Mapping

The OS Terms and Conditions require you agree to display certain text on their maps. I have added this text, but you have to agree not to remove it.

It may seem 'odd' but printing and using a map displaying the Copyright notice is legal, its removal is illegal. I am making many hours of my work available free of charge. Please note the copyright notice restricts people from selling my maps or removing the attribution box from the maps.
