Invalid GPS coordinates on GoPro 6 - coords completely off track

Open highsource opened this issue 7 years ago • 0 comments

Please see #27 for the background information.

A further problem I'm facing are coordinate which are completely off track.

BIN file:

GX010039.bin.zip

This is the GPX track I'm getting:

GX010039.gpx.zip

The tracks looks "exploded" in a few places:

qgis-1

This part here is completely off the track. Quite sure I did not drive there:

qgis-4

Same here:

qgis-3

Check the "vertical" part here in the middle. Looks quite consistent. Except there's no road there and I did not drive there. Also consider the part in the upper right corner.

qgis-3

Also get severely inprecise coordinates along the track:

qgis-2

Quik shows a somewhat better looking track:

quik

However Quik does not show almost the half of the drack I actually drove.

I don't think these "explosions" of the track can't be explained by the imprecision of GPS. Ok, I'm fine with a few meters, but I see jumps of several hundreds meters if not kilometers here. Also, this is not visible in Quik.
