Yes, I can see that. It would take a significant effort in software design. However, it would greatly reduce the amount of effort for getting data into a useful form. The current OSM method seems very tedious. >Perhaps your assumptions about how you thought things were going to >work made things seem more difficult than they really are. I have been working with JOSM trying to find a way of putting an acceptable amount of effort into converting GPX tracks into OSM ways. So far I have found the software to not especially facilitate the task. I have about 7 miles of tracks which I hand culled and I still only have about a mile of that in OSM. Actually, I have not been able to verify that the data has been entered since I can't access the map page. It keeps timing out at the moment. If I can't get JOSM to work well, I might just work on a program to automatically convert GPX to OSM format. The mass processing of multiple collected data sets may not be currently feasible, but JOSM just requires too much hand work. It would take many hours for me to make a useful contribution this way and I just don't have the time. But I am not done trying JOSM yet. We'll see how that goes once things are back up at the web site. _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/newbies
