A digital orthophoto quadrangle, DOQQ, is a computer-generated image of an aerial photograph in which image displacement caused by terrain relief and camera tilts is removed. It combines the image characteristics of a photograph with the geometric qualities of a map. They contain aerial photography at a resolution of 1 meter.
The above image is a DOQQ map showing regions located along Lake Travis and containing most of Lago Vista, Texas and parts of Lakeway,Texas and Jonestown, Texas.
