The three basic water system databases in Norway are –
- The Catchment Database (REGINE) link
- The Lake Database link
- The River Network Database (ELVIS) link
The Lake Database and ELVIS are established by extracting data from Norway’s Main Map Series N50 Kartdata (accuracy matching map scale 1:50 000), produced by the Norwegian Mapping Authority. REGINE’s catchment boundaries are compiled according to contour lines and the water system defined in N50 Kartdata.
The three databases contain the National Identification Numbers for catchments, lakes and rivers, as well as attribute tables with relevant information.
Other geodata provided by NVE, related to the water system: an established & planned hydropower system, flood inundation zones, river systems protection against hydropower exploitation, hydrological monitoring stations etc.
The water system databases are available at NVE Atlas (atlas.nve.no).
Energy Resource Data
NVE maintains, presents and distributes geographic data for developed hydropower in Norway, i.e. hydropower plants, reservoirs, water tunnels/pipes and water intake locations, as well as catchments for all areas were the runoff is used for hydropower production. Geodata for established/planned wind farms/turbines are also established. NVE has geodata for transmission lines as well as the concessionary area including the responsible grid company.
The energy resource data are available at NVE Atlas (atlas.nve.no).
Landslide Data
NVE has the overall national responsibility for the prevention of landslide accidents. This includes defining a mapping plan for landslides/debris avalanches, rockfalls, rock avalanches, rockslides, snow avalanches and areas vulnerable to quick clay slides. The Norwegian Geological Survey (NGU) is responsible for the National Landslide Database, in Norwegian Skreddatabasen, in which all data on avalanches are systematized and compiled in various databases. Historical landslides are included in the Event Database (NGU), containing data mainly collected from NGU, the Norwegian Geotechnical Institute (NGI), the Norwegian Public Roads Administration (Statens vegvesen/SVV), the Norwegian National Rail Administration (Jernbaneverket/JBV) and The Norwegian Military Geographic Service (Forsvarets militærgeografiske tjeneste/FMGT). Hazard zone maps concerning rock avalanches, snow avalanches and landslides have not yet been compiled systematically on a national basis (May 2011).
The landslide data are available at Skrednett (www.skrednett.no).
Map Applications from NVE
NVE’s Map Services NVE Atlas, seNorge.no, Vann-Nett and Skrednett provide access to technical data related to NVE's area of responsibility.
Thematic geodata from NVE are available on the WMS format (Web Map Service). The list of WMS is available here, or at the National Map Portal www.geoNorge.no established by Norge digital/ Norway Digital.
Map Applications
NVE Atlas http://atlas.nve.no
NVE Atlas is NVE’s main Map Tool on the web which displays NVE’s thematic geodata. Examples of such geodata are catchments/watersheds, river network systems, annual runoff, flood inundation zones, levies/embankments, hydropower plants with reservoirs, hydrological monitoring stations etc., as well as links to 600 bathymetric maps of Norwegian lakes.
Special versions of NVE Atlas:
NVE Atlas – Vannkraftverk (Hydropower plants)
Map application which presents hydropower plants, displays licensing status of the plants, i.e. given, applied, rejected. This map service also provides access to documents for building hydropower plants as well as projects with granted licences.
NVE Atlas – Everk
Map application which presents concessionary areas including the responsible grid/energy company.
NVE Atlas - Potensialet for små kraftverk
Map application which presents the theoretical potential for small power plants.
NVE Atlas – Svekket is på regulerte vann
Map application which presents weak ice on lakes/reservoirs, due to hydropower production.
seNorge.no
Map application with daily updated maps for snow, weather, water and climate. Data are given for different time resolutions (daily, monthly and annually), as well as for climatic scenarios. seNorge.no gives access to maps from 1957 until today, plus a two day forecast. Time series are available for stations run by NVE and met.no. seNorge.no is operated by NVE in collaboration with met.no and the Norwegian Mapping Authority.
Vann-Nett statistikk/Water Net Statistics www.vann-nett.no
Map application which presents the environmental status of rivers, lakes and coastal waters in addition to the chemical status of groundwater. In Water Net Statistics you can find statistics for all administrative levels, from national to municipality level. Also contains featured images from many water bodies and anyone can add photos added to "their" water bodies*.
Vann-Nett saksbehandler/Water Net Manager
Map application developed for the Norwegian government's implementation of the Water Regulations Act (European Union's Water Framework Directive). Stakeholders may look into the background data and find the environmental status of a water body*. Data describing the environment surrounding the rivers, lakes and coastal waters are stored in a database via the Water Net Manager. Data on groundwater is also available in the application. Water Net is run by NVE, in co-operation with DN (the Norwegian Directorate for Nature Management) and Klif (the Climate and Pollution Agency).Lytt tilLes fonetisk
* “Water bodies” is the Water Framework Directive’s generic term for waters defined according to the Water Regulations Act (the EU's Water Framework Directive).
Skrednett (Avalanche Net) www.skrednett.no
Map application which presents data and information from the national landslide database established at NGU (the Geological Survey of Norway). Data about all types of landslides in Norway is displayed, including landslide hazard areas and registered events; approx. 32 500 records. In March 2009 the responsibility for Skrednett was transferred from NGU to NVE.
