Any map image (scanned/photographed with a high-res digital camera/downloaded from the Internet) in GIF, BMP or PNG format with a pair of known lat/long calibration points on it can be displayed inside UIview. You can cause a cross-hairs to be displayed at your own position from a local GPS.

This shareware utility can download any number of map images to cover a specified lat/long-bounded box, and then stitch them together to form a far larger single image, ready to use in UIivew.  You can create images far larger than the small window you see     online on Google and Yahoo maps.  I have created large-area hi-res maps that involved over a thousand tiles!

UIview then becomes a scrollable viewport showing part of a far larger image.       I have used maps of over 2500 x 3500 pixels in UIview.  The key is to reduce the number of colors in the image to only 256 or even 16 colors.
