Digital Orthophoto Quater Quads (DOQQ) are digital images that contain orthorectified aerial photography at a resolution of 1 meter. A DOQQ is a uniform scale photography image that makes it possible to determine map measurements. Features are represented in their true ground position making direct measurements possible. This map of Minneapolis, MN is a DOQQ that is a computer generated aerial photograph. It shows a large area of the city with great resolution.
