DOQQ Map

A DOQQ map or Digital Orthophoto Quarter-Quadrangles map uses a computer generated aerial photo and uses the geometric features of a map. They are created by using a camera that is sensitive to terrain displacement to create the image. I chose the map below because it demonstrates the sensitivity of the camera as it captures even the sand shelf that lies underwater directly off the beach.
