Hi,

I've tried both OSMTracker and OpenGPSTracker for Android to generate gpx files. On opening them with josm version 3966-1 I cannot see any waypoints, just the grey line of my track which is apparently uneditable.

Here a sample of my gpx file:

<gpx version="1.1" creator="nl.sogeti.android.gpstracker" xsi:schemalocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/gpx/1/1/gpx.xsd" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:gpx10="http://www.topografix.com/GPX/1/0" xmlns:ogt10="http://gpstracker.android.sogeti.nl/GPX/1/0"> <metadata> <time>2011-03-01T14:17:31Z</time> </metadata> <trk> <name>Track 2011-03-01 15:17</name> <trkseg> <trkpt lat="47.6107058" lon="10.6137722"> <ele>863.2999877929688</ele> <time>2011-03-01T14:17:36Z</time> <extensions> <gpx10:speed>1.1180340051651</gpx10:speed> <ogt10:accuracy>13.0</ogt10:accuracy> <gpx10:course>359.5</gpx10:course></extensions> </trkpt> . . .

If i remember right the OSMTracker generates two different files for waypoints and trackspoints, like YYYYMMDD_HHMMSS-wp.gpx and YYYYMMDD_HHMMSS-tp.gpx. Are you sure you haven't missed to transfer and open the wp.gpx-file in JOSM?

Apparently the gpx-file above has no waypoints because there are no wpt-entries in it.

Generally there is no problem to have both trackpoints and waypoints in the same gpx-file, but it's convenient to have them separated because then you can toggle them individually in JOSM.

JOSM creates separate layers for track and waypoints when reading in a GPX file containing both. It does that for me anyway.

I don't know Open GPS Tracker, but regarding editing GPS traces in JOSM, it can be done. Right-click the GPX trace layer, select "convert to data layer", and the trace can now be edited. To convert it back to GPX, right-click the layer and select either "convert to GPX" or "export to GPX".

Tongro, you got the gist of what I was trying to do and say - many thanks!

I remember trying that option before and shying away from it because of the warning it gives. This time I ignored it and, weyhey, it worked :)

Thank you for your quick answer.

Here is what I do: - stop tracking - select "share track" - send it to my email address

I've checked settings of both applications but do not see any reference to "waypoints" as such apart from how often I want to log my position. I double checked the files on my SD card and none of them have waypoints, only trackpoints!?

I've never used Open GPS tracker, but from the screen shots at http://code.google.com/p/open-gpstracker/wiki/ScreenShots i guess that the Make Note-button is the one that creates waypoints. Have you used that button, or why do you expect some waypoints to be in the export?

Take your tcx file from the garmin and convert it to gpx using http://www.gpsvisualizer.com/ and then it should load properly in JOSM
