ee.FeatureCollection

FeatureCollections can be constructed from the following arguments:

  - A string: assumed to be the name of a collection.

  - A single geometry.

  - A single feature.

  - A list of features.

  - A GeoJSON FeatureCollection

  - A computed object: reinterpreted as a collection.

Usage	Returns
ee.FeatureCollection(args, column)	FeatureCollection

Argument	Type	Details
args	ComputedObject|Feature|FeatureCollection|Geometry|List	The constructor arguments.
column	String, optional	The name of the geometry column to use. Only useful when working with a named collection.

Examples

// FeatureCollection from a string (collection name). Note that this only works
// with client-side strings, it won't accept computed, server-side strings.
var collectionName = 'WRI/GPPD/power_plants';
var collectionNameFc = ee.FeatureCollection(collectionName);
print('FeatureCollection from a string', collectionNameFc.limit(5));

// FeatureCollection from a single geometry.
var singleGeometry = ee.Geometry.Point(-62.54, -27.32);
var singleGeometryFc = ee.FeatureCollection(singleGeometry);
print('FeatureCollection from a single geometry', singleGeometryFc);

// FeatureCollection from a single feature.
var singleFeature = ee.Feature(ee.Geometry.Point(-62.54, -27.32), {key: 'val'});
var singleFeatureFc = ee.FeatureCollection(singleFeature);
print('FeatureCollection from a single feature', singleFeatureFc);

// FeatureCollection from a list of features.
var listOfFeatures = [
  ee.Feature(ee.Geometry.Point(-62.54, -27.32), {key: 'val1'}),
  ee.Feature(ee.Geometry.Point(-69.18, -10.64), {key: 'val2'}),
  ee.Feature(ee.Geometry.Point(-45.98, -18.09), {key: 'val3'})
