ME! ME! ME! JOSM support this. ;-)

At least, if your data is in GPX. Use gpsbabel to convert it if necessary.

I habe been told several times now, that some user prefere to start with
the GPS-logs as node data and then start to strip out nodes until they

I think I will support this way of mapping with more tool coverage in one
of my next bigger releases. (e.g. Auto-deletion of unnecessary nodes
within a straight line, remove of nodes very close to each other etc...)

Currently you can open any GPX file and choose whether you want to import
it as raw gps trackpoints or as real Node data.

However, the quality of the result strongly depends on the format of your
input. If you have one big track covering a large journey, this would be
If you have some kind of the old OSM-export format, where every single
segment is contained in its own track, you will get exactly this: Numerous
tracks (which cannot be upload at present) you have to clean up with.
