This is a clipped portion of the NW quadrant of Union Springs, NY. A digital orthophoto quadrangle (DOQ) 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. http://www.usgsquads.com/images/doqq_cir_unionsprg_small.jpg
