ee.Geometry.Polygon.geodesic

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

  • If true, edges are curved to follow the shortest path on the surface of the Earth.

  • If false, edges are straight in the projection.

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

UsageReturns
Polygon.geodesic()Boolean

Examples

Code Editor (JavaScript)

// Define a Polygon object.
var polygon = ee.Geometry.Polygon(
    [[[-122.092, 37.424],
      [-122.086, 37.418],
      [-122.079, 37.425],
      [-122.085, 37.423]]]);

// Apply the geodesic method to the Polygon object.
var polygonGeodesic = polygon.geodesic();

// Print the result to the console.
print('polygon.geodesic(...) =', polygonGeodesic);

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