ee.Geometry.LineString.edgesAreGeodesics

  • TheedgesAreGeodesics() method returns a boolean indicating whether the geometry edges are geodesics along a spherical Earth model or straight lines in a projection.

  • The method is applied to aLineString object and returns a Boolean value.

  • Examples are provided in both JavaScript and Python demonstrating how to use theedgesAreGeodesics() method.

 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
LineString.edgesAreGeodesics()Boolean
ArgumentTypeDetails
this:geometryGeometry

Code Editor (JavaScript)

// Define a LineString object.varlineString=ee.Geometry.LineString([[-122.09,37.42],[-122.08,37.43]]);// Apply the edgesAreGeodesics method to the LineString object.varlineStringEdgesAreGeodesics=lineString.edgesAreGeodesics();// Print the result to the console.print('lineString.edgesAreGeodesics(...) =',lineStringEdgesAreGeodesics);// Display relevant geometries on the map.Map.setCenter(-122.085,37.422,15);Map.addLayer(lineString,{'color':'black'},'Geometry [black]: lineString');
