NAME

GIS::Distance::Fast::Vincenty - C implementation of GIS::Distance::Vincenty.

DESCRIPTION

See GIS::Distance::Vincenty for details about this formula.

The results from GIS::Distance::Vincenty versus this module are slightly different. I'm still not sure why this is, as the C code is nearly identical to the Perl code.

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