Tree Crown Shape and Morphometric Parameters R package crownmetrics version 0.1.0 Provides functions to compute tree crown volume and projected area using geometric solid approximations (ellipsoid, cone, cylinder, paraboloid, and fan shapes), and to calculate morphometric indices commonly used in forest inventory and silviculture, including crown ratio, crown form factor, slenderness, salience index, and scope index. Methods are based on peer-reviewed literature in forest science.
