ee.FeatureCollection.copyProperties

Copia propriedades de metadados de um elemento para outro.

Uso	Retorna
FeatureCollection.copyProperties(source, properties, exclude)	Elemento

Argumento	Tipo	Detalhes
isso: destination	Elemento, padrão: null	O objeto cujas propriedades serão substituídas.
source	Elemento, padrão: null	O objeto de onde as propriedades serão copiadas.
properties	Lista, padrão: nulo	As propriedades a serem copiadas. Se omitido, todas as propriedades comuns (ou seja, não do sistema) serão copiadas.
exclude	Lista, padrão: nulo	A lista de propriedades a serem excluídas ao copiar todas as propriedades. Não pode ser especificado se "properties" for.

Exemplos

Editor de código (JavaScript)

// 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']
