A CORBA-based Approach to Data and systems Integration for 3D Geoscientific Applications~1

摘要

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