ee.Geometry.BBox.edgesAreGeodesics

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

  • It returns true if edges are geodesics and false if they are straight lines.

  • This method is applicable to Geometry objects and can be accessed using the syntax geometry.edgesAreGeodesics().

  • The provided examples demonstrate its usage with a BBox (bounding box) geometry in both JavaScript and Python.

 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 BBox object.
var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43);

// Apply the edgesAreGeodesics method to the BBox object.
var bBoxEdgesAreGeodesics = bBox.edgesAreGeodesics();

// Print the result to the console.
print('bBox.edgesAreGeodesics(...) =', bBoxEdgesAreGeodesics);

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

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.
