Google Earth Engine（GEE）——全球8,502个污水处理厂（WWTPs）数据集

HydroWASTE v1.0 HydroWASTE是一个空间上明确的全球数据库，包括58,502个污水处理厂（WWTPs）及其特征。该数据库是通过将国家和地区的数据集与辅助信息结合起来，得出或完成缺失的特征，包括服务的人数、污水的流速和处理后的废水水平。带有水流估算的HydroSHEDS河网被用来对工厂的排污口位置进行地理参照，并在全球范围内评估废水的分布。所有的废水处理厂都通过其估计的排污口位置共同注册到HydroRIVERS数据库的全球河流网络中。你可以在这里找到数据集页面

// Visualization for HydroWASTE
var table = ee.FeatureCollection("projects/sat-io/open-datasets/HydroWaste/HydroWASTE_v10");


var typeColor = ee.Dictionary({
  'Primary': 'fc8d59',
  'Secondary': '542788',

var type = ['Primary', 'Secondary', 'Advanced'];

function addStyle(pt) {
  var size = ee.Number(pt.get('WASTE_DIS')).sqrt().divide(100);

}

var pp = ee.FeatureCollection(table).map(addStyle);
Map.addLayer(pp.filter(ee.Filter.eq('LEVEL', 'Primary')).style({styleProperty: 'styleProperty'}), {}, 'Primary', true,0.65);
