ee.FeatureCollection.select

Select properties from each Feature in a collection. It is also possible to call this function with only string arguments; they will be all be interpreted as propertySelectors (varargs).

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());
