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
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
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
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 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
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
thematic data
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
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
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
