Despite the importance of DEMs, cartographers and GIS specialists generally hesitate to manipulate DEMs for enhancing 3D visualizationsР’вЂ”in contrast to their willingness to modify vector data routinely to enhance 2D maps. The types of 3D visualizations created by the NPS include geologic block diagrams natural science illustrations, 3D hiking maps, Heinrich Berann-style panoramas, and birds-eye views of cultural sites showing buildings, landscaping, and vegetation set on topographic models.Р”ВEMsР’вЂ”the term is used generically here to describe all varieties of spatially-arranged elevation data, regardless of formatР’вЂ”comprise the digital foundation upon which all 3D landscape visualizations are based. Over the past five years, the NPS has relied increasingly on portraying geographic information through 3D visualizationsР’вЂ”static images, animations, and interactive scenesР’вЂ”which are assumed to be more easily understood by casual visitors than more abstract two-dimensional (2D) maps and illustrations in interpreting the natural and cultural resources of the 384 units in the National Park System. National Park Service (NPS) in manipulating Digital Elevation Models (DEMs) for the design and production of 3D landscape visualizations. This article discusses the graphical techniques used by the U.S.

In addition, Mac OSX users can export 16-bit DEMs from Photoshop 7.0 and CS in PGM format readable by Bryce using the free CartaPGM filter developed by Pascal Lamboley and Bernhard Jenny available here. 8), which now includes expanded support for 16-bit data, including layering, the DEM manipulation techniques described below are much easier to accomplish.
