[GRASS-user] neutral landscape models

[Joel Pitt]

I was wondering if anyone has already implemented a grass module for
creating neutral landscapes as are often used in landscape ecology.

Particular interested in one with some kind of contagion parameter
(indicating the amount of clumping for landscape types). I know about
r.surf.fractal but this has no way of really indicating contagion
values.

e.g. something like:  http://research.esd.ornl.gov/realizer/
