[GRASS-dev] [GRASS GIS] #3269: r.roughness.vector: bug in rescale formula

[Blumentrath, Stefan]

Hi,

Another related question: There are now two AddOns for this purpose:

r.roughness.vector (last changed 2 years ago)

and from 2016: r.vector.ruggedness

Both basically calculate the same metric(s), though they have their differences and both have their pros:
r.roughness.vector offers more advanced options (esp. useful for multi scale application)
r.vector.ruggedness uses parallelization

Having two modules for one task / metric, which are not conceptually different is a bit confusing...
IMHO both should be merged into one, keeping the strength of each of them...

Other thoughts?

Cheers
Stefan

 There is a little bug in the formula that produces the "Fischers K" output  (line 317).
 "- 1" should not be in there.
