Hi Mark, hi all,

currently I am searching for a GRASS module to calculate
the fractal dimension of remote sensing images. I think
the box counting method should be fine for that.
So I have a few questions (as not being very experienced with fractals
in GIS yet):

 - I would need a module which accepts grey scale images instead
   of binary images
 - the result should be regionalised: A resulting raster map would show
   the distributed fractal dimension so that you could distinguish
   different types of landscape

Is that possible with (modified) r.boxcount? Or do I have to write a
new module? 
Does anybody have experience here?

Any help is appreciated!
