New Product Announcement - Updates for Administrative Boundaries VG250 and VG1000
The Administrative Boundaries VG250 and VG1000 have been updatd with full integration into the Digital Landscape Models DLM250 and DLM1000. The datasets are immediately available in the version 31.12. 2005.
With the objectives to improve quality and to increase compatibility with other official geodata the products were further developed as to content and form. The course of the administrative boundaries was matched to the geometry of the other objects contained in the DLM250 and DLM2000, respectively.
The hierarchical structure of all administrative levels is represented as a result of the introduction of the regional key (RS-Regionalschlüssel). For update-processing the official municipality key (AGS - Amtlicher Gemeindeschlüssel) is still kept in the relevant data, which is derived from the RS by omitting the administrative community.
“RS” and “AGS” constitute the keys referring to the products of the Statistical Offices of the Federal Government and the Länder (states). Integration of statistical data or data synchronization are thus easily feasible (please see also www.destatis.de). The attribute “SHN” is a modified codification of the regional key. It establishes the link to the product EuroBoundaryMap (EBM) of EuroGeographics which is used, among others, at the European Authority Eurostat.
The “ArcInfo Personal Geodatabase” is now also available as a new data output format, the format “ArcInfo-Generate” no longer demanded having been dropped.
Representation of the administrative areas has ended until now at the coast line. With the integration into the Digital Landscape Models these areas are extended to the sea area (12 miles zone). Thus, administrative areas are created which include both landed and water areas. For the purpose of distinction the attribute “GF” has been introduced.
Hint on the special representation of Lake Constance:
There exist no agreements on the course of national borderlines between the adjoining states Germany (Bavaria and Baden-Württemberg), Austria and Switzerland concerning the Lake Constance area (Hoher See between Bregenz and Constance). The adjoining states have defined areas that come under the responsibility of the respective state. To illustrate and explain this situation new values have been introduced for the “USE” attribute.
