[4] The data forms a base for OpenStreetMap in the US, and also was used for the initial import of US map data into the Waze navigation system.
WorldPop develops statistical population modelling methods to produce gridded population estimates that support census activities. [11] [12] The programme develops new methods for data synthesis that use demographic and health surveys, census, satellite imagery, [13] cell phone [14] and other data to create consistent gridded outputs [15] and map detailed population densities.
