Returns the feature collection with selected properties.
Usage Returns FeatureCollection. select (propertySelectors, newProperties , retainGeometry )
FeatureCollection
Argument Type Details this: featurecollection
FeatureCollection The FeatureCollection instance. propertySelectors
List A list of names or regexes specifying the attributes to select. newProperties
List, optional A list of new names for the output properties. Must match the number of properties selected. retainGeometry
Boolean, optional When false, the result will have a NULL geometry. Defaults to true.
Examples
Code Editor (JavaScript)
// FeatureCollection of power plants in Belgium.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
.filter('country_lg == "Belgium"');
// Select a single property.
var singleProp = fc.select('fuel1');
print('Single property selected',
singleProp.first());
// Select multiple properties.
var multiProp = fc.select(['fuel1', 'capacitymw']);
print('Multiple properties selected',
multiProp.first());
// Select multiple properties and rename them.
var multiPropRename = fc.select({
propertySelectors: ['fuel1', 'capacitymw'],
newProperties: ['Fuel_1', 'Capacity_MW']
});
print('Multiple properties selected, renamed',
multiPropRename.first());
// Select multiple properties, remove geometry.
var multiPropNoGeom = fc.select({
propertySelectors: ['fuel1', 'capacitymw'],
retainGeometry: false
});
print('Multiple properties selected, geometry removed',
multiPropNoGeom.first());
