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;
