# Geo::Coordinates::ITM(3pm)

Convert coordinates between lat/lon and Irish Transverse Mercator

## 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\>.

```
  http://svn.geograph.org.uk/svn/branches/british-isles/libs/geograph \
    /conversionslatlong.class.php
```

Nothing is exported by default. The exportable functions are `"ll_to_grid"` and `"grid_to_ll"`.

## INTERFACE

### "ll\_to\_grid"

Convert a latitude, longitude (WGS84) coordinate pair into an ITM easting and northing.

```
  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 );
```
