ee.Geometry.MultiPoint.edgesAreGeodesics

  • edgesAreGeodesics() is a method used on MultiPoint geometries to determine the nature of its edges.

  • It returns true if the edges of the MultiPoint are treated as geodesics (curved lines along the Earth's surface), and false if they are treated as straight lines in the projection.

  • The method takes no arguments besides the geometry itself and returns a Boolean value.

  • This function is useful for understanding how Earth Engine interprets the edges of a MultiPoint when performing calculations or 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.

UsageReturns

Examples

Code Editor (JavaScript)

// Define a MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);

// Apply the edgesAreGeodesics method to the MultiPoint object.
var multiPointEdgesAreGeodesics = multiPoint.edgesAreGeodesics();

// Print the result to the console.
print('multiPoint.edgesAreGeodesics(...) =', multiPointEdgesAreGeodesics);

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