ee.FeatureCollection.getNumber

    • Learn how to extract a numerical property from a FeatureCollection using the getNumber method.

    • The getNumber method takes the property name as a string and returns an ee.Number object in JavaScript or requires .getInfo() in Python for a standard number.

    • Examples in both JavaScript and Python demonstrate how to apply getNumber to retrieve a specific number property from a FeatureCollection.
