Alternatively you can set your camera time to GMT (http://wwp.greenwichmeantime.com/) which can be handy as you won’t have to set summer/winter time or when you travel through time zones.

2) Take pictures while recording a tracklog

Make sure your GPS receiver is recording a track log. Keep your GPSr ON during all the time you take pictures.

3) Download exiftool

Get the latest version from https://exiftool.org/ or install it from the installer of your Linux distribution. In Windows you need to copy the exiftool executable to some directory included in the %PATH% environment variable, for example c:\Windows.

4) Download ( ffmpeg / ffprobe ) (optional)

Ffmpeg is required to read the GPS latitude / longitude and GPSDatetime from the video GoPro files. Get the latest version from https://ffmpeg.org/ or install it from the installer of your Linux distribution. In Windows you need to copy the ffmpeg and ffprobe executable to some directory included in the %PATH% environment variable, for example c:\Windows.

5) Run from command-line SyncMediaTrack

First it is advisable to check that the images are well located,

SyncMediaTrack updatemedia --dry-run --geoservice --track XXXX.gpx photos/Andorra

Once we have verified that everything is correct we can execute it again adding the correct geographic positions

SyncMediaTrack updatemedia --track XXXX.gpx photos/Andorra

Reorganize your tracks

If you have several tracks you can reorganize them chronologically and geolocalized with the following command

SyncMediaTrack updatetrack --track <trackdir or gpx file> ---geoservice

Trouble Shooting

No indications of localization appears

Check your gpx file first then your pictures this way.

You can open and modify your GPX file easily in a text editor: it has plenty of tags

<tag>
....
</tag>

Gpx files have one or more

<trkseg>

which contain plenty of trackpoints

which says at which location you were at a precise time.
