AI-generated Key Takeaways
-
The
edgesAreGeodesics()method returns true if the geometry edges are geodesics along a spherical Earth model, and false if they are straight lines in the projection. -
The method is applied to a
Geometryobject and returns a Boolean value. -
Examples are provided in both JavaScript and Python demonstrating how to use the method with a
MultiPolygon.
