资源简介：
The Global Gridded Relative Deprivation Index (GRDI), Version 1 (GRDIv1) data set characterizes the relative levels of multidimensional deprivation and poverty in each 30 arc-second (~1 km) pixel, where a value of 100 represents the highest level of deprivation and a value of 0 the lowest. GRDIv1 is built from sociodemographic and satellite data inputs that were spatially harmonized, indexed, and weighted into six main components to produce the final index raster. Inputs were selected from the best-available data that either continuously vary across space or have at least administrative level 1 (provincial/state) resolution, and which have global spatial coverage.
全球格网相对剥夺指数（GRDI）版本1（GRDIv1）数据集描绘了每个30弧秒（约1公里）像素中多维剥夺和贫困的相对水平，其中100表示剥夺程度最高，0表示剥夺程度最低。GRDIv1通过空间协调、索引和加权六项主要组成部分，从连续变化于空间或至少具有行政级别1（省/州）分辨率、并拥有全球空间覆盖的最佳可用数据中构建而成，最终生成该指数栅格。数据输入选择自最佳可用数据，这些数据要么在空间上连续变化，要么至少具有行政级别1（省/州）的分辨率。
