Thank you Niko, well I understand the first one (using v.extract). -Is it possible to do something like that using v.out.ogr and export to shapefile? -As far as concerns the second question using v.to.rast, how can I export only specific areas using sql where clause or list for specific categories? Thanks again, Leonidas
