The latest important changes

1. Databases actualized on level 5th Sept. 2011 (Reform in Mecklenburg-Western Pomerania).
2. Most likely postal codes added to telephon preselections.
3. Added data tables with information of the Official Topographic Maps.
4. New database table with the Snow and Wind Load Zones.
5. New database table with Nature Area Classification and Landscapes.

Brief description

The database tables contain geodata of the Federal Republic of Germany with georeferenced towns, municipalities, town quarters and other administrative units, postal codes, telephone preselections and nature areas, landscapes and climatic zones. The database also contains register of the official topographical cartographies of the Federal Republic of Germany with map names and map numbers, corner coordinates and supplemental data. The data contain coordinates for navigation and geo-coding, proximity searches and distance computations and are prepered for the spatial mapping of environmental information. The information is available in different database tables, witch can be linked together by included keys.

Quite often it is necessary to reference an address field e.g. like town or municipality name, postal code or telephone preselection, to corresponding geographical data and coordinates - a Geo Reference. The georeference can be used for example to direct a customer to the closest store locations of a retail store chain by doing a proximity search. Another possibility it to determine distances between the different objects of the database tables with the included georeferences. With the elevation data from a Digital Elevation Model the ground level height of each place can be determined. Often the knowledge is necessary about affiliations and relationships between data derived from different hierarchies. So it can be determined to which federal state, governmental area or governmental county a town, a postal code or a telephone preselection is associated.

It is possible to assign a variety of natural and scenic information to each town or municipality. The snow and wind load zones are available as local climatic data. In conjunction with the ground level heights they can be used to calculate static loads for the planning of building constuctions.
