---------------------------------------

             Summary: Gnomonic projection
                 Key: SIS-466
                 URL: https://issues.apache.org/jira/browse/SIS-466
             Project: Spatial Information Systems
          Issue Type: Sub-task
          Components: Referencing
            Reporter: Martin Desruisseaux


Implement the Gnomonic projection, where geodesics are straight lines. Formulas for the sphere
are given in Snyder. Formulas for the ellipsoid are impossible, but Charles F. F. Karney in
[Algorithms for geodesics (SRI International)|https://link.springer.com/content/pdf/10.1007%2Fs00190-012-0578-z.pdf]
gives a form where straight lines are very close to geodesics.
