For acquisition of the 3D Building Model LiDAR-data are used as data basis as well as the building ground plans of the official cadastral map and a list of standardized roof shapes. The data management of the 3D Building Model is carried out by a central database with the usage of a nationwide standardized data model and the data exchange interface CityGML. On the one hand the update of the 3D Building Model for new buildings is done by terrestrial building measurements within the maintenance process of the cadastre. On the other hand the roofs of buildings which were built after the LiDAR flight and which were not measured terrestrially yet, are captured by means of picture-based digital surface-models derived from image-matching of oriented aerial photographs (DSM from image matching).

In einer Forschungskooperation der Bayerischen Vermessungsverwaltung mit dem Lehrstuhl für Geoinformatik an der TUM wurde ein auf dem AdV-CityGML-Profil basierender Testdatenbestand des bayerischen LoD2-Gebäudebestands in ein INSPIRE-konformes Datenschema transformiert. Als Grundlage für eine derartige Transformation stehen von der AdV der Produktstandard, ein Prüfplan für 3D-Gebäudemodelle sowie eine Mapping-Tabelle zur Verfügung. Im Rahmen des Forschungsvorhabens wurde untersucht, ob die in der Mapping-Tabelle festgeschriebenen Transformationsregeln eindeutig und hinreichend für die Implementierung einer Transformation von LoD2-Daten gemäß dem AdV-Produktstandard nach INSPIRE sind. Der praktische Nachweis der Transformierbarkeit der 3D-Gebäudemodelle in das INSPIRE-BU-Thema wurde durch die Transformation von Produktionsdaten des bayerischen 3D-Gebäudemodells im LoD2 erbracht. Zur Qualitätssicherung der zu transformierenden Daten wurden die Prüfspezifikationen nach dem Prüfplan für 3D-Gebäudemodelle der AdV verwendet. Die Mapping-Tabelle der AdV wurde auf Vollständigkeit und Richtigkeit überprüft und ergänzt. Summary The federal governments of Germany endeavour to create a harmonized 3D building data set based on a common application schema (the AdV-CityGML-Profile). In a joint research project, the Bavarian Agency for Digitisation, High-Speed Internet and Surveying and the TUM, Chair of Geoinformatics, transformed an AdV-CityGML-Profile based test data set of Bavarian LoD2 building models into an INSPIRE-compliant schema. For the purpose of a transformation of such kind, the AdV provides the data specification, a test plan for 3D building models and a mapping table. The research project examined whether the transformation rules defined in the mapping table were unambiguous and sufficient for implementing a transformation of LoD2 data based on the AdV-CityGML-Profile into the INSPIRE schema. The proof of concept was carried out by transforming production data of the Bavarian 3D building model in LoD2 into the INSPIRE BU schema. In order to assure the quality of the data to be transformed the test specifications according to the test plan for 3D building models of the AdV were carried out. The AdV mapping table was checked for completeness and correctness and amendments were made accordingly.

Zusammenfassung Zur Erstellung von landesweit flächendeckenden 3D-Gebäudemodellen sind die Geobasisdaten der Vermessungsverwaltungen der Länder unverzichtbar. Anhand der Gebäudemodellierung des bundesweit einheitlichen Amtlichen Liegenschaftskataster-Informationssystems (ALKIS®) wird dargestellt, welchen Stellenwert das Liegenschaftskataster zukünftig bei 3D-Gebäudemodellen einnehmen kann. Am Beispiel Bayerns wird der Aufbau eines landesweiten Gebäudemodells im Level of Detail (LoD) 1 und 2 aufgezeigt. Auf Basis vorhandener Geobasisdaten wird ein vollautomatischer Herstellungs-und Fortführungsprozess für ein einfaches Klötzchenmodell (LoD 1) vorgestellt. Für den LoD 2 werden die Synergieeffekte zwischen 3D-Gebäudemodellen und dem Liegenschaftskataster erläutert. Summary For the production of statewide 3D-building models, the basic geodata of the surveying authorities of the Länder are essential. The potential and the value of the real estate cadastre become obvious when regarding the official modeling guidelines of the germanwide standard Amtliches Liegenschaftskataster-Informationssystem (ALKIS®). The production of statewide 3D-building models in Level of Detail (LoD) 1 and 2 is shown by the example of the Land of Bavaria. Based on available basic geodata a fully automatic production and updating process was developed. The publication illustrates this process, its functionality is explained by the example of a simple 3D-building-cube (LoD 1). Concerning LoD 2 the synergies between 3D-building models and the real estate cadastre are described.
