DIB_ICalculator: Calculate the inside-bark diameter at a given height

DIB_ICalculatorR Documentation

Calculate the inside-bark diameter at a given height

Description

This function uses taper equation to calculate diameter inside bark at a given height. It is equivalent to the subroutine of vol_tree_active_equation in vol_setup macro

Usage

DIB_ICalculator(
  taperEquationForm,
  FIZorBEC,
  species,
  height_I,
  heightTotal,
  DBH,
  volMultiplier
)

## S4 method for signature 
## 'character,character,character,numeric,numeric,numeric,numeric'
DIB_ICalculator(
  taperEquationForm,
  FIZorBEC,
  species,
  height_I,
  heightTotal,
  DBH,
  volMultiplier
)

Arguments

taperEquationForm

character, Specifies which taper equations will be used, currently support KBEC or KFIZ3. KBEC is the Kozak's equations (2002 version) based on BEC zone, tree sizes and species. KFIZ3 is the equations based on forest inventory zone (FIZ), tree sizes and species. Default is KBEC, if missing.

FIZorBEC

character, Specifies which FIZ or BEC (depends on taperEquationForm) zones the tree located in BC.

species

character, Species code.

height_I

numeric, Height from ground.

heightTotal

numeric, Total height of a tree.

DBH

numeric, Diameter at breast height.

volMultiplier

numeric, Volume adjustment multiplier.

Value

Diameter inside bark
