JOSM is able to work with local GPX files. But of course, you'd have to open each one individually and as you say each one is rather low density. So what you'd probably have to do to make it practical is re-process the GPX files into "tiles" each covering a certain area and only open up GPX files corresponding to the areas you're about to edit. You could build up the road network in JOSM this way. And you wouldn't even have to build the whole city and do a massive upload - you could work incrementally. robert. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
