Hello I have merged three CORINE vector maps for coniferous, broad-leaved and mixed forests in order to create one general map for all forests as I need to calculate the length of the forest edges.
After using v.patch (with flag e) to merge the maps I have tried my best to remove all lines lying inside of boundaries so that only the outer boundaries would be left - with no luck. The main problem should be that the adjacent boundaries from the three maps have only been put next to another and not really "merged" (this is not a problem concerning double boundaries). Does anyone know how to cope with this? I have not been able to find any posts regarding this problem and would really appreciate your help. I am working with GRASS 6.4.0+42329 (2010) on Ubuntu Thanks, Arne http://osgeo-org.1803224.n2.nabble.com/file/n6505270/inner_lines.png -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Removing-inner-lines-in-merged-vector-map-tp6505270p6505270.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
