ee.FeatureCollection.copyProperties

Copia las propiedades de metadatos de un elemento a otro.

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

Argumento	Tipo	Detalles
esta: destination	Elemento, valor predeterminado: nulo	Objeto cuyas propiedades se anularán.
source	Elemento, valor predeterminado: nulo	Objeto desde el que se copiarán las propiedades.
properties	Lista, valor predeterminado: null	Son las propiedades que se copiarán. Si se omite, se copian todas las propiedades comunes (es decir, las que no son del sistema).
exclude	Lista, valor predeterminado: null	Es la lista de propiedades que se excluirán cuando se copien todas las propiedades. No se debe especificar si se indica properties.

// 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({
