ee.Geometry.MultiPolygon.toGeoJSONString

  • toGeoJSONString() returns a GeoJSON string representation of a MultiPolygon geometry in Earth Engine.

  • This function takes a Geometry instance as input and outputs a string containing the GeoJSON representation.

  • Code examples are provided in JavaScript, Python, and Colab demonstrating the usage of toGeoJSONString() with MultiPolygon geometries.

Returns a GeoJSON string representation of the geometry.

UsageReturns
MultiPolygon.toGeoJSONString()String
ArgumentTypeDetails
this: geometryGeometryThe Geometry instance.

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]]],

       [-122.086, 37.421],
       [-122.089, 37.416]]]]);

// Apply the toGeoJSONString method to the MultiPolygon object.
var multiPolygonToGeoJSONString = multiPolygon.toGeoJSONString();

// Print the result to the console.
print('multiPolygon.toGeoJSONString(...) =', multiPolygonToGeoJSONString);

// 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.
