NAME
     r.surf.fractal - GRASS module to create a fractal surface of
     a given fractal dimension.	 Uses spectral synthesis method.
     Can create intermediate layers showing the build up of
     different spectral coefficients (see Saupe, pp.106-107 for
     an example of this).

     Use this module to generate naturally looking sythetical
     elevation models (DEM).

Usage:
     r.surf.fractal out=name]

Parameters:
     Name of fractal surface raster layer to be produced Fractal
     dimension of surface (2 < D < 3) Default: 2.05 Number of
     intermediate images to produce Default: 0
