Mapping the postal network Nick Hill has sent out a GPS to someone through the post… and left the unit switched on to track where it went:
How did the unit get a signal? Wasn’t it packaged, or did he just write the address on the unit’s screen with a speedmarker?
How did the unit get a sat fix? Can you send unwrapped items with Royal Mail? 😉
Nice experiment, but the zoomed out map there doesn’t really tell us much 🙂 Having the .gpx file would be more interesting.
