An awful lot of geotagging utilities for the Mac (adding metadata to a file is probably not a difficult programming task). Here are two more, from the same company: PhotoInfoEditor and PhotoGPSEditor; they’re practically identical except that the latter adds GPX/NMEA file support. Each has a built-in Google Maps interface that could stand some improvement: I found it very non-intuitive. Via TUAW.
