Ruby app to copy GPS data from an Aperture library to Lightroom.
This assumes you have migrated your Aperture library to Lightroom using the "Import from from Aperture library" plugin in Lightroom. For more info see: https://helpx.adobe.com/uk/lightroom-classic/help/migrate-photos-aperture.html
After doing this I found that all my photos and metadata had been copied over except for GPS data that had been manually assigned in Aperture.
Currently the app only support copying GPS data over in an individual project basis.
./bin/aperture_gps_2_lightroom <project_name>
Example:
./bin/aperture_gps_2_lightroom "Amathus Ruins"
Found 55 versions with GPS in Amathus Ruins

Both Aperture and Lightroom use SQLite for the databases.
Process overview:
- Get Aperture versions in given project that have a GPS location
- Load/Generate static file with SHA1 hashes of all lightroom images
- Iterate over Aperture versions
- Find lightroom images with matching file hash
- Update lightroom image GPS
Aperture database location: Aperture Library.aplibrary/Database/apdb/Library.apdb
Sample queries:
-- Show GPS for specific version
SELECT exifLatitude, exifLongitude
FROM RKVersion
WHERE uuid = '5Cclfkh7QpaQP6glm+Bp3w';
-- Show GPS for all versions in a given project
SELECT masterUuid, fileName, versionNumber, exifLatitude, exifLongitude
FROM RKVersion
WHERE projectUuid = '7kFRTjp%TGGDRD8GOKl5og'
AND showInLibrary = 1
AND exifLatitude IS NOT NULL
AND exifLongitude IS NOT NULL;
-- List projects
SELECT uuid, Name FROM RKFolder WHERE folderType = 2;Lightroom database location: Lightroom/Lightroom.lrcat
