ee.Geometry.toGeoJSON

  • toGeoJSON() converts an Earth Engine Geometry object into a GeoJSON representation.

  • This function takes a Geometry object as input and returns a GeoJSON Geometry object.

  • The provided examples demonstrate how to use this function in JavaScript and Python.

  • The GeoJSON output can be used for further processing or visualization in other geospatial tools.

Returns a GeoJSON representation of the geometry.

UsageReturns

Examples

Code Editor (JavaScript)

// Define a Geometry object.
var geometry = ee.Geometry({
  'type': 'Polygon',
  'coordinates':
    [[[-122.081, 37.417],
      [-122.086, 37.421],
      [-122.084, 37.418],
      [-122.089, 37.416]]]
});

// Apply the toGeoJSON method to the Geometry object.
var geometryToGeoJSON = geometry.toGeoJSON();

// Print the result to the console.
print('geometry.toGeoJSON(...) =', geometryToGeoJSON);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(geometry,
             {'color': 'black'},
             'Geometry [black]: geometry');
