ATKIS® Basis DLM Update, October 2009
On 21 October 2009 updated data for the Basis DLM (old data model) were adopted for distribution from all Länder (states of the Federal Republic) except for Nordrhein-Westfalen and Schleswig-Holstein.
For Nordrhein-Westfalen and Schleswig-Holstein that have already completed changeover to the new AAA® data model, updated data are available according to the AAA® specification, which are presently distributed exclusively in the product specification "Basis DLM (AAA® compact)" in NAS format.
The data contained in the nationwide Basis DLM (old data model) of those Länder having already implemented the model change, have the status of topicality of the date of the model change and will undergo no more updates. This particular situation of parallel data distribution within two different data models of different topicality will persist until the date at which all Länder will have implemented the model change.
You can find more detailed information on data topicality in our metainformation system under the products “Digital Basis Landscape Model Basis DLM or Basis DLM AAA® (available shortly), category data quality”. For the Länder working already in the AAA® data model, topicality concerning the last data still available in the old data model mode can be inquired at the GeoDataCentre of the Bundesamt für Kartographie und Geodäsie (Federal Agency for Cartography and Geodesy).
You will find further information also under the heading Digital Landscape Models of Germany.
Please contact our Geodata Distribution Center for any further advice and information on the products.
