This animation is a virtual fly-through near the Clatsop Spit, Oregon, just south of the Columbia River. It was created using the 3-D surface tools provided in Research Systems, Inc. ENVIŽ software by draping an image color-coded by elevation over a digital elevation model derived from the spring 1998 LIDAR survey. The fly-through begins at the north end of the beach and moves south across the dune field at a fixed elevation. The camera is looking straight ahead throughout the fly-through. The static image above the animation provides a perspective view of the beach with the red line representing the flight path of the fly-through. The highest elevation for the region shown is no more than 45 feet. The region of highest elevation is seen near the midpoint of the fly-through.
