Availability: Find a library where document is available Abstract: The old adage that one picture is worth a thousand words is really a conservative estimate when applied to elevational data points. Digital elevation data presently being gathered or converted from previous mapping efforts afford valuable data for transportation planners, but these data are not readily usable. When these data are converted to an aerial photolike scene, they offer a valuable additional planning tool. Surface simulation models based on U.S. Geological Survey (USGS) digital elevation models were accomplished on a VAX 11/780 with a Vectrix VX384 display. A Hermite curve technique was used to simulate the surface configuration of the terrain. The terrain surface simulation was overlaid with USGS digital line graph data to show transportation routes. In addition to vertical views, oblique views from any direction may be shown and the direction and vertical angle of the source of lighting may be chosen.
