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. This problem is discussed in the context of cross-border web-based GIS applications which involve the combination of spatial data on the same type of real world(More)
The development of Geographic Information Systems (GIS) leads to integrated processing and storage of spatial data in raster and vector form. It is often desired that the raster data can be treated like the structured vector data. An object oriented management method of raster data is presented. One or more images and individual raster objects can be(More)
European initiatives like the European Water Framework (WFD) Directive and the Infrastructure for Spatial Information in the European Community (INSPIRE) Directive are dealing with cross-border issues. One of the best known examples of hazards that adhere strongly with cross-border aspects are floods, since water doesn " t stop at borders. In a cross-border(More)
SUMMARY The planning of road, railway, and subway tracks in urban environments is a manifold task because of complex legal, environmental, economic, and structural problems. However, skills and knowledge of the participants differ substantially and computer support for complex planning still is at its beginning. Especially computer-aided collaborative(More)
At Technische Universität München extensive official, forestal, climatological, touristical geodata and metadata on the unique ecosystem Bavarian Forest National Park were gathered since 1996 to set up a GIS-platform used for research projects as well as for education. To improve data availability of this precious datapool the GIS-platform has been(More)
