10. RSDI WS JRC Ispra, Jan. 2003 Lars Bernard, Gerd Buziek, Markus Müller, Clemens Portele, Jens Riecken In der Initiative GDI NRW realisieren das Land NRW, Kommunen, IT-Unternehmen, Forschungseinrichtungen und Nutzer von Geoinformationen in Form eines Public-Private-Partnerships eine Geodateninfrastruktur, um den Geoinformationsmarkt in NRW zu aktivieren und die Nutzung der behördlichen und privaten Geodaten im Rahmen der gesetzlichen Möglichkeiten zu verbessern. Unter Geodateninfrastruktur versteht die Initiative ein offenes Geoinformationsnetz, das Geodatenproduzenten, Geodatenveredler sowie Geoinformationnutzer verbindet und so den Zugang zu allen verfügbaren Geodaten und Geoinformationsdiensten ermöglicht. Insbesondere soll ein problemloser Zugang zur Nutzung und marktwirtschaftlichen Wertschöpfung auf der Basis von behördlichen und privaten Geoinformationen gewährt werden. Dazu werden alle relevanten Geoinformationen der Behörden, Kommunen und privaten Anbieter verbunden und über das Internet verfügbar gemacht. Grundlage für die Initiative GDI NRW sind die Spezifikationen des Open GIS Consortiums und das damit verbundene dienstebasierte Interoperabilitätskonzept für Anwendungssoftware. Zur Erreichung dieses Ziels werden 1. Application of the Open GIS and ISO/TC 211 standards wherever they are available – To avoid special solutions 2. Clear specifications for all services and information products within GDI NRW and GEOBASIS.NRW – Basis for interoperability 3. Exactly one specification for a service or an information product – Guarantee of interoperability 4. Specifications are realized on implementation level – Interoperability of the applications, not of the underlying concepts Die Aktivitäten der Initiative GDI NRW dienen in erster Linie der Entwicklung der Geodateninfrastruktur in Nordrhein-Westfalen, d.h. der praktischen Entwicklung der hiesigen Infrastruktur unter Berücksichtigung der hier relevanten Erfordernisse. Die Entwicklung dieser regionalen Geodateninfrastruktur kann allerdings nur sinnvoll im Kontext der entsprechenden Entwicklungen auf nationaler, europäischer und globaler Ebene geschehen. Aus diesem Grunde wird die Initiative GDI NRW entsprechende Entwicklungen in anderen Bundesländern wie auch auf der nationalen und internationalen Ebene aktiv unterstützen und sich um eine Konsensbildung und Harmonisierung bezüglich der zugrundeliegenden fachlichen und technischen Konzepte bemühen. Common manifesto on interoperability of GDI NRW (MoU)

24. RSDI WS JRC Ispra, Jan. 2003 Lars Bernard, Gerd Buziek, Markus Müller, Clemens Portele, Jens Riecken Example: Chaining distributed Web Feature Services nDuring the storm disaster in the German state Baden-Wuerttemberg in 1999 (storm Lothar) approximately 2 million solid cubic meter wood were felled by the storm. Primarily old trees were affected. After such an event the parts of the road network are to be identified, which are to be examined urgently whether they must be cleared if necessary: nShow me all roads crossing forest areas, whose age classification is higher than 80 years.

Successful Bottom-up approach ! How to keep this organization form stable ? nInteroperability works only at the technical level. Convincing use cases are missing nAwareness concerning interoperable GI-Services is (still) missing: Need for more teaching modules on GI-Services
