Underground
I’d always wanted to see what an underground map would look like and the other day I remembered whilst infront of the computer. Now, the one I have below is not totally accurate insofar as exactly where the tubes are laid, but it is more so as far as the stations sit. This map was generated as part of the London Underground geographic maps project by software written by ed g2s and James D. Forrester utilising GPS data.
