With Apple Photos 2.0 and HoudahGeo 5.1 running on Sierra it again possible to notify Photos of changes made to location information. The location information will thus always stay with the images. Just the same as if you had used a GPS camera. The above workflow also ensures that GPS information is stored as EXIF/XMP tags within the image files. Adding the GPS information before import is faster. The process of updating the iPhoto or Aperture library for thousands of photos can be rather slow. Import the tagged files into your Photos library.Write EXIF/XMP geotags to the image files.Geocode the photos using third party software like HoudahGeo or other free software.Import photos using the Image Capture application.Until Apple adds the option to change location information via Apple Script, we have to resort to a less elegant workflow. This is not currently possible with the new Photos application. The last step of the workflow uses Apple Script to update the library to reflect the location information added to the files. Have HoudahGeo notify iPhoto or Aperture of the newly added geotags.Write geotags to the original image files.Geocode the photos using HoudahGeo or other free software.When used with iPhoto or Aperture, this allows for a very elegant workflow: I develop the photo geocoding software HoudahGeo. Unfortunately location information is also read-only by the way of Apple Script. The 'Photos Help' puts it this way: 'If your camera has GPS capability (as iPhone does), or you’ve added GPS information to your photos, Photos can automatically display your photos on a map.' It can also show photos belonging to a collection or moment on a map. Photos reads GPS coordinates from image files during import and displays the location in the Info window. In OS X 10.10's Photos application, location information is read-only.
