I have a very large and complex raster coverage produced from classified
satellite imagery that I would like to generalize.  What I have in mind
is not just simple mode filtering, but rather a process of simplification
and deletion based on polygon spatial characteristics and topology according
to a user-specified rule base.

I believe Lars Schylberg used exactly this technique with GRASS and shell 
scripts. My map, however, encompasses 9200 sq km at 25m res (3500 sq miles) 
and contains a tremendous number of polygons - not the sort of thing one 
processes using shell scripts on a SPARC 5/55.  Has Lars' work been developed
into some GRASS software?  Or, can anyone suggest some alternative methods?
