It uses a water mask to exclude water and permanent ice from population data. The dataset, named GPWv4, Revision 11, allocates population proportionally from census data. The water mask identifies water pixels, differentiating between total and partial water, land, and ocean pixels. It can be accessed via an Earth Engine snippet and is freely available for research, education, and nonprofit use under CC-BY-4.0 license.\n"]]
