Digital orthophoto quarter quad or DOQQ is an aerial photo that is digitally corrected so that the scale is uniform and has the same lack of distortion as a map. These are like aerial photos with the distortion removed. DOQQ maps are spatially accurate with different planimetric features appearing in their true geographic positions on the planet.
