Hello Guillermo, thanks for your fast reply. I have to say that I am not working with rasterfiles in this case! All my data is vectorbased and if I am working in the gvSig envirmonment I know hao to add a field to a attribute table of my layers and to calculate something, e.g. Area. But I want to work in the Modelbiulder environment and my Layer is a result of , e.g. Difference, Merge etc. In ArcGis it is also just possible to add a field to a Layer but there we can say Make feature Layer which is not as far as I see it possible in the Modeler of Sextante to finally add a field to the attribute table of my result Merge or Difference. So just imaginge two vector layers that I want to difference from each other and then add a field to the result to calculate the new area. And here is the next question if it is possible to calculate a field in the attribute table if you are working in the modeler environment?
Thanks a lot David -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Sextante-extension-question-tp3054318p5026303.html Sent from the gvSIG international mailing list archive at Nabble.com. _______________________________________________ Gvsig_internacional mailing list [email protected] http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional
