GPS Lat/Long EXIF write precision.

[david69cn]

Exiftool is very easy to use and runs very fast, thanks to Phil Harvey
I have used exiftool to successfully write GPS latitude, longitude and altitude information to my photos. but the number of digits after the decimal point is only 6 digits. The precision of latitude and longitude is not enough. I need to keep 8 digits after the decimal point. How to deal with it?

thank you!

The stored value keeps more than 8 digits of precision.  Use the -n option or add a "#" to the tag name to see the full precision, the -c option to use the format of your choice, or the -v option to see how it is actually stored (as 3 rational values):
