing multi-temporal and multi-thematic information based on a globally harmonized methodology. It supports global monitoring of policy frameworks and provides data for urban studies. Resolution is 1km. This Layer covers the Land-use/Land-cover, Greenness and Sustainability Development Goals thematic domains. Under these the GHS-UCDB groups a variety of families and indicators, further divided in specific attributes, multitemporal (1980-2020). Attributes include land use & land cover, greenness in built-up area, population growth rate, land consumption rate and share of poulation living in high green area. Zusätzliche Informationen The Global Human Settlement Layer (GHSL) project produces global spatial information, evidencebased analytics, and knowledge describing the human presence on the planet. The GHSL relies on the design and implementation of spatial data processing technologies that allow automatic data analytics and information extraction from large amounts of heterogeneous geospatial data including global, fine-scale satellite image data streams, census data, and crowd sourced or volunteered geographic information sources.
