[GRASS-user] [Fwd: GIS models]

[Michael Barton]

Look in the wildfire modeling modules (e.g., r.ros). These represent a type
of anisotropic diffusion algorithms. I've used them to model Viking sea
faring with some success.

It would be more useful for things other than fires if there were a more
generic form of anisotropic diffusion to work with.
