NAME

Top

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

DESCRIPTION

Top

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

Top

GIS::Distance::Formula::Cosine::Fast

GIS::Distance::Formula::Haversine::Fast

GIS::Distance::Formula::Vincenty::Fast

BUGS

Top

The GIS::Distance::Formula::Vincenty::Fast produces slightly different results than GIS::Distance::Formula::Vincenty. Read the POD for GIS::Distance::Formula::Vincenty::Fast for details.
