Can you add extra meta data to images in the same way you can with music files?
Like, could you make an app that reads the GPS coordinates from the EXIF data, looks up the human readable name of the place of those coordinates, and adds that info to the meta data, so that any application that wants could read this position data and let you search for images taken in for example Oslo, Norway, or even in the Grünerløkka part of Oslo?
@forteller
Yes, in general you can, although it depends on which image format you are using. And the choice of software depends on what operating system you are using.
@forteller I wrote a (cross-platform) program for reading EXIF data once. It shouldn't be a major undertaking to do what you ask if there's a service which translates coordinates to place names.
@forteller looks like the XMP metadata supports city at least:
@forteller maybe https://geosetter.de/en/main-en/? But searching or grouping on a map is better solved with a GIS approach than tagging with everything relevant to the coordinates.
@kefir That looks to me like it just adds a map, not the searchable place names? Anyway I'm on Linux, not Windows. But appreciate the thought! :)
@forteller It can add location names to the image metadata as well.
"Automatic filling of location IPTC fields and altitude values (requires internet connection)"
I've never used it, but it was mentioned when following this discussion:
https://exiftool.org/forum/index.php?topic=10822.msg57665#msg57665
This might also be useful if you want to use exiftool directly by getting the GPS coords, looking up a name and then writing that to the image metadata again, which is what I think you wanted to do.
