A CORBA-based Approach to Data and Systems Integration for 3 D Geoscientific Applications

Today’s geo-information systems are not open enough to provide a required level of data and systems integration. In this paper we introduce an approach to dataand systemintegration which is based on the common object request broker architecture (CORBA), which allows for various applications to exchange data as objects. As a result not only data but also data processing methods can be made accessible for the remote applications thus creating a basis for exchange of geo-services. The central role in the proposed approach plays an objectoriented geodata store built on top of common object model: objects which are uniformly stored in the database serve as mediators between extremely heterogeneous representations inherent to different geo-scientific applications. The approach is evaluated by the development of a prototype distributed environment for concrete geological and geophysical 3D modeling systems.
