Maps Formats Available and their Terms and Conditions

The standard Royal Observer Corp (ROC) nuclear monitoring post maps are printed on an U.K. outline map with a grid overlay. This makes it difficult to assimilate the locations of numbered spots with the physical layout of the towns and cities. When the Ordnance Survey made available a free base map, it opened up an opportunity to make a more meaningful map
Over a considerable period of time, I have plotted all the 837 mainland ROC Posts on an Ordnance Survey base map. Unfortunately the lack of a Northern Ireland base map means Belfast No.31 Group is plotted on an outline map only. I am making my efforts available free of charge, so that you may benefit too. In return, I ask that you don't sell my maps or remove the attribution box from the maps.
After plotting so many points, I can't guarantee they are without errors. If you do spot a typo, please get in touch so I may correct it. My contact details are on the Cold War Communications homepage. Use the menubar to Return to UKWMO Comms Website then click the Contact Me button.
