Subway Geography and Geometry
I've written an applet that lets you reimagine the geography of greater Washington, DC area with "distance" measured by subway-travel-time, measured by subway-travel-cost, or as the standard clarified subway wall map would deform it.
This was in large part inspired by Oskar Karlin's beautifully rendered Isochronic Elephant-Castle map of the London Underground and the interactive tube mapplet from Tom Carden.
Subway Maps of the world all on the same scale is pretty interesting, as is this directory of remixed London Underground maps. There's a few interesting images on wiki commons, like this geographical map within this gallery.
Also, you can download the image files (very large, register with each other) from Wikipedia:
- Greater Washington, DC Area: Road Map
- Greater Washington, DC Area: Topological Map
- Greater Washington, DC Area: Aerial Photo
