ee.Geometry.toGeoJSONString

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

  • This function is useful for exporting geometry data for use in other geospatial tools and libraries that support GeoJSON.

  • The example code demonstrates how to use toGeoJSONString() in both JavaScript and Python environments within Google Earth Engine.

  • The returned GeoJSON string can be used to visualize or analyze the geometry data outside of the Earth Engine platform.

Returns a GeoJSON string representation of the geometry.

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

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 toGeoJSONString method to the Geometry object.
var geometryToGeoJSONString = geometry.toGeoJSONString();

// Print the result to the console.
print('geometry.toGeoJSONString(...) =', geometryToGeoJSONString);

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