DOQQ is abbreviated for digital orthophoto quarter. This georectified map (tied to coordinates and map projections) is a raster formatted photo image by high-altitude aerial photography. he DOQQ technique uses various types of films so that the image may be manipulated to be false color-infrared or in real color. The reason that false color is used is because it helps differentiate terrain features at the surface. The image above is a DOQQ image in Texas from 1995.
