Geo::Coordinates::ITM3pm
Convert coordinates between lat/lon and irish transverse mercator
Usage
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 );
Version

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 );
