ee.Geometry.LinearRing.geodesic

  • LinearRing.geodesic() is a method in Earth Engine that determines whether the edges of a LinearRing object are rendered as straight or curved.

  • If geodesic() returns false, edges appear straight in the projection; if true, edges are curved to follow the shortest path on the Earth's surface (geodesic).

  • This method can be applied to LinearRing geometries to control their visual representation on the map.

 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');
