Moving Default Scenery

How do you move the default scenery in FS9?
I made some photo scenery, and now I notice that skyscrpers, bridges, landmarks, airport terminals (I've already got moving runways down), etc. are misplaced sometimes by almost 1/3 of a mile.
What is the best way to move them?
Thanks!
