    Description

    A software package for drawing images of forested landscapes was developed. Programs included in the system convert topographic and stand polygon information output from a GIS into a form that can be read by a general-purpose ray-tracing renderer. Other programs generate definitions for surface features, mainly trees but ground surface textural properties as well. The package can be used to design logging cut unit boundaries that are less visible from a given viewpoint. Images created using the system may also be suitable for showing the public how a given prescription might appear if implemented. The package was used to make images showing the potential for using strip clearcutting as a means of mitigating the visual impact of harvests on steeply sloping ground. An analysis of the package indicated that there was a potential to improve its data handling and user interface components.
