ee.Geometry.MultiPolygon.toGeoJSON

Page Summary

• The toGeoJSON() method returns a GeoJSON representation of a geometry.

• This method is used on a MultiPolygon geometry instance.

• The method takes the geometry instance itself as an implicit argument.

• Examples are provided for both JavaScript and Python to demonstrate the usage of the toGeoJSON() method and visualize the result.

Returns a GeoJSON representation of the geometry.

Usage	Returns
MultiPolygon.toGeoJSON()	GeoJSONGeometry

Argument	Type	Details
this: geometry	Geometry	The Geometry instance.

// Define a MultiPolygon object.

// Apply the toGeoJSON method to the MultiPolygon object.
var multiPolygonToGeoJSON = multiPolygon.toGeoJSON();

// Print the result to the console.
print('multiPolygon.toGeoJSON(...) =', multiPolygonToGeoJSON);

// Display relevant geometries on the map.

             {'color': 'black'},
