[aerial photography]
Often abbreviated to DOQ. A 1-meter resolution digital orthorectified image basemap, comprising an area measuring 7.5-minutes longitude by 7.5-minutes latitude, covering the United States at a scale of 1:24,000, created from 1:40,000-scale black-and-white aerial photography. Produced for, and distributed by, the United States Geological Survey (USGS). Digital orthophoto quadrangles are true photographic maps in which the effects of tilt and relief are removed by transformation or rectification. The uniform scale of a DOQ allows accurate measurement of distances.
