ee.ImageCollection.toBands

컬렉션의 모든 이미지의 모든 밴드를 포함하는 단일 멀티밴드 이미지로 컬렉션을 변환합니다. 출력 밴드는 기존 밴드 이름에 출처 이미지 ID를 접두사로 붙여서 지정됩니다 (예: 'image1_band1').

참고: 최대 밴드 수는 5,000개입니다.

코드 편집기(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);
