Stand Visualization System

The Stand Visualization System (SVS) generates graphic images depicting stand conditions represented by a list of individual stand components, e.g., trees, shrubs, and down material using detailed geometric models of individual trees and other stand components. The images produced by SVS, while abstract, provide a readily understood representation of stand conditions and help communicate silvicultural treatments and forest management alternatives to a variety of audiences. SVS provides the following capabilities:

- display overhead, profile and perspective views of a stand;
- differentiate between stand components using different plant forms, colors, or other types of marking as specified by users;
- provide a mechanism that allows users to define plant growth form, stem color, and foliage colors based on species, growth form, and plant position within the canopy;
- provide tabular and graphical summaries of information represented in a stand image;
- facilitate the design of silvicultural treatments by allowing users to select individual stand components and specify treatments; and
- display information describing individual stand components as they are selected by the user.

A data conversion program, FVS2SVS, links SVS to the Forest Vegetation Simulator (FVS) to provide stand growth modeling and visualization capabilities for most geographic regions in the U.S.
The SVS software is currently used by a wide variety of users in federal agencies within the U.S., private industry, academia, and research organizations.
