Gridded Population of the World, Version 4 (GPWv4) Land and Water Area, Revision 11 grids measure surface areas of land and water in square kilometers per pixel. The land area grid provides estimates of the land area, excluding permanent ice and water, within each pixel, and was used to calculate the population density grids. The water area grid provides estimates of the water area (permanent ice and water), within each pixel. The sum of land area and water area of a pixel equals the total surface area of that pixel. The files for this data set were produced as global grids at 30 arc-seconds horizontal resolution (approximately 1km at the equator). To enable faster global processing, and in support of research communities, the 30 arc-second data was aggregated to 2.5 arc-minutes, 15 arc-minutes, 30 arc-minutes and 1 degree resolutions.
