Invalid GPS coordinates in GPX export from GoPro 6


I am trying to export a GPX track from an MP4 video filmed on GoPro 6.


Somehow I'm getting invalid coordinates. I see several problems which appear on the exported GPX track - but which I don't see on the GPS gauge in Quik.

First problem is that I'm getting completely off-the track coordinates. Here's a example:




The video is filmed in Germany (around 8.663, 50.232). A few first points on the exported GPX track lie north of Canada (-128.4998971, 80.8641778). Also the elevation for these points is exported as 20841.167 (in reality should be around 202).


Quik seem to show this track correctly:




The complete video is ca. 3.4GB so I can't reasonably share it. I also don't know how can I cut it while keeping all the streams including GoPro MET.


The .bin file I've exported from the video:


This is how I've exported it:


ffmpeg -y -i GX030039.MP4 -codec copy -map 0:3:handler_name:" GoPro MET" -f rawvideo  GX030039.bin


The exported GPX track:


Exported using:

gopro2gpx -i GX030039.bin -o GX030039.gpx


I've tried gopro2gpx from:

With the same result.


Invalid points look like:

			<trkpt lat="80.8641778" lon="-128.4998971">
			<trkpt lat="80.8641778" lon="-128.4998971">

First valid point:

			<trkpt lat="50.2319754" lon="8.6630605">


Did anyone experienced similar problems?


Are there any official tools for GPS data export from GoPro?

Re: Invalid GPS coordinates in GPX export from GoPro 6

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


BIN file:


This is the GPX track I'm getting:


The tracks looks "exploded" in a few places:




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




Same here:




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.


I also get severely inprecise coordinates along the track:




Quik shows a somewhat better looking track:




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.

Hi. Maybe you would like to try the export on This video shows how it works:

It does not show how to export: there are icon in the top left, one of them allows to export to GPX and CSV.


Please contact me on email if you would like to use it - I will grant you n access. Presently the access is limited to invited guests.




Watch your locally stored GoPro movies together with maps trails and altitude, speed, GPS signal quality charts: - go to - login with Facebook or Twitter account - in Studio menu select Video, or - goto Optimized for desktop Chrome browser. Login with ...

Install and use Dashware. It's free and Dashware and GoPro are cooperating with each other. When you import the file into Dashware, it makes a csv file. Open it with Excel to see everything.


As an alternative or additional, get RaceRender. You can only export 3 minutes with the free version, but you see the entire route. Pay some money and you can export to gpx. See this thread on the RaceRender forum for a lot of explanation and my on-going problems.


I use GPSU to edit/modify data before inputting into a mapping program.


GoPro is notoriously inaccurate in getting gps info. Before starting, take a short video clip to make sure that the GPS is on and had located a satellite.

Thank you for the suggestions.


Both RaceRender and Dashware give me more or less the same invalid points I get from gopro2gpx.


I just wonder why the track looks fine in Quik.

@epicwave02347 Check out the new version of GPMD2CSV:

GPX and KML exports now filter out inaccurate data. Hope it works well for your needs, it looks much better. Altitude is still pretty wild but that's normal on GPSs.
