Geodetic (Groovy Documentation)

geoscript.proj.Geodetic

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
