1:12,000; Ground sample distance is 1 meter. photography

1996-97 color infrared (CIR) NAPP photography is the primary image source (refer to header file for actual photo source date). Digital orthophoto quarter-quads meet horizontal National Map Accuracy Standards (NMAS) at 1:12,000 scale (plus or minus 33 feet error). The geographic extent of the DOQ is equivalent to a quarter-quad. Each image also has between 50 and 300 meters of overedge to facilitate tonal matching for mosaicking of adjacent images.

Standard digital orthophotos, 3.75-minute coverage, are cast on the Universal Transverse Mercator (UTM) projection on the North American Datum of 1983 (NAD83) with coordinates in meters.
