BDATRINDE2HX {rBDAT}

Calculate double bark thickness

Description

BDAT-Function to get double bark thickness at given height Hx

Usage

BDATRINDE2HX(BDATArtNr, D1, H1 = 1.3, D2 = 0, H2 = 0, H, Hx)

Arguments

BDATArtNr

numeric vector of species code; see getSpeciesCode.

D1

first measured diameter of tree [cm] e.g. diameter in breast height

H1

measurement height of D1 [m]

D2

second measured diameter of tree, see buildTree for details on how to specify different taper forms

H2

measurement height of D2, see buildTree for details on how to specify different taper forms

H

total tree height [m]

Hx

height for which double bark thickness is required [m]

Details

This function returns double bark thickness in given height Hx in stem taper (hence, it depends on the diameter in given height). This can be added onto a diameter under bark to receive diameter over bark.

Value

vector of double bark thickness given height Hx inside stem taper.
