The Virtual Forest: Advanced Three-Dimensional Visualization Techniques for Forest Research and Management
David J. BuckleyCraig Ulbricht
The use of three-dimensional based visualization techniques in GIS has historically been applied for consideration of visual impact assessments. In particular, the aesthetics of forestry harvest cut block shape, size, and location have been of primary importance. However, to date GIS technology has not provided visualization functionality that affords realistic representation of the forested landscape. This paper reviews the issues involved, and the capabilities achieved, by integrating scientific visualization techniques with ArcInfo. In particular, this paper will focus on the integration of surface rendering functions and map animation tools using ArcInfo databases. These techniques are of interest to foresters in evaluating aesthetic issues related to harvest cut block design and operating plan approval. Conventional visual exposure analysis and three-dimensional surface fly-bys with advanced tree object rendering are the primary capabilities utilized. The striking realism of the visualizations generated in this project have enhanced foresters' ability to communicate their planned management activities. Multiple examples will be presented.
