Using iPhoto's Places without a GPS-enabled camera

by Rob Griffiths, Macworld.com

iPhoto ’09’s Places feature lets you organize and view photos by location. If you’ve got a newer higher-end digital camera, it may make this process painless—if the camera has a GPS chip, then iPhoto will read the GPS data when you import your pictures. But if you don’t have a GPS-enabled camera, the process of assigning a place for every photo can be really time consuming.
