ee.Geometry.Polygon.geodesic

Page Summary

• 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.

Usage	Returns
Polygon.geodesic()	Boolean

Argument	Type	Details
this: geometry	Geometry

Examples

// 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.

             {'color': 'black'},
             'Geometry [black]: polygon');
