Hello barrubba,

Can you share any original image from your set? Quite a while ago we have observed similar issue with Below Sea Level tag in the EXIF for some of the datasets provided by users. And then it was related to the firmware issue.

I think that add_altitude script would help you, if you know approximate height above ellipsoid, on which the images where taken:

The script adds fixed Z offset to all cameras in the Reference pane.
