GDI NRW and GEOBASIS.NRW:Common Manifesto for Interoperability

Northrhine-Westfalia is building together with its communities, the GIS industry and the GIS users the Geo-Data Infrastructure NRW (GDI NRW), in order to activate the geo-information market in NRW and to improve the administrative and private geo-data within the framework of existing legislation. In this process a freely accessible geo-data net for all the partners with a central clearing point giving access to all geo-data available in the net will be established. In the GEOBASIS.NRW project the standard for an official cadastre information system (ALKIS) which was developed by the Working Committee of the Survey Administrations of the Länder of the Federal Republic of Germany (AdV), is being put into practice in Northrhine-Westfalia. The essential aim is a wider use inside and outside the communities of the geo-basis data provided by ALKIS. The project helps to improve the performance of the communities and is closely related to the setting up of the GDI NRW. The basis for the two projects GDI NRW and GEOBASIS.NRW will be the specifications of the Open GIS Consortium, developed and supported by all leading GIS producers, and the related practice-orientated interoperability concept for user software. This is supposed to enable a vast variety of GIS applications by different producers to have access to geo-basis data in geo-data servers at different places and by different producers at the same time, to use and - if it serves the professional purpose and if it is legal - to change them. Due to the heterogeneous system situation, Northrhine-Westfalia is an ideal test-bed for the demonstration of OpenGIS in the above mentioned areas of application.

Start of the initiative with sponsored projects Result: pre-GDI (realization of OGC or ISO specs) Market study Reference model

Setup Special Interest Groups (bottom up) SIG Architecture

IT is in progress (e.g. SOAP, UDDI, ...) OGC Specs are under further development

(e.g. Catalog vs. WRS) Harmonization of ISO and OGC

SIG Metadata SIG E-Commerce Result: Concrete concepts for GDI NRW

Start Pilot / Testbed Result: first instance of GDI NRW OGC-Pilot: Integration of different sets of geodata to realize

a real world use case: “Baulandkataster” for the city of Cologne

Guide the process from a board (in the near future CeGI)

Experiences ...

Substantial challenges of a NSDI: Create awareness Make documentation available Bridge cultural differences Find people who share the vision and realize it,

not only politicians and strategists – also „doers“

Things to avoid: Unclear definition of results Missing participation of the private sector Frictions between providers Low financing
