DOQs produced by the U.S. Geological Survey (USGS) are either gray-scale, natural color, or color-infrared (CIR) images with 1-meter ground resolution. They cover an area measuring 3.75­minutes longitude by 3.75-minutes latitude or 7.5-minutes longitude by 7.5­minutes latitude. Each DOQ has between 50 and 300 meters of overedge image beyond the latitude and longitude corner crosses embedded in the image. This overedge facilitates tonal matching and mosaicking adjacent images.
