converting module between Lat/Lon and the British National Grid

The included modules provide an implementation of co-ordinate conversion for England, Wales, and Scotland based on formulae and data published by the Ordnance Survey of Great Britain.

The Geo::Coordinates::OSGB module provides routines to convert between latitude/longitude coordinates in the WGS84 or OSGB36 models and the British National Grid. The Geo::Coordinates::OSGB::Grid module includes some useful extra routines to parse and format grid references in a variety of popular forms (including which Landranger map your point appears on). The Geo::Coordinates::OSGB::Maps module provides data for British maps.

Note that due to the nature of this type of conversion, the conversions are only really useful in the vicinity of the British Isles. If you are elsewhere on the planet you need an implementation optimized for your neighbourhood.
