Global Gridded Relative Deprivation Index (GRDI), v1 (2010-2020)
收藏资源简介:
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.
全球网格化相对剥夺指数(Global Gridded Relative Deprivation Index,简称GRDI)第1版(GRDIv1)数据集刻画了每30角秒(约1公里)栅格单元内的多维度剥夺与贫困相对水平,其中数值100代表剥夺程度最高,数值0代表剥夺程度最低。GRDIv1以社会人口学与卫星遥感数据为输入数据源,经空间协调、索引构建与加权处理后,整合为六大核心维度,最终生成该指数栅格产品。该数据集的输入数据均选自当前可获得的最优公开数据,这些数据要么具备空间连续变化特性,要么至少达到一级行政区(省级/州级)的空间分辨率,且具备全球空间覆盖范围。
