If you have aerial photographs, satellite images, or scanned maps, and want to use them as background maps, PhotoFit is what you need. It loads an image file and allows the user to pick visible points in the image that have known coordinates. The image is then rectified (de-skewed or rubber-sheeted), and a transformation created to allow the image to be displayed in the coordinate system of choice.
