Gridded Population of the World, Version 4 (GPWv4): Data Quality Indicators, Revision 10
The Gridded Population of the World, Version 4 (GPWv4): Data Quality Indicators, Revision 10 consists of three data layers created to provide context for the population count and density rasters, and explicit information on the spatial precision of the input boundary data. The Data Context raster explains pixels with a "0" population estimate in the population count and density rasters based on information included in the census documents, such as areas that are part of a national park, areas that have no households, etc. The Water Mask raster distinguishes between pixels that are completely water and/or ice (Total Water Pixels) and pixels that also contain land (Partial Water Pixels). The Mean Administrative Unit Area raster represents the mean input unit size in square kilometers and provides a quantitative surface that indicates the size of the input unit(s) from which population count and density rasters are created. The data files were produced as global rasters at 30 arc-second (~1 km at the equator) resolution. To enable faster global processing, and in support of research communities, the 30 arc-second data were aggregated to 2.5 arc-minute, 15 arc-minute, 30 arc-minute and 1 degree resolutions.
