Often when making a scan it is hard to get the image precisely aligned; sometimes with old maps the paper has stretched. It can be useful where you want to make a tiled map from a number of original images. The program can also be useful when dealing with maps of an unknown projection because the map can be stretched to fit another coordinate system.";
