Dear Jeffrey Evans,
I have a question about a value in the HLI formula you wrote in the PDF, where you describe the Geomorphometry & Gradient Metrics toolbox for ArcGIS (https://github.com/jeffreyevans/GradientMetrics/blob/master/READ%20ME.pdf).
In your PDF the formula for HLI appears like this:
HLI = 0.039 + [0.808 ∗ cos(𝑙) ∗ cos (𝜃)] − [0.196 ∗ sin(𝜃)] − [0.482 ∗ cos(𝑓(𝛼)) ∗ sin(𝑓(𝛼))]
Then you cite McCune & Keon, 2002, as they are the authors of the formula. But, I see that in Table 2 of McCune & Keon, 2002 the value is different, i.e., 0.339.
I would assume this may be a typo in your PDF document, right?
This I just spot last week thanks to a very friendly and detailed review I got from a paper I submitted. I am using some of your metrics in my research.
Best, Paola
