使用Google Earth Engine中图像集合中每个单独图像的波段值填充FeatureCollection

// 导入Google Earth Engine库
var ee = require('users/google/earthengine:ee');

// 创建一个FeatureCollection
var fc = ee.FeatureCollection();

// 获取图像集合
var imageCollection = ee.ImageCollection('图像集合ID');

// 将图像集合转换为列表
var imageList = imageCollection.toList(imageCollection.size());

// 遍历图像列表
for (var i = 0; i < imageList.length().getInfo(); i++) {
  // 获取图像
  var image = ee.Image(imageList.get(i));

  // 选择需要的波段
  var selectedBands = image.select(['波段1', '波段2']);

  // 计算FeatureCollection中每个要素的波段值
  var stats = selectedBands.reduceRegion({
    reducer: ee.Reducer.mean(),
    geometry: fc,
    scale: 30
  });

  // 将波段值添加到FeatureCollection中
  fc = fc.map(function(feature) {
    var newFeature = feature.set(stats);
    return newFeature;
  });
}

// 打印FeatureCollection
print(fc);
