Abstract

Geological maps constructed in a conventional way may have deficiencies for several reasons: The editor might not be able to integrate all available information into the 3D model, there might be no possibility to control all aspects of consistency and plausibility of the 3D model because of its geometric complexity and/or, finally, the exploration of all spatial consequences within the 3D model is a tedious task.

We present an interdisciplinary approach of computer scientists, geophysicists and geologists to implement an integrated application of an object oriented database system (OODB) and geological and potential field 3D modeling software. Spatial distribution and heterogeneity of the platforms used requires the deployment of Object Management Architecture (OMA).

Thereby the utilized software tools become compliant to Object Request Broker (ORB) technology and the geoscientific 3D modeling software will get direct access to the OODB.

The study area is located in southern Lower Saxony, Germany. A high density of well information, several isosurface maps, and a great number of geophysical surveys combined with the iterative exchange of the 3D geometry between geological and geophysical modeling tools leads towards the construction of a consistent 3D model.
