ee.Geometry.Point.edgesAreGeodesics
Stay organized with collections
Save and categorize content based on your preferences.
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.
| Usage | Returns | Point.edgesAreGeodesics() | Boolean |
| Argument | Type | Details | this: geometry | Geometry | |
Examples
Code Editor (JavaScript)
// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);
// Apply the edgesAreGeodesics method to the Point object.
var pointEdgesAreGeodesics = point.edgesAreGeodesics();
// Print the result to the console.
print('point.edgesAreGeodesics(...) =', pointEdgesAreGeodesics);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(point,
{'color': 'black'},
'Geometry [black]: point');
