sorry, i forgot to say which modules i used. first i did a unsupervised cluster classification and a false colour composit plus gps ground points to generate my training areas. after that i tried i.maxlik and then i.smap to get a better result but that also didn't satisfy me. i will also try some modification parameters, or generate more training areas. regards christian
