ee.FeatureCollection.get

  • The get() method is used to extract a specific property from a Feature or FeatureCollection in Earth Engine.

  • The propertyNames() method provides a list of all property names associated with a Feature or FeatureCollection.

  • The value returned by get() is an ee.ComputedObject and might need to be cast to a specific Earth Engine object type for further processing.

  • The provided examples demonstrate how to access and utilize the extracted property value in both JavaScript and Python environments.

 Extract a property from a feature.

UsageReturns

Examples

Code Editor (JavaScript)

// A global power plant FeatureCollection.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants');

// View a list of FeatureCollection property names.
print(fc.propertyNames());

// Get the value of a listed property.
print('Global power plant data provider as ee.ComputedObject',
      fc.get('provider'));

// The returned value is an ee.ComputedObject which has no methods available for
// further processing; cast to the relevant Earth Engine object class for use.
print('Global power plant data provider as ee.String',
      ee.String(fc.get('provider')));

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

# A global power plant FeatureCollection.
fc = ee.FeatureCollection('WRI/GPPD/power_plants')

# View a list of FeatureCollection property names.
print(fc.propertyNames().getInfo())

# Get the value of a listed property.
print('Global power plant data provider as ee.ComputedObject:',
      fc.get('provider').getInfo())

# The returned value is an ee.ComputedObject which has no methods available for
# further processing; cast to the relevant Earth Engine object class for use.
print('Global power plant data provider as ee.String:',
      ee.String(fc.get('provider')).getInfo())
