Examples
// Define a MultiPolygon object.
var multiPolygon = ee.Geometry.MultiPolygon(
[[[[-122.092, 37.424],
[-122.086, 37.418],
[-122.079, 37.425],
[-122.085, 37.423]]],
[[[-122.081, 37.417],
[-122.086, 37.421],
[-122.089, 37.416]]]]);
// Apply the geometries method to the MultiPolygon object.
var multiPolygonGeometries = multiPolygon.geometries();
// Print the result to the console.
print('multiPolygon.geometries(...) =', multiPolygonGeometries);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPolygon,
{'color': 'black'},
'Geometry [black]: multiPolygon');
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.
