Google Earth Engine(GEE) ——世界人口网格化第4版行政单位中心点与人口数据集

世界人口网格化第4版行政单位中心点与人口估计
世界人口网格化第4版（GPWv4）。带有人口估计的行政单位中心点，修订版11包括2000年、2005年、2010年、2015年和2020年的联合国世界人口方案调整后的人口估计和密度，以及2010年的基本人口特征（年龄和性别）。该数据集还包括行政名称、土地和水域面积，以及按行政单位中心点（中心点）位置划分的数据背景。中心点是基于GPWv4中使用的大约1350万个输入行政单位，因此，这些文件需要能够将大量数据读入内存的硬件和软件。

目的：提供GPWv4中使用的输入行政单位的矢量（点）版本，包括人口估计、密度、2010年基本人口特征，以及行政名称、面积和数据背景，以便在数据整合中使用。

代码：

var gpw = ee.FeatureCollection("projects/sat-io/open-datasets/sedac/gpw-v4-admin-unit-center-points-population-estimates-rev11");

Map.addLayer(ee.FeatureCollection(gpw),{},'gpw-v4-admin-center-points-rev11')
