xdem.DEM.fractal_roughness#
- DEM.fractal_roughness(window_size=13)[source]#
Calculates the fractal roughness, the local 3D fractal dimension. Can only be computed on window sizes larger or equal to 5x5, defaults to 13x13. Output unit is a fractal dimension between 1 and 3.
Based on: Taud et Parrot (2005), https://doi.org/10.4000/geomorphologie.622.
- Parameters:
window_size (
int) – The size of the window for deriving the metric.- Raises:
ValueError – If the inputs are poorly formatted.
- Return type:
TypeVar(RasterType, bound= Raster)
