1. Norwegian Water Information System: Vann-Nett An important tool in the Water Framework Directive (WFD) implementation A more Streamlined Water Management with GIS Lars Stalsberg, Norwegian Water Resources and Energy Directorate Line Fjellvær, Directorate for nature management

3. GIS in the Water Framework Directive Implementation of The Water Framework Directive (WFD) (2000/60/EC) initiated the development of a Norwegian GIS based Water Information System (Vann- Nett) to able to: implement the directive delineate water bodies (WB) add attributes to the WB present the data for the public Report the data to ESA/EU Handle a large number of geographical data (today 16400 WBs) Easy access to the WB which needs updating Easy access for all users to retrieve data on an object Easy to create statistics and maps for reports and the public

4. What is Vann-Nett? Vann-Nett consists of three different applications Vann-Nett Saksbehandler for executives who maintain WFD data (can be viewed by all stakeholders) Vann-Nett Innsyn which is created for all stakeholders who need easy access to WFD data Map Statistics Photos of WBs Vann-Nett Rapport which is a temporary application for fetching reports on all administrative levels Users ask for new reports which will be created in Crystal Reports as templates Vann-Nett both a Norwegian and an English version

5. Why ArcGIS Server in the WFD work? Our reasons for using an ArcGIS Server (AGS) and a multi-user ArcSDE database for Vann-Nett are that; All users work via the Internet in the same interface All users add data to the same central database (Oracle) All users can see all data in real time All users have got access to the same thematic datasets All users have access to templates for reports/statistics/maps Easy to centrally administer users, data and application Easy to add new data and templates to the users via the application Possible to hook up with other AGS, such as SFTs Vannmiljøsystem to fetch data in real time! In the future hook up to other AGS

6. The WFD data input Vann-Nett The users create new WB and update existing ones via the map interface or by using search engine

7. The WFD data output Vann-Nett Vann-Nett Public is used for data output on all administrative levels (Municipalities, counties, RBDA, Country) and for WBs Statistics on status and risk evaluation Statistics on different pressure, quality elements etc Detailed data on each WB

10. Presentation of data for Vann-Nett in maps

11. Heavily Modified Water Bodies

13. Thematic data No WMS for thematic data yet, because; Thematic data via WMS has a long response time in AGS When a server is down, response time even longer Not always a good legend for the data in the TOC This might be improved in AGS 9.3, but still a little early to see how this works in practice But, Vann-Nett has a service where users can add WMS locally! So, in Vann-Nett we use locally stored data (still) Gives good response time, but no updates from owners (of course, manual updates are no good solution) Geocache for vector and orthophoto works very fast and parks WMS totally Users are very concerned about response time As time and money allows we will look into new ways of displaying thematic data in Vann-Nett

14. Who is using Vann-Nett? Users of the Vann-Nett applications are (and will be): Executive personnel administering the WBs and the data Ministries and directorates Municipalities Press The public Eurostat, EEA, ESA and the EU NGOs and other organizations

15. The future development of Norwegian Water Information System (2009) Streamlining of database to be fully compatible with SEIS - WISE and reporting Access to all documents and plans relevant for the WFD work fetched via Web-service Connecting Vann-Nett and Vannmiljøsystemet (Water Environmental System) will be connected And more……

16. Conclusion Norwegian Water Information System improves water management because; All data in one place/accessible for all stakeholders Better coordination between authorities Easier reporting to WISE (SEIS) Data always updated No copying and sending needed Map interface makes it easy to find data (especially when all plans are connected to WBs) Can be used from anywhere via Internet More interesting presentation of data for the public and the press In short, a more fluent and improved water management is possible with GIS and Vann-Nett
