The GPS data in the photos I've saved to my phone from the drone places them way out in the Mediterranean Sea north of Egypt. That's a long way away from St. Paul Minnesota...

I did notice that my flight records contain correct info - it just seems like they're exporting the location to the EXIF data wrong, like it's missing a negative sign or something?

May I have the original picture from the SD card and the location that you actually flew in? I would like to check, you can upload the photo to Dropbox so I can grab it. Thank you.

I think that also the altitude is recorded incorrectly. The EXIF reference says that the altitude is "Above sea level" but it seems that it Air records relative altitude from start point.

I think that's the default location point for when you actually lack a gps signal.
Fwiw I just checked a Mavic Air DNG someone uploaded in another thread and its GPS data was correct -- are your images DNG or JPG?

IIRC there have been differences in the way coordinates were written into EXIF data on DNG and JPG in past Mavic firmware.

Just to follow up - it appears that the last firmware update fixed this issue. It was writing the same coordinates in the Middle East for everything on export, but now the EXIF data is correct.

Unfortunately, the firmware did not fix the problem with Altitude.

In my case Absolute Altitude parameter is always 1.20m, and Relative Altitude is the height above ground when photo was taken, although EXIF reference states it is "Above Sea Level".

This happened to me today.

Normal short picture shoot flight. Takeoff in Sport mode with thumbsticks start.


Positioned for shot, took two photos. Both photos have:
EXIF GPS coords:
Latitude: 31° 31’ 31,002” N,
Longitude: 31° 31’ 31,002” E,
Altitude: 31 m (101,71 ft),
Altitude reference: above sea level,
GPS-version: 2.3.0.0

Running Mavic Air with DJI GO 4 (4.2.22)

I am seeing the same issue from recent flights. The altitude in the EXIF is using the AGL value, not GPS. I was flying at 75m but the location was over 200m above sea level.

Mine still does this. What firmware version are you on? I’m sure I’m on the right version.
