- An implementation of co-ordinate conversion for England, Wales, and
- Scotland based on formulae and data published by the Ordnance Survey of
- Great Britain.
- These modules convert accurately between coordinates given in latitude
- and longitude and the OSGB national grid reference system (as used for
- maps of England, Wales, and Scotland).
- This code is fine tuned to the British national grid system. It is of
- no use outside Britain. In fact it's only really useful in the areas
- covered by the OS's main series of maps, which excludes the Channel
- Islands and Northern Ireland.
