ee.Geometry.Polygon.edgesAreGeodesics

  • TheedgesAreGeodesics() method returns true if the geometry edges are geodesics along a spherical Earth model, and false if they are straight lines in the projection.

  • This method is used on aGeometry object and returns a Boolean value.

  • The provided examples demonstrate how to useedgesAreGeodesics() with aPolygon object in both JavaScript and Python.

  • The code examples show defining a polygon, applying the method, printing the result, and displaying the geometry on a map.

 Returns true if the geometry edges, if any, are geodesics along a spherical model of the earth; if false, any edges are straight lines in the projection.

UsageReturns
Polygon.edgesAreGeodesics()Boolean
ArgumentTypeDetails
this:geometryGeometry
