ee.Geometry.MultiPolygon.geodesic

Page Summary

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

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

• The method takes a geometry argument of type Geometry.

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
MultiPolygon.geodesic()	Boolean

Argument	Type	Details
this: geometry	Geometry
