MOV file from DJI, GPS error

[fmp2a]

Hi,
Exiftool is a great tool. I use it from a very long time and I am happy with it.
But now I encounter a problem with new MOV files from DJI Phantom 3. Exiftool doesn't read correctly some tags.
I see errors or problems on GPS tags...

Here an output exemple:

Thanks for this report.

If you email me a sample mov file I'll take a look.  My email is philharvey66 at gmail.com

Thanks Phil.
I send you a private message with a link to download a test file.

I got the file, thanks.  I will patch ExifTool to properly decode these GPSCoordinates, but it would be nice to know what the other fields mean,  If you know the meanings of any of the other UserData tags (xsp,ysp,zsp,fpt,fyw,frl,gpt,gyw,grl), please let me know.  There are also some non-conforming UserData tags that aren't extracted (dji,res,uid,mdl -- mdl has a value of "FC300S", which looks like a camera model name to me).  I'll add support for extracting these too (all except mdl unknown for now).
