Notes about the GTAG file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The GTAG file type is primarily associated with 'Jelbert GeoTagger' by Jelbert Consulting. The file is created by the Jelbert GeoTagger device and contains geographical information relating to where photographs are taken. The file consists of multiple lines of text with a version keyword at the beginning of each line. Currently GEOTAG2 is present and the data is then comma separated. Future versions of the Jelbert GeoTagger device will have different keywords and possibly different data separators. See product Web site for updates on the file format. You can process the stored information using RoboGEO.
