ee.ImageCollection.toBands

將集合轉換為單一多波段影像，其中包含集合中每張影像的所有波段。輸出頻帶的命名方式是在現有頻帶名稱前加上來源圖片的 ID (例如 'image1_band1')。注意：樂團數量上限為 5,000 個。

範例

程式碼編輯器 (JavaScript)

// A Landsat 8 TOA image collection (2 months of images at a specific point).
var col = ee.ImageCollection('LANDSAT/LC08/C02/T1_TOA')
  .filterBounds(ee.Geometry.Point(-90.70, 34.71))
  .filterDate('2020-07-01', '2020-09-01')
  .select('B[4-5]');  // Get NIR and SWIR1 bands only.
print('Collection', col);

// Convert the image collection to a single multi-band image. Note that image ID
// ('system:index') is prepended to band names to delineate the source images.
var img = col.toBands();
print('Collection to bands', img);

// Band order is determined by collection order. Here, the collection is
// sorted in descending order of the date of observation (reverse of previous).
var bandOrder = col.sort('DATE_ACQUIRED', false).toBands();
print('Customized band order', bandOrder);
