[OSM-talk] clean gpx tracks

[Lambert Carsten]

Hi,

I tried to upload a couple of gpx tracks that I had cleaned up with Josm. They 
were refused with a message that seems to suggest thy are missing time stamps 
(possibly missing altitude).

Why does openstreetmap want timestamps? There is no reason for this.
I want to clean up my tracks to prevent uploading garbage from when I forgot 
to switch off my logger. I know in time (in theory at least) the garbage will 
be lost as noise behind good data. But where I collect data (mostly 
Amsterdam) there is already so much garbage and bad tracks in many area's 
rendering those tracks useless. In other area's there are no tracks at all 
and and these are exactly the area's I am trying to locate and track. Also I 
hope by adding more good tracks the balance will tip in favor of the good 
data. 
What is the reasoning here?

There is also a privacy advantage not uploading the unnecessary time stamps. I 
am sure there are many that hesitate to upload tracks for privacy reasons. 
If the problem is with the missing altitude: some of my original trackpoints 
had an altitude of of over 6km in the Netherlands!!

I can solve my problem by not uploading my tracks anymore and just use them 
personally to enter osm data. At least with my own tracks I know which bits 
are good, which are so so and which bits are bad. But I thought the whole 
point was to share all this data.

Maybe someone can point me to some editor with which I can easily clean up the 
tracks without clearing out the time stamps (personally I don't have a 
problem uploading that info).
