GLI Ray Tracer

Owners: Lora Murphy and Charles Canham.

This program takes as input a set of trees and a set of light rays and determines, for each ray, which trees intersect it. A help file can be found here. This tool is available as Java source code. You are responsible for compiling and running the code.

GLI Ray Tracer, UQAM Version

Owners: Frédéric Boivin and Anil Ediriweera.

This is a modification of the GLI Ray Tracer program, with different allometry functions:

Height = b0 + b1(DBH)
and
Height of canopy bottom = Height - (C2 x (Height)β )

Harvest with Advanced Regeneration Protection (HARP)

Owner: Mark Vanderwel

This program implements a harvest prescription termed HARP (Harvest with Advanced Regeneration Protection). It is a combination of stripcutting (all trees are cut along parallel vertical skid trails) and diameter-limit cutting (all trees above a lower diameter threshold are cut). It is designed to be implemented through the Harvest Interface feature of SORTIE, and can be combined with the Lagged Post Harvest Growth and Post Harvest Skidding Mortality behaviors. This is as published in Thorpe et al 2010.

Spatial Partial Harvest

Owner: Mark Vanderwel

This program implements a partial harvest prescription that is specified in terms of intensity and spatial pattern. It is designed to be implemented through the Harvest Interface feature of SORTIE. This is as published in Vanderwel et al 2011.
