SUMMARY

GPS position for RAW file or jpg-out-of-cam is different from processed jpg from RAW file.
Detail: I shoot with Olympus OM-D EM-5 in raw format (and jpg), process the raw file in DxO with output to jpg. If I select raw and processed jpg DigiKam geo localisation windows displays differen coordinates hence different postion on map.

If I display both files (raw and processed jpg) in Windows Photo app or with app GPSprune, the GPS coordinates and displayed position values are identically. I compared the read out of GPS values with exiftool.exe: identic values for all files.
As other programs display the correct position, I assume the problem is within DigiKam. If you need example files please let me know how to submit as I can not attach to this ticket (file size exceeds limit)

Coordinate readings from Digikam:
from raw orf: geo:52.4689466667,12.8763633336,0
from jpg ooc: geo:52.4689466667,12.8763633336,0
from jpg dxo: geo:52.4666666667,12.8666666667   <=== wrong values

Coordinate readings from exiftools (same with other programs)
for all files:
GPSLatitude                     : 52.4689466666667
GPSLongitude                    : 12.8763633333333

For Nikon files processed with DxO there is no problem. Don't know of other cameras.

STEPS TO REPRODUCE
1. check attached example files
2. select from digikam and open geo localisation window
3. you find .orf at correct position but .jpg at different position.

OBSERVED RESULT
differend GPS position in value column and different position on map.

EXPECTED RESULT
should be same values/position for all files
