I've been look into a 300+km state highway here that is not currently mapped. If I look at the area in Josm there is a trace that has been uploaded that has resolution good enough to see the individual lanes on the 2 lane highway (I think the traces came from national road agency surveying). This is in an area where there almost no other traces or existing mapping except coastline.
On advice of the helpful people on irc I tried using the 'convert to data layer' option in JOSM but it seems to get confused by the 5k trackpoint chunks that are supplied by the api. Instead of giving a way that connects nodes in order like 1->2->3->4 etc you get a way that seems to go something like 1->5000->2->5001->3 etc. It works if I do it in small enough areas but by the time I filter out other trace points and tidy up its not much faster than tracing. Is there a way to identify the trace or the user who uploaded it assuming it was uploaded as public, apart from trying to guess tags? If I had the original trace it would make the job of converting, simplifying and editing into existing data much quicker. I pretty sure there is quite a few more highways in the same condition which would mean a LOT of tracing unless I can find a better way. cheers rcr _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
