Imagine a large image. UV means to move the CAMERA from a particular set of coordinates to another. It doesn't move the image itself like XY, just the view. Umm...get it? *notices your NNID* OK, Celadon City is just a large map right? But our view is always one screen at a time. That's because the camera moves with UV. It doesn't actually move the entire Celadon map around, just the view.
