Examples of orthodromicDistance()

org.geotools.referencing.datum.DefaultEllipsoid.orthodromicDistance()
Returns the orthodromic distance between two geographic coordinates. The orthodromic distance is the shortest distance between two points on a sphere's surface. The default implementation delegates the work to {@link #orthodromicDistance(double,double,double,double)}. @param P1 Longitude and latitude of first point (in decimal degrees). @param P2 Longitude and latitude of second point (in decimal degrees). @return The orthodromic distance (in the units of this ellipsoid).

             * We should probably revisit the way we compute distances.
