Norwegian Water Information System: Vann-Nett

An important tool in the Water Framework Directive (WFD) implementation

A more Streamlined Water Management with GIS

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

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

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

The WFD data input Vann-Nett

  • The users create new WB and update existing ones via the map interface or by using search engine

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

Presentation of data for Vann-Nett in maps

Heavily Modified Water Bodies

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

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

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……


  • 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
