The Lightroom Aperture import plug-in doesn't import GPS data when added manually in Aperture. It happens also randomly for exposure time modified manually in Aperture
Thanks in advance

I confirm that I have the same problem. Lightroom Aperture import plug-in does import GPS data from Aperture when originally inserted by the camera, but never when manually added in Aperture.
This problem seems to be known (several discussions on this topic), but I have not seen any (practical) correction proposed.
I have several 10 k of photos with Aperture manually added GPS data, and I do not wand to redo the work which has taken me months ...

Any idea is welcome.

I assume Aperture behaves like LR; it does not store added GPS data in the actual image files, only in the catalog or sidecar files. I have to use ExifTool to copy the manually added GPS data from the xmp sidecar files in LR to the actual nef files, so that they are there for good, whatever program I may use in the future.

A minor clarification for other readers: LR does write back GPS info (and all other metadata) to TIFF and JPEG files, but not to raw files -- it writes to the .xmp sidecar files, as Bob explained.

I understand that all data that I have added under Aperture are stored in the Aperture library, not on the files themselves.

For clarification : I use Aperture with referenced files (not managed files).

But the main purpose of the Lightroom Aperture import plug-in is to import data from the library, not from the files (otherwise, I would have imported the referenced photos directly into LR without bothering with data introduced in Aperture).
Other data added "manually" in Aperture are well imported using the plug-in, but the GPS data are not.

I am still stuck with this problem.

Skimming this thread https://discussions.apple.com/thread/... suggests a couple of possible solutions:

- Use the HoudaGeo program to get the GPS location from the Aperture library into the metadata fields in the masters (or their sidecars). Then you can import the masters directly into LR, and it will pick up the GPS.

- The thread suggests using Aperture's File > Export > Metadata to export a text file containing filenames and GPS locations. You could then use the LR/Transporter plugin to import that metadata into the LR catalog.

I don't know Aperture, so I can't say with any confidence that either of these will work.

Re HoudaGeo, see this article: http://photoapps.expert/tips/2014/7/2...

I have already tried to explore the first solution (HoudaGeo).
This solution has the big drawback to modify all my (approx. 130 000) master photos, by a software which I still do not fully understand and trust.
Can I trust HoudaGeo, and be sure that no other change will be brought to my master photos ? I have checked that sidecars work only with RAW format, and not JPEG (which I am using).

Regarding your second proposed solution, could you kindly tell me a little more on the LR/Transporter plugin ?
Many thanks in advance.

The LR/Transporter plugin is a popular plugin that lets you import and export photo metadata in bulk: http://www.photographers-toolbox.com/...

It's often mentioned in the LR forums and the author has a good reputation.
