| Abstract | Digital Ortho Quarter Quad (DOQQ) 1992 Grayscale Imagery - Pima County. A Digital Orthophoto Quarter Quadrangle (DOQQ) is a computer-generated image of an aerial photograph in which image displacement caused by terrain relief and camera tilts has been removed. It combines the image characteristics of a photograph with the geometric qualities of a map. Standard DOQQ's produced by the U.S. Geological Survey (USGS) are either grayscale or color-infrared (CIR) images with a 1-meter ground resolution; they cover an area measuring 3.75- minutes longitude by 3.75-minutes latitude, or approximately 5 miles on each side.
