Hopefully someone of you can help me:
I need to run a kernel density function as distance weighted function
that uses a given attribute. Locations are given as points and the
weight is given in a column. As far as I see, this is not possible with
v.kernel (Manual: "LIMITATIONS The module only considers the presence of
points, but not (yet) any attribute values."). But some presentations
speak of 3D-kernel functions, e.g.
Searching the web I saw the following solution using R:
would prefer to keep the solution inside the GRASS workspace.
Is there an addon I don't know of? Or does anybody have an alternative
