These two images were created by draping an aerial photograph of South Beach, Oregon, over a digital elevation model derived from LIDAR data collected during the spring 1998 survey. The images differ in that the viewing angle and elevation change from one image to the next. The viewing perspective for the top image is closer to the ground and more southerly than the second image. This technique gives dimension to a typically flat, two-dimensional photograph. The dune ridge along with its relative elevation is easily discernible on the right side of the image. The rise of the jetty extending into the water may be observed at the northern end of the image. The patches of white within the water indicate areas of no data.
The two images below were created by draping a surface color-coded by
elevation over a digital elevation model derived from LIDAR data. The
area and perspective shown are the same as those of the aerial
photograph and the digital elevation model. Again, this technique
gives height to a typically flat two-dimensional color-coded image. Research Systems, Inc. ENVIŽ software tools
were used to create the images on this page.
