ee.Geometry.MultiLineString.geodesic

  • The geodesic() method determines whether edges of a MultiLineString are rendered as straight lines or curved to follow the Earth's curvature.

  • It returns true if edges are curved (geodesic) and false if they are straight.

  • This method can be applied to a MultiLineString object to control its visual representation on a map.

  • The method does not alter the underlying geometry; it only affects its display.

If false, edges are straight in the projection. If true, edges are curved to follow the shortest path on the surface of the Earth.

Examples

Code Editor (JavaScript)

// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the geodesic method to the MultiLineString object.
var multiLineStringGeodesic = multiLineString.geodesic();

// Print the result to the console.
print('multiLineString.geodesic(...) =', multiLineStringGeodesic);

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