[GRASS-dev] wish: r.neighbors with Gaussian kernel average

Hi,

it would be nice to have a Gaussian kernel average in r.neighbors to
take care of the distance to the central pixel in the moving window.

I see that in v.kernel relevant functions might be already available:
http://trac.osgeo.org/grass/browser/grass/trunk/vector/v.kernel/function.c
but I am not sure which of them is the right one.

Having this Gaussian average will be simpler than defining a custom weights
matrix.

Opinions?

Try r36892 (7.0).

Great, backported to 6.5.
