Class: QgsTotalCurvatureFilter

class qgis.analysis.QgsTotalCurvatureFilter

Bases: QgsNineCellFilter

Calculates total curvature as described by Wilson, Gallant (2000): terrain analysis*

Methods

processNineCellWindow

Calculates total curvature from nine input values.

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

Calculates total curvature from nine input values. The input values and the output value can be equal to the nodata value if not present or outside of the border. Must be implemented by subclasses*

Return type

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