Need more testing to find out what the root cause really is.

Investigation:

• GPX file can be successfully uploaded if all points are contained in same track segment.
• GPX file can be successfully uploaded if multiple tracks are in same file <trk>.
• GPX file gets platform error if multiple track segments <trkseg> exist within same <trk>.

OK

<trk>
    <trkseg>
        <trkpt>
        </trkpt>
    </trkseg>
</trk>

OK

<trk>
    <trkseg>
        <trkpt>
        </trkpt>
    </trkseg>
</trk>
<trk>
    <trkseg>
        <trkpt>
        </trkpt>
    </trkseg>
</trk>

NOT OK

<trk>
    <trkseg>
        <trkpt>
        </trkpt>
    </trkseg>
    <trkseg>
        <trkpt>
        </trkpt>
    </trkseg>
</trk>

Thanks for testing @clash99! @bjohare, do you think this would be something difficult to fix?

Here's the corresponding error log

[dpalomino]

We need to do some more research to know if this is a valid format, and how partner managed to have this GPX file. GPX file should not be modified in the way.

@bjohare can you please take a look, and see why this format is breaking the platform?

[clash99]

According to the GPX 1.1 spec, a track with multiple track segments is a correct format.

A Track Segment holds a list of Track Points which are logically connected in order. To represent a single GPS track where GPS reception was lost, or the GPS receiver was turned off, start a new Track Segment for each continuous span of track data.

If I upload the attached "broken" gpx file to a visualizer, I can see a path:

Thanks @clash99. It sounds to me like we need logic in Cadasta that connects the track segments if they are in track tags together.

[dpalomino]

Has to do with the specific format, @bjohare can you please take a look when you have a moment?

[SteadyCadence]

I get no error or map layer when I upload this file in staging:
convertToGPX.txt

• GH doesnt let me upload .gpx so I converted to .txt

I converted it from .gdb to .gpx in GPS Babel. Our partner in Thailand saves mostly in .gdb.... I think we will have to write a script to convert. It would be good to know what is accepted or not since the gpx doesnt seem to load.

Sounds like it works with @bjohare's changes! Awesome Sauce.
