> By raster data I mean classified slope gradient (derived from a dem), landuse-landcover, lithology etc. A crosstabulation analysis will give me a table with the common areas for each class from each raster and this will go into other analysis. I can do it with other softwares (like ArcGIS DEsktop etc), but I would like to have all with numpy or to build something on top of numpy

I'm afraid also Zach does not understand what you are talking about
... So my first question (please bear with me) would be: What's a dem?
 (n/a in my dictionary)  And sorry for the cross-talk on the other
first post by you ...

And by slope gradient you mean second derivative?
