NAME ^

Geo::Coordinates::ITM - Convert coordinates between lat/lon and Irish Transverse Mercator

VERSION ^

This document describes Geo::Coordinates::ITM version 0.02

SYNOPSIS ^

  use Geo::Coordinates::ITM qw( ll_to_grid grid_to_ll );

  my ( $lat, $lon ) = grid_to_ll( $east, $north );
  my ( $east, $north ) = ll_to_grid( $lat, $lon );

DESCRIPTION ^

Convert back and forth between Irish Transverse Mercator grid and WGS84. The conversion code was stolen wholesale from http://bit.ly/ZqpUA.

  my ( $east, $north ) = ll_to_grid( $lat, $lon );

grid_to_ll

Convert an ITM easting, northing pair to a WGS84 latitude, longitude.

  my ( $lat, $lon ) = grid_to_ll( $east, $north );
