A DOQ is a digital raster (pixel-based) image of an aerial photograph in which displacements caused by the camera and the terrain have been removed. It combines the image characteristics of a photograph with the geometric qualities of a map. The digital image is rectified by processing each image pixel (picture element) through equations using ground control points that can be identified from photographs, camera calibration, and orientation parameters, and a digital elevation model (DEM).
