I am stoked to see Roadster showing a bit of action. Way to go Jeff! On 9/8/07, Carl Worth <[EMAIL PROTECTED]> wrote: > * New "database".

Carl, didn't you (or somebody) come up with a strong database specification a year or two ago? > * Keep things light enough for a small, embedded device.

I'll buy one the instant they get that GPS working well. > * Of course, routing computation would be really useful. Getting > sufficient data is the hardest part, (how much does TIGER have > with respect to connections, one-way streets, illegal turns, speed > limits, etc?. anything?). Not really. I played around with routing via Tiger when I was living in Boston (admittedly, one of the more difficult American cities to route) and found utter failure. Wrong way down one-way streets, jumping from highway to city streets without an exit, ignoring expressways, taking very roundabout paths, etc. It was dismal. http://openstreetmap.org would be an excellent, collaborative way to fix this but it will take a *long* time and there seems to be very little interest in the U.S. (incidentally, what database format does OSM use?) I was toying with the idea of writing a program that would find identical routes on any of the big maps (Google, Yahoo, etc -- they all use Navteq) and Tiger to find specific areas where Tiger is deficient. Tempting, but I'd probably have to keep it on the DL since -- even if I only used the results to show areas that need to be fixed and didn't copy any data -- it probably violates their acceptable use policies. And, given my time lately, there's not much danger of my ever getting around to this. *sigh* _______________________________________________ roadster mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/roadster
