Had a look at your *.prj files and they indicate your shapefiles have geographic coordinates. If you want to make metric calculations - and a buffer is something like that - you should better define your shapefile with a projected coordinate system (e. g. Gauss-Krüger or UTM) and choose a projection for your project.
You can easily project you shapes with "save as ..." selecting a projection of your choice. regards, Christine -- View this message in context: http://osgeo-org.1560.x6.nabble.com/How-to-create-valid-new-shapefiles-with-qgis-and-a-buffer-around-tp5263763p5263799.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: http://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-user
