GPS Mapping....old style
Strange Maps Blog reports that:
Satellite navigation (SatNav) is considerably older than previously thought, older than man-made satellites in fact. Depicted above is a device called the ‘Routefinder’, a 1920s version of the contemporary GPS system in high-end automobiles.
Using the Routefinder, drivers in the UK manually scrolled through the roads they were travelling, providing them with mileage statistics and the journey’s end. This early 20C technology quaintely consisted of a tiny map scrolled inside a watch, worn by the driver as he/she travelled along on the map. A "trip-tik" of scrolls would be inserted into the watch to customize the planned route of travel.
