| Our Feature Map Stereo Pair Perspective (Wausau, WI) Stereo image viewing allows us to see landforms in a 3D perspective. These grayscale stereo pair images were processed from a Digital Elevation Model (DEM) for an area just southwest Wausau, Wisconsin. This view looks northwesterly across Mosinee Hill (foreground) and Rib Mountain (background). The chief difficulty in making use of stereoscopic images is finding an easy method to view them. The crossed eyes method is perhaps best since it does not require any equipment, but only about one out of three people can view it this way. However with practice, many others can learn. Analglyph images are another way to provide stereoscopic 3D effects, but they require 2-color viewing glasses. These types of images are generally created by superimposing two color offsets to produce the depth effect. |
