The GHS Urban Centre Database (GHS-UCDB) describes spatial entities called “urban centres” according to a set of multitemporal thematic attributes gathered from the GHSL sources integrated with other sources available in the open scientific domain.
The Urban Centres are defined by specific cut-off values on resident population and built-up surface share in a 1x1 km uniform global grid.
This data can be visually explored in the Urban Centres database section of our website (based on data version v1.0).
On the 18/04/2020 A new update (v1.2) of the Urban Centre Database UCDB R2019A has been released to be downloaded.
