RAYSAW Computer Program Can Grade Hardwood Logs and Calculate its Value
Determining the most efficient and highest profit use of a hardwood can be a difficult endeavor. RAYSAW is a computer program developed by Forest Service scientists that allows researchers to examine various processing strategies for hardwood logs given log shape, size, and grade. In addition, RAYSAW can grade hardwood logs and estimate grade recovery using the Forest Service Hardwood Log Grades and Lumber Grade Yield tables. Coupled with current lumber price data, RAYSAW can estimate volume and value recovery estimates directly. The laser scan surface allows log volumes and sawing residue to be precisely determined. Thus, a complete valuation of a log, including lumber, cant, bark, sawdust, and residue can be calculated.
