SUMMARY The paper addresses current research issues in the field of interoperability of heterogeneous GI systems. Special emphasis is placed on heterogeneity at the level of conceptual data models – a problem that becomes particularly evident in a cross-border context. A concept of a Model Driven Approach for accessing distributed, heterogeneous spatial data using web services currently being developed in a joint research of the Eidgenossische Technische Hochschule (ETH) Zurich, the Technische Universitat Munchen (TUM), the Bundesamt fur Kartographie und Geodasie (German Federal Agency for Cartography and Geodesy) and the Swisstopo (Swiss Federal Office of Topography) is presented. This approach is based on the fundamentals of Service Oriented Architecture (SOA), the Model Driven Approach (MDA) and semantic transformation. This paper concentrates on the design of a web service with the ability to perform semantic transformation at the conceptual schema level. The service interface is discussed by means of a use case.
