SDG

SDG stands for Second Derivative in direction of Gradient. It is a very interesting operator, particularly to people working in the UNCLOS margins extension program. Shortly, it is the UN recommendedalgorithm to determine the Foot Of continental Slope (FOS). Even if you do not know what I am talking about, this operator worth trial because it has the ability to reveal very concealed trends in your data. It also depends on the smoothing parameter p as the previous option.
