ee.Geometry.Rectangle.edgesAreGeodesics

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

  • Returns true if edges are geodesics, indicating they follow the Earth's curvature; returns false if edges are straight lines.

  • Applicable to Rectangle geometries in Earth Engine.

  • 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.

UsageReturns
Rectangle.edgesAreGeodesics()Boolean

this: geometryGeometry

Examples

Code Editor (JavaScript)

// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);

// Apply the edgesAreGeodesics method to the Rectangle object.
var rectangleEdgesAreGeodesics = rectangle.edgesAreGeodesics();

// Print the result to the console.
print('rectangle.edgesAreGeodesics(...) =', rectangleEdgesAreGeodesics);

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