ee.Geometry.LineString.geodesic

  • The geodesic() method of a LineString object returns a Boolean value indicating whether the edges are curved to follow the shortest path on Earth's surface or straight in the projection.

  • If geodesic() returns false, edges are straight in the projection; if true, edges are curved to follow the shortest path on the Earth's surface.

  • The method is applied to a Geometry object and takes no arguments.

  • The provided examples demonstrate applying geodesic() to a LineString in both JavaScript and Python and printing or displaying the resulting Boolean value.

 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 LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Apply the geodesic method to the LineString object.
var lineStringGeodesic = lineString.geodesic();

// Print the result to the console.
print('lineString.geodesic(...) =', lineStringGeodesic);

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

Python setup

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

Colab (Python)

# Define a LineString object.
linestring = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]])

# Apply the geodesic method to the LineString object.
linestring_geodesic = linestring.geodesic()

# Print the result.
