DOQQ - Digital Orthophoto Quarter Quads

http://www.nd.edu/~underc/east/maps/

DOQQs combine an areal photograph with the geometric qualities of a map by georeferencing the image and orthorectifying it. Orthorectification is the process of adjusting the photographs to minimize distortion created in capturing an image of three dimensional terrain and translating the information to a two dimensional map.
