There’s usually a lot of manual labor involved in designing these maps, but they’re also an obvious candidate for automated layout attempts. I wouldn’t waste my time trying (and failing) to invent some algorithm, as more brilliant people before me have done so much better than I could, but I am interested in implementing one for some sort of tool that can be fed a KML or other geodata and spit out a simple metro map-like diagram.<\/p>\n
I’m currently in the early stages of working through the method devised by Jonathan Stott<\/a> for his Ph.D. thesis (25 MB PDF<\/a>).<\/p>\n Above is some early progress on a single subway line, a branch of the Red Line of Boston’s MBTA (or “T” if you like). It’s not great yet, but I’m not done yet. (Gotta get rid of those 90-degree turns!) In the end I’m hoping that I’ll be able to produce a map of any network of lines and nodes, be it a subway system, roads, or what have you. Stay tuned, and I’ll post when I have made some actual progress.<\/p>\n <\/p>\n Speaking of transportation, the other mini-project is to keep track of everywhere I go and the mode of transportation to get there. I’m not carrying a GPS receiver everywhere, but I do keep unreasonably detailed memories of all my travel paths (at least for a short time). I’m hoping that after a while this map might be mildly interesting because 1) I work from home, so my trips are somewhat irregular in both timing and destination, and 2) my movement around town is pretty multimodal.<\/p>\n Here’s most of my January so far. (Green: by foot, Purple-ish: by car, Blue: by bus, Black: by subway)<\/p>\n Hoping this will make for a sweet animation after some months. But you’re right; it’s probably stupid.<\/p>\n","protected":false},"excerpt":{"rendered":" Two ongoing things are keeping me entertained in my spare time these days.
