Copies metadata properties from one element to another.
Usage Returns FeatureCollection. copyProperties (source , properties , exclude )
Element
Argument Type Details this: destination
Element, default: null The object whose properties to override. source
Element, default: null The object from which to copy the properties. properties
List, default: null The properties to copy. If omitted, all ordinary (i.e. non-system) properties are copied. exclude
List, default: null The list of properties to exclude when copying all properties. Must not be specified if properties is.
Examples
Code Editor (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' ]
}));
