Plus, you could end up with a lot of garbage and noise. I carry my GPS with
me a lot, and I'm usually not dedicated to mapping, so I get a lot of
spurious tracks. I'm going through right now and cleaning up my tracks,
cutting out clusters of points where I stopped, etc. If people upload their
raw tracks and they go directly into the server, that will eliminate the
chance for the tracks to be cleaned up. However, I guess you could say the
sort of people that need to upload raw tracks to a server to be translated
are not going to be the sort that are inclined to edit their tracks...
That's sort of another point--I've already seen a bunch of junk "noisy"
tracks in my area. It would be nice if there were a way to remove/filter
them. I could create a tracklog that wrote "Hi Mom" or some other less
innocent graffiti in GPX and upload it and nobody but the admins would be
able to fix/remove it.
