Description: Describes how to use an improved and greatly expanded version of an earlier computer program (1964) that converts dendrometer measurements of 3P-sample trees to population values in terms of whatever units user desires. Many new options are available, including that of obtaining a product-yield and appraisal report based on regression coefficients supplied by user. Improved techniques for extrapolation may be employed to estimate unseen length and upper bark thickness.

Keywords: 3P-sampling, optical dendrometry, timber realization value, timber appraisal, timber conversion to product-yield, sample-tree-measurement, extrapolation, tree volume, tree length, tree surface
