ee.FeatureCollection.get
Extract a property from a feature.
Usage | Returns |
---|
FeatureCollection.get(property) | |
Argument | Type | Details |
---|
this: object | Element | The feature to extract the property from. |
property | String | The property to extract. |
Examples
// 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
# 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())
