ORTHOIMAGERY, CONCORD WATERSHED, MIDDLESEX COUNTY, MASSACHUSETTS

Digital orthographic imagery datasets contain georeferenced images of the Earth's surface, collected by a sensor in which object displacement has been removed for sensor distortions and orientation, and terrain relief. Digital orthoimages have the geometric characteristics of a map, and image qualities of a photograph. (Source: Circular A-16, p. 16)
