Slope calculation as steepest downward slope on planar triangular facets

[debpal]

Kind of request

Adding new functionality

Enhancement Description

I have seen a slope function 'pyflwdir.dem.slope'. But it seems to me like slope of D8 flow direction. I need to calculate the slope of D-inf flow direction. I guess some changes in the code of 'pyflwdir.dem.slope' can calculate slope of D-inf flow direction. I don't understand how to do. Could someone help me please?

Thanks for your request.
The slope is calculated using 2nd order partial derivatives.

Pyflwdir only supports D8 flow at this time, and there are currently no plans to add D-inf flow. I would however be open to suggestions how to implement this from the user community.
