Military Base only
The map shows the locations of airfields and weather stations. There will be a layer that has a 2 mile radius around each airfield which designates the 30m (100 feet) restriction. In the case of the larger international airports I shall extended that to 3 or 4 miles depending on the location. This is just to give you an idea. I am going to include a geolocation facilty for mobile devices. Use the slider to fade between Google and Ordnance Survey mapping. Temporary Height Restriction Map.
