Hi Manuel, I also suggest you to consider the analysis tools provided by Sextante [1]. It offers "bridges" to other GIS analysis software, like GRASS and SAGA, and they have a lot of analysis functionalities and algorithms. For example GRASS has the r.li.* [1 ]set of commamds for landscape analysis.
