[OSM-talk] clean gpx tracks

[Gert Gremmen]

That is exactly why i stopped uploading tracks a long time
ago.
If any query rises about the authenticity of any track
I have drawn, the history will show where any justification can be
found.
Then, I will or will not hand over any of my GPS tracks.

It's not because ANYONE including Steve decided this at the beginning
of a project that it should not be liable to discussion about
it's use.

That is why we want all the tracks that we can get so anybody trying 
to 'infect' the data with copyrighted material doesn't have a hope in
hell 
since there is so much more from non copyright sources.

I really don't get this. Although I am not a programmer I find it very
hard to 
believe that the 'importer' cannot be changed to accept tracks without
time 
stamp data.
O.k. so the decision was made at a very early stage, so that is why
there is 
no real record of it. But if it is a bad decision (with hindsight of
course 
and under different circumstances: geotagged photos, Yahoo imagery
etc)), 
that is to say it has negative effects, it seems only logical to change
it.

What I personally want is to upload clean data because it helps me as a
mapper 
when there is as little noise as possible in the gps data. So therefore
I 
don't want to burdon others with my noisy data.
I want to upload my tracks because when I enter data I like every bit of

confirmation that my data is good, that I can get. Obviously if I like
others 
to upload their tracks I need to upload mine, that's the basis of why a 
project like this works! 

If I could cut out the garbage out of my tracks as easily as I can in
Josm but 
without destroying the timestamp info the issue that triggered this
'quest' 
would be gone (or rather would not even have come up).

However the other issues I hadn't thought about before remain.
If people are not uploading their tracks because of privacy issues it is
a 
loss to everyone. 

The question with any 'rule' always remains: is it useful, is it adding
or 
taking away?

Absolutely, common sense approach is best!
