I'm getting involved, with minimal formal training, in a cartographic effort. A blind friend of mine is a Computer Science student at UT Austin. Using nothing but a white cane, she navigates half a mile of city and campus streets before arriving at the CS complex and going to the appropriate classroom. She has no maps for any of this journey.

I'd like to provide some tactile and/or audio maps for her, using as much mechanization as possible. See my follow-up post for details...
