The Digital Orthophoto Quarter Quadrangle is a pixel based aerial photo that cover large areas of land and are beneficial for planning or surveying purposes. It is a photo, but its pixelation gives it map-like qualities. The map above has corrected distortion for the area of Necedah, WI in order to get a pixilated image that corresponds to the Earth's surface.
