NAME

GIS::Distance - Calculate geographic distances.

SYNOPSIS

use GIS::Distance;
my $calc = GIS::Distance->new();
my $distance = $calc->distance( $lon1,$lat1 => $lon2,$lat2 );

DESCRIPTION

This perl library aims to provide as many tools to make it as simple as possible to calculate distances between geographic points, and anything that can be derived from that.

METHODS

new

my $calc = GIS::Distance->new();

Returns a blessed GIS::Distance::Haversine object by default. If you want to use a different formula, such as the GIS::Distance::Vincenty, then call new() on that class.

distance

my $distance = $calc->distance( $lon1,$lat1 => $lon2,$lat2 );

Calculates the distance between two lon/lat points in decimal degree format. In return you will receive an Class::Measure::Length object.
