There is confusing display of pose metadata for photos in photo tab which have negative altitude reference. Need better representation or a checkmark that it shows that this WGS84 pose uses sea level or not otherwise it shows negative coordinates in metadata but pose actually is correct.

GPSAltitudeRef Indicates the altitude used as the reference altitude. If the reference is sea level and the altitude is above sea level, 0 is given. If the altitude is below sea level, a value of 1 is given and the altitude is indicated as an absolute value in the GPSAltitude tag. The reference unit is meters.
