Detailed Description

Relative height averaging method averages the values based on range defined relative to bed elevation or surface (when countedFromTop())

The range is defined in the same length units as defined by model (e.g. meters)

if countedFromTop(), the method represents averaging based on depth below surface. For example one can pull out results for between 6 to 12 meters below the water surface - depth from 6m to 12m. The depth will be truncated at the bed level.

if not countedFromTop(), the method represents averaging based on height above bed level. For example one can pull out results for between 6 to 12 meters above the bed - height from 6m to 12m. The height will be truncated at the bed level.

Constructor & Destructor Documentation

QgsMeshRelativeHeightAveragingMethod() [1/2]

QgsMeshRelativeHeightAveragingMethod::QgsMeshRelativeHeightAveragingMethod

(

)

Constructs default depth averaging method.

Definition at line 482 of file qgsmesh3daveraging.cpp.

QgsMeshRelativeHeightAveragingMethod() [2/2]

QgsMeshRelativeHeightAveragingMethod::QgsMeshRelativeHeightAveragingMethod	(	double	startHeight,
		double	endHeight,
		bool	countedFromTop
	)

Constructs the depth/height averaging method.

Parameters

startHeight	starting depth/height, higher or equal than 0
endHeight	ending depth/height, higher or equal than startDepth
countedFromTop	if true, the startLength and endLength is relative to surface (0 is surface level). if false, the startLength and endLength is relative to bed (0 is bed level).
