NAME

GIS::Distance::Lite - Calculate geographic distances between coordinates in geodetic WGS84 format.

SYNOPSIS

  use GIS::Distance::Lite qw(distance);
    
  my $distanceInMeters = distance($lat1, $lon1 => $lat2, $lon2);

DESCRIPTION

The module provides a method to calculate geographic distances between coordinates in geodetic WGS84 format using the Haversine formula.

It is similar to GIS::Distance, but without the extra bells and whistles and without the additional dependencies. Same great taste, less filling. It exists for those who cannot, or prefer not to install Moose and its dependencies.

my $distanceInMeters = GIS::Distance::Lite::distance($lat1, $lon1 => $lat2, $lon2);

Calculate distance between two set of coordinates.

Parameters:

 $latitude1  (number)
 $longitude1 (number)
 $latitude2  (number)
 $longitude2 (number)

Example:

 my $distanceInMeters = GIS::Distance::Lite::distance(59.26978, 18.03948 => 59.27200, 18.05375);

Returns:

the distance in meters;
