The AAA model as contribution to the standardisation of the geoinformation systems in Germany
Seifert, Markus
Germany is a classic example of a country that takes great pride in itts highly accurate maps and cadastral data. In the last three decades several independent geoinformation systems has been developed in the field of cadastre and topographical mapping. Right now a redesign of the German digital cadastral information system ALK (Automated Real Estate Map) is under development. The new approach - called ALKIS (Official Cadastral Information System) - was launched in order to harmonize the structures of ALK and the topographic database ATKIS on the one hand and to integrate the cadastral map and the land titles into one single model which was usually separated for historical and technical reasons. Adding also the geodetic reference points (AFIS) almost all official data of the surveying and mapping agencies are defined in a common and harmonized data model, called the AAA data model (AFIS-ALKIS-ATKIS Data Model). For that reason the Working Committee of the Surveying Authorities of the States of the Fedaral Republic of Germany (AdV) has started developing a new conceptual data model based on international GIS standards which help to fulfill this harmonization. That will bring the surveying and mapping agencies in Germany to a nation wide well defined data that can be used as a baseline for many other thematic application schemas. For the inreasing efforts in building up a apatial data infrastructure the AAA data model can generally be used for standardization of these thematic data as well and could help to standardize the Geoinformation in Germany brick by brick.
