not mentioned in that list is RoadMap (http://roadmap.sourceforge.net) which was designed for on-the-fly rendering on small devices. (a fork of RoadMap is what powers Waze, for instance.) RoadMap requires that you pre-convert quadtiles or other OSM subsets into its own .rdm format. it works reasonably, but would really be helped by a set of pre-converted maps on a public server. converting on the fly means hitting the OSM servers too much if you're downloading anything more than a pretty small area, and the bandwidth clamps cut in. i run roadmap using gtk, but it builds for qt, is being ported to android, and at one point even ran on the iphone. paul =--------------------- paul fox, [email protected] (arlington, ma, where it's 65.8 degrees) _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
