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 equivalent.

See "SPEED" in GIS::Distance for some benchmarking and how to run your own benchmarks.

This module need not be used directly. GIS::Distance will automatically use the "GIS::Distance::Fast::*" formulas when installed.

FORMULAS

GIS::Distance::Fast::Cosine
GIS::Distance::Fast::GreatCircle
GIS::Distance::Fast::Haversine
GIS::Distance::Fast::Polar
GIS::Distance::Fast::Vincenty
