rBDAT (version 1.0.0)

Implementation of BDAT Tree Taper Fortran Functions

Description

Implementing the BDAT tree taper Fortran routines, which were developed for the German National Forest Inventory (NFI), to calculate diameters, volume, assortments, double bark thickness and biomass for different tree species based on tree characteristics and sorting information. See Kublin (2003) for details.
