Abstract

Recent years have seen substantial growth in openly available satellite and other geospatial data layers, which represent a range of metrics relevant to global human population mapping at fine spatial scales. The specifications of such data differ widely and therefore the harmonisation of data layers is a prerequisite to constructing detailed and contemporary spatial datasets which accurately describe population distributions. Such datasets are vital to measure impacts of population growth, monitor change, and plan interventions. To this end the WorldPop Project has produced an open access archive of 3 and 30 arc-second resolution gridded data. Four tiled raster datasets form the basis of the archive: (i) Viewfinder Panoramas topography clipped to Global ADMinistrative area (GADM) coastlines; (ii) a matching ISO 3166 country identification grid; (iii) country area; (iv) and slope layer. Further layers include transport networks, landcover, nightlights, precipitation, travel time to major cities, and waterways. Datasets and production methodology are here described. The archive can be downloaded both from the WorldPop Dataverse Repository and the WorldPop Project website.

Figure 1. Schematic overview of the workflow used to produce the WorldPop Archive as 100 m tiles and 1 km global mosaics.
The preparation of the 100 m base grids (topography, slope, country ID, and country area) is here described (yellow panels), and the methodology for preparing the accompanying 1 km mosaics defined (orange panel). Further data layers, subsequently incorporated into the archive, are summarised (in green); and the methodological approach outlined (blue). For detailed workflow and description of base datasets and further layers please see the Methods section.

Layers (in ascending order) are topography; slope; country ID; country area; Globcover land cover; GPW v4 (ref. 11) population count; GPW v4 (ref. 11) population density; Landsat water; and OSM water, highways, rail network, railway stations, runways, and heliports.
