ee.FeatureCollection.copyProperties

한 요소에서 다른 요소로 메타데이터 속성을 복사합니다.

사용	반환 값
FeatureCollection.copyProperties(source, properties, exclude)	요소

인수	유형	세부정보
다음과 같은 경우: destination	요소, 기본값: null	속성을 재정의할 객체입니다.
source	요소, 기본값: null	속성을 복사할 객체입니다.
properties	목록, 기본값: null	복사할 속성입니다. 생략하면 모든 일반 (즉, 시스템이 아닌) 속성이 복사됩니다.
exclude	목록, 기본값: null	모든 속성을 복사할 때 제외할 속성 목록입니다. 속성이 지정된 경우 지정하면 안 됩니다.

// Import a Landsat 8 surface reflectance image to sample.
var image = ee.Image('LANDSAT/LC08/C02/T1_L2/LC08_038032_20170722')
                // Select the optical bands.
                .select(['SR_B.']);

// Get the image geometry to define the geographical bounds of the sample.
var imageBounds = image.geometry();

// Sample the image at a set of random points; a feature collection is returned.
var pointSampleFc = image.sample(
    {region: imageBounds, scale: 30, numPixels: 5, geometries: true});

// Copy image properties to the FeatureCollection; three options follow.
print('All non-system image properties copied to the FeatureCollection',
      pointSampleFc.copyProperties(image));

print('Selected image properties copied to the FeatureCollection',
      pointSampleFc.copyProperties({
        source: image,
        properties: ['system:time_start', 'SPACECRAFT_ID']
      }));

print('All but selected image properties copied to the FeatureCollection',
      pointSampleFc.copyProperties({
        source: image,
        exclude: ['TIRS_SSM_MODEL', 'TIRS_SSM_POSITION_STATUS']
