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 );

  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 );
