Hello Peter, could you tell us which modules you already used?
I had success with generating synthetic channels with r.texture, then running i.smap on those and the original data. Example for RGB orthophoto classification (with low efforts!): http://mpa.itc.it/markus/ortho_smap/ Here, we were only interested in a few classes (to investigate deer presence for accident mitigation) Markus Peter Freimuth wrote: > > Hallo GRASS User, > I am new in GRASS and have to find out for a project what GRASS can do > in regard to field boundary detection based on high resolution satellite > data.
