p5-GIS-Distance

Calculate geographic distances

GIS::Distance calculates distances between geographic points on, at the moment, planet Earth. Various "FORMULAS" are available that provide different levels of accuracy versus speed. GIS::Distance::Fast, a separate distribution, ships with C implmentations of some of the formulas shipped with GIS::Distance. If you're looking for speed then install it and the ::Fast formulas will be automatically used by this module.
