Full Screen Maps and Tubewalk Planner
Posted by Mark Moxon on 15 May 2008
I’ve just added two new features to my tubewalk website, which you might find interesting.
The first is a full screen button for my route maps. Until now, you’ve only been able to view my route maps in a rather pokey manner, like this:
But not now! Simply click on the ‘Expand map’ link to expand the map to fill your browser window, and click on ‘Shrink map’ to go back again. Here’s an example of the same route in all its full screen glory.
The second new feature is a bit more interesting; it’s a tubewalk planner. Simply choose two Tube stations you’d like to walk between, and the planner will work out the shortest tubewalk from one to the other, showing you the distance in miles, how many stations you pass through, and a link to a route map. If you only choose one Tube station, then the planner will work out all possible routes starting (or ending) at that station. The planner is in its early stages, but it’s still fun to play with; the route above, which is from Amersham to Epping, is the kind of thing that the tubewalk planner can produce.
Oh, and for the technically minded out there, the planner uses Dijkstra’s algorithm to work out the shortest path between two points in the Tube network. I knew that computing degree would come in handy one day…
