Software

The software for Sylvan Stand Structure Model has gone through many iterations and some software has been removed as it becomes out of date. The current iteration of the model has four main modules and several service modules.

Software Modules

Input

(In development) Input is designed to read your data entered into a spreadsheet and then passed to this program. It generates a set of parameters for the plot. This program will be graphically oriented to allow your to interact with the input data and produce parameters that make sense. Then the program will output a properly formated and parameterized file in the Sylvan format.

Generate

Generate is a program that reads the file produced by Input and generates a stand of a similar statistical character at a nominal unit area (1 acre for english units and 1 hectare for metric units). Users seldom measure mapped plots at these large dimensions. The model works much better with a larger plot to grow. This module is none graphical and requires a Sylvan file in and producing a Sylvan file out.

Grow

Grow is a program the takes a plot and steps the plot forward a number of time steps. This module is none graphical and requires a Sylvan file in and producing a Sylvan file out.

View

Sylview is a program that takes a Sylvan output file and lets you view the model output in graphical, map, profile and tabular views.
