Mapping

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 Main Site Chapter Index then click the Home Page & Contact Me button.

A range of maps are encapsulated within a PDF files for ease of printing. The group maps are centred on one group and usually show parts of surrounding groups too. Open the PDF directly in your browser, but its better to save a copy to disk and print it later as Adobe Acrobat offers a wider range of printing options not always found in browser's viewers.
