i guess i didn't emphasize how small the .rdm files are. i loaded up maps (admittedly they were Tiger-based, not OSM-based, but the compiled form isn't much different in either case) for a road trip this past weekend. all of MA, RI, CT, NY, NJ, and PA occupied 275MB. i just tried a download and conversion of all 25bit quadtiles covering a 20mi radius centered on 34.15,-118.348 (i.e., los angeles), and while i was cut off by the bandwidth limiter eventually, it looks pretty complete and only takes 11M on disk. there are certainly rough edges: the label placement code works on a quadtile-by-quadtile basis, so name placement collisions occur pretty frequently when you're using small quadtiles like that (i think 25 bit quadtiles are only 4.8km on a side). so bigger quadtiles would be better. and roadmap doesn't know how to label points -- just lines and areas. (plus, currently, the developer community is very small -- like just two people, and i'm not even very active, currently.) paul =--------------------- paul fox, p...@foxharp.boston.ma.us (arlington, ma, where it's 66.9 degrees)
