OpenStreetMap
Recently I bought my first GPS device. I got a Garmin Vista HCx, so I can upload the Garmin format map made by Cloudmade, and the electronic compass seems like a cool gimmick even if not that useful. I still went out and mapped in the usual way, by printing out the NoName map and taking notes, but the GPS track gives a useful check that any newly added streets and paths are in the right place. Next time I'll get more advanced and mark waypoints, but yesterday it was too cold to be pressing buttons with my hands.
The trace is here and I particularly used it to map a new housing development here . I was pleased to see that the roads and paths I had guessed before without using GPS mostly lined up with the real world.
When I uploaded my trace, however, I got an error message back from the site:
loaded successfully with 2583 out of a possible 3992 points. Of the failed points, 1409 lacked
Is this normal for gpx files generated from a Garmin device? Should I do something to add the missing
(For editing I use Merkaator which can load the traces directly, but I like to upload the traces to the server to keep a record.)

I have a Garmin Vista HCx and have uploaded lots of traces collected with it without an error.

Do you have any 'saved' tracks on the Garmin?
They don't have timestamps. Saving tracks on a Garmin is very much to be avoided.

I've had a quick look at your trace - and the first part of your trace has trackpoints without any timestamp - which will be rejected. The rest looks fine - and looks like what I get from my Vista when I write tracks to the microSD card.
Looks likely that the first set of points have been saved as the other Richard said - which strips the timestamps out.
You could put dummy timestamps on these points using something like a text editor or a spreadsheet even. Apparently the "sendmap" program can do this as well - although I don't use it myself. Once you've done that, the rest of the points should be accepted by the server.
