| 説明 | Gridded Population of the World, Version 4 (GPWv4) National Identifier Grid, Revision 11 is a raster representation of nation-states in GPWv4. It is produced from the input census units which are used to create a raster surface where pixels (grid cells) covering the same data source - most often a country or territory - have the same value. These data represent the area covered by the input data as provided, and are not official representations of country or territory boundaries. Each country or territory is assigned a color arbitrarily. |
