[null,null,null,"Sommario/riassunto","The ability to measure roundwood quantity and quality, and predict product yields is of great importance to forest industries. However, roundwood metrics is a topic that is often difficult to understand due to counterintuitive trends, inconsistencies and variability in a number of factors. This book provides a comprehensive guide to the various methods by which roundwood and the products of roundwood are measured. It presents and compares many different log scaling methods in terms of procedures and conversion ratios."]
