Code Editor (JavaScript)Colab (Python)

// An empty FeatureCollection for simple demonstration.
var fc = ee.FeatureCollection([]);

// Set a single new property using a key-value pair.
fc = fc.set('key_1', 'value 1');

// Set multiple new properties using a series of key-value pairs.
fc = fc.set('key_2', 'value 2',
            'key_3', 3);

// Set new properties using a dictionary of key-value pairs.
fc = fc.set({
  key_5: ee.Array([1, 2, 3]),
  key_6: ee.Image(0),
  key_7: ee.Feature(null)
});
print('New FeatureCollection properties added', fc);

// Overwrite an existing property.
fc = fc.set('key_1', 'overwritten');
print('FeatureCollection property overwritten', fc);
