| Description: | Research note Abstract: The computer generation of shaded relief images for cartographic applications is analyzed. The geometric theory of image formation is presented in some detail, and is used to motivate the discussion of the image simulation algorithms developed at the U.S. Anny Engineer Topographic Laboratories (ETL). Several algorithms devised to address specific cartographic problems, such as variable sun angle, haze simulation, and relief contour algorithms, are also discussed. The successful implementation of these algorithms is described. Appendixes summarizing details of the theory are included, as are a Software User's Guide, sample images, and listings of the ETL software. |
