ee.Geometry.LinearRing.edgesAreGeodesics

  • The edgesAreGeodesics() method determines if a geometry's edges are modeled as geodesics (curves along the Earth's surface) or straight lines in the projection.

  • It returns true if edges are treated as geodesics on a spherical Earth model; otherwise, it returns false, indicating straight-line edges.

  • This method is specifically applicable to LinearRing geometries in Earth Engine.

  • The method can be used to understand how a geometry's edges are interpreted in calculations and visualizations.

 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.

Examples

Code Editor (JavaScript)

// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Apply the edgesAreGeodesics method to the LinearRing object.
var linearRingEdgesAreGeodesics = linearRing.edgesAreGeodesics();

// Print the result to the console.
print('linearRing.edgesAreGeodesics(...) =', linearRingEdgesAreGeodesics);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(linearRing,
             {'color': 'black'},
             'Geometry [black]: linearRing');
