ee.Geometry.LinearRing.geodesic

  • Edges in the projection are straight if geodesic() returns false and curved to follow the shortest path on the Earth's surface if it returns true.

  • The LinearRing.geodesic() method returns a Boolean value.

  • The geodesic() method can be applied to a LinearRing geometry object in both JavaScript and Python.

 If false, edges are straight in the projection. If true, edges are curved to follow the shortest path on the surface of the Earth.

Examples

Code Editor (JavaScript)

// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Apply the geodesic method to the LinearRing object.
var linearRingGeodesic = linearRing.geodesic();

// Print the result to the console.
print('linearRing.geodesic(...) =', linearRingGeodesic);

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