Hello Markus, thank you for your advice. Unfortunatly its not possible for me to get clean data. If I import an esri file (16 features) with the command v.in.ogr -o (the o flag is for the locations projection) I get a file with 58 features. Below I attached the output:
Best regards v.in.ogr -o dsn=/home/BL2009/Bundeslaender.shp output=test4 Over-riding projection check Layer: Bundeslaender Importing map 16 features...
