ee.FeatureCollection.sort

  • The sort() method allows you to order a FeatureCollection based on the values of a specified property.

  • It takes the property name as a required argument and an optional boolean argument (ascending) to control the sort direction (ascending by default).

  • The method returns a new, sorted FeatureCollection without modifying the original.

  • Examples demonstrate sorting power plants by capacity in both ascending and descending order.
