Detailed Description

The SpatialAnalysis class is the scripting class related to extra spatial analysis functions.

rumpleIndex: ratio crown surface area / ground area for the whole project area. saveRumpleGrid(): save RU-based grid of rumple indices to an ASCII grid file.

Member Function Documentation

addToScriptEngine()

void SpatialAnalysis::addToScriptEngine ( )

static

extractPatches()

QList< int > SpatialAnalysis::extractPatches	(	Grid< double > &	src,
		int	min_size,
		QString	fileName
	)

extract patches ('clumps') and save the resulting grid to 'fileName' (if not empty).

extract patches (clumps) from the grid 'src'.

Returns a vector with the number of pixels for each patch-id

Patches are defined as adjacent pixels (8-neighborhood) Return: vector with number of pixels per patch (first element: patch 1, second element: patch 2, ...)
