And neither of those solve the issue of photos i have that aren't tagged.
I use the following method to geotag the scans of my old slides:
- Find the exact loction in Google Earth or Google Maps; there are usually several geocoded photos shown in Google Earth, even out in the wild, so have I reference photos for free. Then mark the spot with a places pin on the map and copy the GPS coordinates from the Info panel.
- In Aperture I open "Manage My Places" and create a Place from the GPS coordinates and assign it to the photo.
- If you have Graphic Converter, you can use a shortcut: GraphicConverter has a command to geotag the currently edited photo with the GPS position that is currently viewed in Google Earth.
In Google Earth:
And in "Manage My Places" in Aperture:
Enter the coordinates - first the latitude, a comma, the longitude to create a new place.
