將兩個圖片集合併為一個。結果會顯示兩個集合中的所有圖片。

用量傳回
ImageCollection.merge(collection2)ImageCollection
引數類型詳細資料
這個：collection1ImageCollection要合併的第一個集合。
collection2ImageCollection要合併的第二個集合。

範例

程式碼編輯器 (JavaScript)

// Sentinel-2 surface reflectance image collection.
var ic = ee.ImageCollection('COPERNICUS/S2_SR');

// Filter the images to those that intersect Mount Shasta for 3 months
// in 2019 and 2021 (two image collections).
var geom = ee.Geometry.Point(-122.196, 41.411);
var ic2018 = ic.filterBounds(geom).filterDate('2019-07-01', '2019-10-01');
print('2018 image collection', ic2018);
var ic2021 = ic.filterBounds(geom).filterDate('2021-07-01', '2021-10-01');
print('2021 image collection', ic2021);

// Merge the two image collections.
var icMerged = ic2018.merge(ic2021);
print('Merged image collection', icMerged);
