British Ordnance Survey Clip from 1953

I ran across this all-to-brief, but highly entertaining 1953 film of cartographic history, brought to us courtesy of the British Ordnance Survey. Perhaps an early excample of the use of computers in mapping, the clip documents some of the steps Ordnance cartographers employed to keep up with the hectic pace of mapping the quickly changing British countryside. It’s the first I’ve ever heard tell of a “tellurometer“.
