Geolocation in Raw Imagefiles

[Joachim Ullrich]

Hello all,

I geolocalize all my photos. With raw files I configured digikam to write to
sidecar files (xmp). This works fine for comments, tags and selection
criteria. I expected to find the gps coordinates in the xmp file, but that is
not the case.

I used "image->write meta data to image file" to enforce an update of the meta
data in the xmp file. The timestamp of the xmp file changes, but gps positions
are not written to.

With jpg files, digikam writes the gps position to the image file as I have
checked with exiftool.

Anyhow digikam knows the gps position for the raw image and associates the gps
positions to the jpg files, which are generated from the raw files. But these
positions are not written to the image file. Even using the command from the
menu.

I assume the the positions are stored in the database. Is there a easy way to
read the position from the database by a script? Writing to the image file or
the xmp file using exiftool is done easily.

Thanks for help

Regards
Joachim

Hi,

Now I have not tested it for a while but there have been problems with coexisting metadata(e.g. tags) and geo coordinations in the xmp sidecar files.

If you test, with one pic, to write metadata to the xmp file and then geolocate I wouldn't be surprised if there will be only geo-data in that file. The same would also happen the other way around.
