Detailed Description

Merchantable Timber Value Calculator Version 1.0.

This class calculates merchantable tree timber value according to a US Forest Service equation. The value is stored in an float tree data member that this behavior adds, as a value in an unspecified currency (user's choice). This also creates a grid object with species total values.

The value is price per thousand board feet of timber. The amount of timber in a tree is based on the size of the tree and the number of 16-foot logs that can be extracted from a tree.

The number of 16-foot logs a tree can provide is based on the bole length. The base of the bole is the top of the cut stump (whatever that is; it's ignored by this behavior); the top of the bole is the merchantable height. This behavior defines the merchantable height as the height at which the trunk diameter inside the bark tapers to 60% of DBH.

There's no simple equation to determine how many 16 foot logs fit into the length of the bole. This behavior uses a table along with trial-and-error to fit as many 16-foot logs as possible in before the 60% taper occurs. The amount of taper at the top of the first 16-foot log is established by the form classes and is a fixed percentage entered by the user as a parameter.

All trees above the minimum DBH are assumed to have at least 1 16-foot log. The amount of taper at the top of this first log is subtracted from the DBH, to see how much taper is left before the 60% merchantable-height taper is reached. The table below, adapted from Messavage and Girard, is contained in the code. It represents the amount of taper at the top of the last log in a tree containing different numbers of logs.

Consider a maple tree with a 20-inch DBH. The user enters its form class as 79%. We calculate the merchantable height to be that height at which the tree diameter inside the bark is 20 * 0.6 = 12 inches. The diameter at the top of the first 16-foot log = 20 * 0.79 = 15.8 inches.

The diameter at merchantable height is 12 inches; at the top of the first log it is 15.8 inches. This means there is 3.8 inches of taper available left. The next job is to use the lookup table to determine how many logs will fit into this amount of taper.

Our DBH is 20 inches, which has an entry for itself in the lookup table. If our DBH was not an even multiple of 2 inches, we would round down to the next lowest multiple of 2. Any tree larger than 40 inches of DBH will use the 40-inch entry. Trees must have a DBH of at least 10 inches to get a volume.

We begin by assuming that our tree is a 2-log tree. The amount of taper to the top of the second log in the table is given as 2.1. This means our diameter at the top of the second log is 15.8 - 2.1 = 13.7 inches. This is greater than 12 inches; so we will go back and try to fit three logs in.

For a 3-log tree of 20 inches, the taper at the top of the third log is 3.6 inches. The diameter at the top of this log is 15.8 - 3.6 = 12.2. This is still greater than 12, so we will try to fit in four logs.

The diameter at the top of the fourth log of a 4-log tree of 20 inches DBH is 15.8 - 1.4 - 1.8 - 2.4, or 10.2. This is less than 12. Thus, 4 logs don't fit. Our tree thus provides 3 16-foot logs.

Once we know the number of 16-foot logs, then we can use another set of tables to find out how many board-feet of timber those logs provide. The table used is based on form class (again, from Messavage and Girard). The timber is assumed to be 0.25" in width.

This behavior adds an float data member called "Merch Val" to trees that holds the value of the tree's timber.

This class's namestring and parameter call string are both "MerchValueCalculator".

This behavior may not be applied to seedlings.

Constructor & Destructor Documentation

◆ clMerchValueCalculator()

clMerchValueCalculator::clMerchValueCalculator ( clSimManager * p_oSimManager )

Constructor.

Parameters

p_oSimManager clSimManager object.

◆ ~clMerchValueCalculator()

clMerchValueCalculator::~clMerchValueCalculator ( )

Destructor.

Deletes arrays.

Member Function Documentation

◆ Action()

void clMerchValueCalculator::Action ( )

virtual

Makes value calculations.

First, the values in the "Merchantable Timber Value" grid are cleared. Then a query is sent to the tree population to get all trees to which this behavior is applied. For each, the value is calculated by GetTreeValue(). This value is placed in the "Merch Val" float tree data member. The species totals are put in the "Merchantable Timber Value" grid.

Reimplemented from clBehaviorBase.

◆ FormatQueryString()

void clMerchValueCalculator::FormatQueryString ( clTreePopulation * p_oPop )

protected

Formats the string in m_cQuery.

This value will be used in Action() to pass to clTreePopulation::Find() in order to get the trees to act on.

Parameters

p_oPop Tree population object.

◆ GetData()

void clMerchValueCalculator::GetData ( xercesc::DOMDocument * p_oDoc )

virtual

Does setup for this behavior.

