I have been tasked to do a map for the vision-impaired. At first I thought, "simple, I'll just place locale names (text) spatially, and they can print it out in braille."

But as I ask questions, I realize they want to know what the terrain is like - that's way harder to do. At this point, I am thinking making a map similar to how pictures were done back in 'the old days' with dot-matrix printers: use text to 'draw' the map.

Has anyone ever tried this? Anyone have any good ideas?
