Geocoding and digiKam
Locked
 
|
Hello,
Sometimes I use ExifTool to geotag photos. The geotagging command I use looks something like this: exiftool -overwrite_original -GPSLongitude=52.5487429714954 -GPSLatitude=-1.81602098644987 . Both Flickr and Gwenview handle and display geotags correctly. However, digiKam doesn't seem to recognize geotags, so the photos are displayed as if they have no geographical coordinates in their metadata. Any ideas what causes the problem and how to fix it? Thank you! Best, Dmitri _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Hi Dimitri, Few month ago an user report to bugzilla that digiKam must take a care about the precision of GPS info embedded in Exif. Typically, the GPS device need to be well synchronized with the satellite to have enough precision of position measurement. This prevent wrong map position of image when precision is not enough. This is debated in this file : https://bugs.kde.org/show_bug.cgi?id=326406 Look also if this file is relevant of your problem : https://bugs.kde.org/show_bug.cgi?id=353458 So there is another Exif GPS tags to add to said to digiKam to handle the information. Look in image metadata if you don't miss the references of lat and long info : Exif.GPSInfo.GPSLatitudeRefLook in code, it's not too complex to understand : If these 2 tags are not present, the GPS info is not decoded.

Thanks for your detailed reply, Gilles! I'll look into it.
