I have successfully used the command line exiftool to write GPS lat and long to my photos exif data but when I use the decimal degree format I can only get 6 decimal places written for GPSLatitude and GPSLongitude. We have cm level accuracy on all of our camera nodal points (we are surveyors) and truncating to 6 decimal places is degrading our position. Latitude expressed to 6 decimal places where I live is around 0.1 meters. I need at least 7 and preferably 8 decimal places.
Is there a way to increase the precision when writing GPSLatitude and GPSLongitude to my photos exif data?
Use the -n option to extract the full decimal number written to the file. Also look at the -c option for more control over the output.
Thanks StarGeek! When I view the photo exif data using -n all the precision I need is indeed there. My photogrammetry software is also rounding to 6 decimal places and I thought that exiftool was not writing all the information from my survey control. But it is!
Thanks again! Fantastic tool...
