资源简介:
The Gridded Population of the World, Version 3 (GPWv3): National Identifier Grid is derived from the land area grid to create a raster surface where pixels (cells) that cover the same country or territory have the same value. Note that the countries and territories are not official representations of countries boundaries; rather, they represent the area covered by the statistical data as provided. GPWv3 is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with Centro Internacional de Agricultura Tropical (CIAT).
《世界栅格人口,第3版》(GPWv3):国家标识网格是基于土地面积网格构建的,其中覆盖相同国家或地区的像素(单元格)具有相同的数值。需注意的是,国家与地区并非官方边界表示;相反,它们代表所提供统计数据覆盖的面积。GPWv3由哥伦比亚大学国际地球科学信息网络中心(CIESIN)与热带国际农业研究中心(CIAT)合作制作。
