The Geodetic class can be used to calculate azimuths, distances, and Points on an Ellipsoid. It is inspired by the wonderful pyproj library.
def g = new Geodetic() def inverse = g.inverse(new Point(-71.1166666667,42.25), new Point(-123.6833333333,45.5166666667)) println inverse.forwardAzimuth -66.5304369615103 println inverse.backAzimuth 75.65384304860314 println inverse.distance 4164074.239295728