Calls:

GetParameterFileData()
FormatQueryString()
PopulateTables()
SetupGrid()
Action() so that the initial conditions value will be added

Parameters

p_oDoc DOM tree of parsed input file.

Implements clWorkerBase.

◆ GetNumLogs()

int clMerchValueCalculator::GetNumLogs	(	const float &	fDBH,
		const int &	iSpecies
	)

protected

Gets the number of logs in the merchantable bole height of a tree.

This function calculates the number of logs in a tree. It calculates the taper to the top of the first log using the form class for the species. After determining how much taper is left, it uses the taper table to determine how many logs to add. It determines the DBH increment index by rounding down to the nearest even number and subtracting 10 (with a max index of 15). Then, for that index, it moves from 0 to m_iMaxLogs across the table until it finds the greatest entry that is less than or equal to the remaining taper. That array index is equal to the number of logs to add to the first one. The maximum value is 6.

This function does not weed out trees with a DBH of less than 10 inches.

Parameters

fDBH	SORTIE's DBH value, in in
iSpecies	Tree's species.

Returns: Number of 16-foot logs in a tree.

◆ GetParameterFileData()

void clMerchValueCalculator::GetParameterFileData	(	xercesc::DOMDocument *	p_oDoc,
		clTreePopulation *	p_oPop
	)

protected

Reads values from the parameter file.

Parameters

p_oDoc	DOM tree of parsed input file.
p_oPop	Tree population object.

Exceptions

modelErr if a form class value is not equal to 78, 79, 80, 81, 84, or 85.

◆ GetTreeValue()

float clMerchValueCalculator::GetTreeValue	(	const float &	fDBH,
		const int &	iSpecies
	)

protected

Gets the value for a tree.

First, GetNumLogs() is called to find out how many 16-foot logs the tree has. Then this uses the form class table for the tree's species to determine the number of board feet in the tree. It determines the first array index by rounding down to the nearest integer and subtracting 10 (with a max index of 30). The second index is equal to the number of logs minus 1. This pair of indexes gets us the volume in board feet of the tree from the form class table. This volume is multiplied by the value for the species and returned.

If the dbh is less than the minimum, the value is 0.

Parameters

fDBH	SORTIE's DBH value, in in
iSpecies	Tree's species.

Returns: Tree's value, in whatever currency units mp_fVal is in.

◆ PopulateTables()

void clMerchValueCalculator::PopulateTables ( )

protected

Populates the taper and form class board feet tables.

The table arrays are declared and the values populated according to the values in the documentation above.

◆ RegisterTreeDataMembers()

void clMerchValueCalculator::RegisterTreeDataMembers ( )

virtual

Registers the "Merch Val" float data member.

The return codes are captured in the mp_iVolumeCodes array.

Exceptions

modelErr if this behavior is being applied to any tree type except saplings, adults, and snags.

Reimplemented from clBehaviorBase.

◆ SetupGrid()

void clMerchValueCalculator::SetupGrid ( )

protected

Sets up the "Merchantable Timber Value" grid.

This ignores any maps.

Member Data Documentation

◆ m_cQuery

char* clMerchValueCalculator::m_cQuery

protected

String to pass to clTreePopulation::Find() in order to get the trees for which to calculate volume.

This will instigate a species/type search for all the species and types to which this behavior applies.

◆ m_iDBHIncs

short int clMerchValueCalculator::m_iDBHIncs

protected

Number of DBH increments in the taper table.

Equal to 16 (DBH in 2-in increments from 10 to 40 inches).

◆ m_iFormDBHIncs

short int clMerchValueCalculator::m_iFormDBHIncs

protected

Number of DBH increments in the form class board feet tables.

Equal to 31 (DBH in 1-in increments from 10 to 40 inches).

◆ m_iMaxLogs

short int clMerchValueCalculator::m_iMaxLogs

protected

The maximum number of logs a tree can have.

Equal to 6.

◆ m_iNumTotalSpecies

short int clMerchValueCalculator::m_iNumTotalSpecies

protected

Total number of species.

For the destructor.

◆ mp_fFormClass

double* clMerchValueCalculator::mp_fFormClass

protected

Form classes.

This is the proportion of DBH that the diameter is at the top of the first log. This is entered by the user as a percentage between 60 and 100 but to save math we convert to a proportion and subtract it from 1 so it's the inverse. Array size is # behavior species.
