This division of Germany into major natural regions takes account primarily of geomorphological, geological, hydrological, and pedological criteria in order to divide the country into large, physical units with a common geographical basis. Political boundaries play no part in this, apart from defining the national border. In addition to a division of Germany by natural regions, the federal authorities have also produced a division by so-called landscape areas (Landschaftsräume) that is based more on human utilisation of various regions and so has clearly different boundaries.
