Hi Mohammed,

This seems to be an R topic rather than an OSGeo topic. The R-Geo 
mailing list is probably the best choice (look at the mailing list page 
on the http://www.r-project.org site). Random forest models can be used 
with data acquired by remote sensing, but the method is really aspatial 
in nature (the ability to deal with any autocorrelation, including 
spatial autocorrelation, is pretty limited in decision tree based 
methods, and random trees are an ensemble of decision trees, which 
create a "forest"). At this point, I'd do some more homework on decision 
trees (also commonly called classification and regression trees, or 
CART, models) so you have a better sense of the underlying concepts, and 
then hit the R-Geo mailing list if you have additional questions.
