Time Shift. A very British Map: Ordnance Survet.
by H&BI have just watched a wonderful BBC4 program about mapping great Britain from the very first hand drawn Ordnance Survey maps what we all call an Os map up to the very latest machine printed ones. From how they are calculated and measured with theodolite and tape measures. The program is on the BBC iPlayer.
