ee.FeatureCollection.distinct

  • Thedistinct method removes duplicate elements from aFeatureCollection.

  • Duplicates are identified by creating a strong hash of the serialized selected properties.

  • The method accepts a property name or a list of property names for comparison, including the.geo property for geometry comparison.

 Removes duplicates from a collection. Note that duplicates are determined using a strong hash over the serialized form of the selected properties.

UsageReturns
FeatureCollection.distinct(properties)FeatureCollection
ArgumentTypeDetails
this:collectionFeatureCollectionThe input collection from which objects will be selected.
propertiesObjectA property name or a list of property names to use for comparison. The '.geo' property can be included to compare object geometries.

Examples

Code Editor (JavaScript)

// FeatureCollection of power plants in Belgium.varfc=ee.FeatureCollection('WRI/GPPD/power_plants').filter('country_lg == "Belgium"');print('FeatureCollection of power plants in Belgium',fc);// Remove duplicate features according to property values.print('Distinct based on a single property',fc.distinct('fuel1'));print('Distinct based on two properties',fc.distinct(['fuel1','source']));print('Distinct based on geometry',fc.distinct('.geo'));
