NAME

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

DESCRIPTION

This distribution re-implements some, but not all, of the formulas that come with GIS::Distance in the C programming language. C code is generally much faster than the perl equivilent.

In most of my testing I've found that the C version of the formulas outperform the Perl equivelent by at least 2x.

This module need not be used directly. GIS::Distance will automatically use the ::Fast formulas when they are available.

FORMULAS

GIS::Distance::Fast::Cosine

GIS::Distance::Fast::Haversine
