"WebSep 1, 2024 · The neighbourhood slope algorithm or Horn’s method [43] is used to solve the surface slope. In Horn’s method (Horn(1981)) the nearest points are weighted more than diagonal neighbours. This method is also known as the Sobel operator [44]. An area characterized by high slope variations seems to benefit the most from Horn algorithms. " - Neighbourhood slope algorithm
