Earth Engine is introducing noncommercial quota tiers to safeguard shared compute resources and ensure reliable performance for everyone. All noncommercial projects will need to select a quota tier by April 27, 2026 or will use the Community Tier by default. Tier quotas will take effect for all projects (regardless of tier selection date) on April 27, 2026 . Learn more.

ee.Geometry.edgesAreGeodesics

Page Summary

The Geometry.edgesAreGeodesics() method returns a boolean indicating if the geometry edges are geodesics on a spherical Earth model or straight lines in a projection.
This method takes a Geometry object as input.
The examples demonstrate how to use this method in both JavaScript and Python to check the geodesic property of geometry edges and display 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.

Usage	Returns
`Geometry. edgesAreGeodesics ()`	Boolean

Argument	Type	Details
this: `geometry`	Geometry
