NAME

       GIS::Distance::ALT - Andoyer-Lambert-Thomas distance calculations.

DESCRIPTION

       The ALT formula is intended as a much faster, but slightly less accurate, alternative of
       the GIS::Distance::Vincenty formula. This formulas is about 5x faster than Vincenty.

       The code for this formula was taken from Geo::Distance::XS and modified to fit.

       A faster (XS) version of this formula is available as GIS::Distance::Fast::ALT.

       Normally this module is not used directly.  Instead GIS::Distance is used which in turn
       interfaces with the various formula classes.
