Detailed Description

loads (initializes) trees for a "stand" from various sources.

StandLoader initializes trees on the landscape. It reads (usually) from text files, creates the trees and distributes the trees on the landscape (on the ResoureceUnit or on a stand defined by a grid).

See http://iland-model.org/initialize+trees

loadDistributionList()

int StandLoader::loadDistributionList	(	const QString &	content,
		ResourceUnit *	ru = NULL,
		int	stand_id = 0,
		const QString &	fileName = ""
	)

worker function to load a file containing rows with dbhclasses

initialize trees on a resource unit based on dbh distributions.

use a fairly clever algorithm to determine tree positions. see http://iland-model.org/initialize+trees

Parameters

content	tree init file (including headers) in a string
ru	resource unit
fileName	source file name (for error reporting)

Returns

number of trees added

loadiLandFile()

int StandLoader::loadiLandFile	(	const QString &	fileName,
		ResourceUnit *	ru = NULL,
		int	stand_id = 0
	)

load a tree distribution based on dbh classes. return number of trees loaded.

loadPicusFile()

int StandLoader::loadPicusFile	(	const QString &	fileName,
		ResourceUnit *	ru = NULL
	)

load a single tree file (picus or iland style). return number of trees loaded.

loadSaplings()

int StandLoader::loadSaplings	(	const QString &	content,
		int	stand_id,
		const QString &	fileName = QString()
	)

a (hacky) way of adding saplings of a certain age to a stand defined by 'stand_id'.

loadSaplingsLIF()

int StandLoader::loadSaplingsLIF	(	int	stand_id,
		const CSVFile &	init,
		int	low_index,
		int	high_index
	)

loadSingleTreeList()

int StandLoader::loadSingleTreeList	(	const QString &	content,
		ResourceUnit *	ru = NULL,
		const QString &	fileName = ""
	)

worker function to load a file containing single trees

load a list of trees (given by content) to a resource unit.

Param fileName is just for error reporting. returns the number of loaded trees.

processAfterInit()

void StandLoader::processAfterInit

(

)

this function is called after the init and after initial LIF-calculations.

processInit()

void StandLoader::processInit

(

)

main function of stand initialization the function loads - depending on the XML project file - inits for a single resource unit, for polygons or a snapshot from a database.

main routine of the stand setup.

setInitHeightGrid()

void StandLoader::setInitHeightGrid ( const MapGrid *  height_grid )

inline

set a constraining height grid (10m resolution)

setMap()

void StandLoader::setMap ( const MapGrid *  map )

inline

define a stand grid externally
