Wednesday, March 10
Dr. Werner Kuhn, Dr. Yaser Bishr, Dipl.Geogr. Ann Hitchcock, OGC
Technical Operations Europe and University of Münster, Germany
8.30-12.00
Open GIS Consortium (OGC) abstract specifications for interoperable geoprocessing have been subdivided into "books" which together form OGC's "bookshelf". The tutorial presents, from a European perspective, the current status and plans for further development of these books. The booksÕ content will be presented in three parts. Part one covers those topics where implementation specifications are already accepted or currently requested. Part two covers requests for implementation specifications which are being prepared. Part three discusses remaining themes.
Wednesday, March 10
Dr. Arne J. Berre, SINTEF Telecom and Informatics, Norway
8.30-12.00
The first part of the tutorial discusses general problems and solutions for syntactic and semantic interoperability in the context of IT-standards, such as ISO RM-ODP, ISO CSMF, CORBA/EJB/COM+, UML and XML. The second part presents status and progress, and the use of IT-standards within the ISO/TC211 15046 standard (Geographic Information/Geomatics). The third part presents practical experiences with the use of ISO/TC211 and OpenGIS interoperability approaches in the European DISGIS Esprit IV project.
Wednesday, March 10
Dr. Dave Abel, CSRIO, Australia
8.30-12.00
The tutoral discusses strategies and system architectures for large-scale information systems with heterogeneous components, considering techniques developed in fields such as Digital Libraries and Electronic Marketplaces as well as Spatial Information Systems. Spatial Data Infrastructures at a regional scale are used as a case study to convey the central issues, and some proptotype systems developed by CSIRO will demonstrate their application.
Friday, March 12
Dr. Martin Huber, GeoTask, Switzerland
14.00-17.30
The tutorial introduces the object-relational concepts and related geographic extensions (e.g. OpenGIS simple features for SQL). It will be demonstrated how interoperability in the Intranet and Internet can be achieved by using the JDBC-interface and Java technology, as well as application server middleware.
Friday, March 12
H. R. Gnägi, ETH Zürich, Switzerland
14.00-17.30
A simple geometry supporting data description language and a complete tool chain - transfer from the conceptual level to bits and bytes - are presented . The workshop introduces a modeling-based approach which utilizes a conceptual schema language to describe the data structure. A set of rules is also introduced which allows for automatic derivation of corresponding transfer formats based on the data description. The principal concepts behind the INTERLIS mechanism will be presented, linking a graphical data description by UML to physical ITF- or XML-formatted data.
