Netvsl -- A Computer Program for Calculation of Tree Volumes with Interior Defect

摘要

This comprehensive computer program, written in FORTRAN IV language, calculates gross and net volume, surface area, and length from stem measurements. Tree input data include measurements of lengths, diameters, and cull dimensions obtained from felled trees; gross volumes of standing trees may be computed from Barr and Stroud optical dendrometer measurements. Various merchantability standards can be applied simultaneously to identical input data to obtain correspondingly various volume data output. This paper includes typical instructions for collecting and compiling tree data. (Author)
