If I Alt Click a track to make it a way, is it supposed to have the same amount of points as the original gpx? My hiking tracks are recorded at 3 sec. intervals, and look fine in Mapsource. However, once uploaded to OSM they seem to lack resolution. Is what I am seeing typical for an upload? This question is marked "community wiki". asked 08 Jun '12, 00:00  zeeland5 |
One Answer:
GPS traces are not suited for direct upload to OSM as already mentioned by SomeoneElse. They usually contain too many points and simply converting them to a way doesn't create the required junctions/connections with surrounding ways. You should always create the way by yourself, adding points where necessary and omitting points when the way is just straight. The Wiki has multiple pages about processing GPS traces:

Not an answer to your question, but one thing that is worth mentioning is that you probably don't want to have quite as many nodes in a way as one-every-3-seconds-at-walking-pace would give you (especially if you're walking in a straight line).
