Class: QgsRuggednessFilter

class qgis.analysis.QgsRuggednessFilter

Bases: QgsNineCellFilter

Calculates the ruggedness index based on a 3x3 moving window.

Algorithm from Riley et al. 1999: A terrain ruggedness index that quantifies topographic heterogeneity

Methods

processNineCellWindow

rtype Tuple[float, float, float, float, float, float, float, float, float, float]

processNineCellWindow(self) → Tuple[float, float, float, float, float, float, float, float, float, float]

Return type

Tuple[float, float, float, float, float, float, float, float, float, float]
