Map layer: Coast and fishing
Coast and fishing brings together three layers that show sea and lake depths as well as aquaculture licences in Norway. The category is useful when assessing coastal properties, cabin projects by water and when mapping marine use interests that can affect planning processes. The data comes mainly from Kartverket and NVE.

Layers in this category (5)
| Layer | Description | Source |
|---|---|---|
| Agriculture and fisheries buildings | Shows all building types that can be linked to agriculture and fisheries from Matrikkelen. | Kartverket |
| Shoreline management zone | National planning guidelines for differentiated management of the shoreline zone along the sea (GeoNorge.no). | Kartverket |
| Aquaculture register | Overview of aquaculture licences and decisions. | Fiskeridirektoratet |
| Sea depth (bathymetry) | Coastline contour, constructed coast and skerries referenced to mean high water. Basis for Kartverket's nautical charts. | Kartverket |
| Lake depth (bathymetry) | The lake database with hydrological information about Norwegian lakes. | Norges vassdrags- og energidirektorat (NVE). Datasets: Lake depth (bathymetry) |
Sea depth (bathymetry)
Coastline contour, constructed coast and skerries referenced to mean high water. The data forms the basis for Kartverket's official nautical charts and gives a visual picture of the coastline and depth-related constraints on development close to the sea. Useful for assessing access to a quay and mooring, shoreline zone clarifications and whether a property is affected by maritime legal rights.

About the map layer
Coastline contour referenced to mean high water; depth points and contours following the Norwegian Armed Forces' navigation plan (for example 2, 5, 10 … 100, 150, 200 m). Basis for nautical products and coastal zone plans.

Sublayers (16)
| Sublayers | Description |
|---|---|
| Constructed coastline contour | Derived or adjusted coastline contour. |
| Coastline contour | Mapped coastline. |
| Depth point | Measured or mapped depth point. |
| Skerry | Rock or reef lying at the water surface or just above the water. |
| Dredged depth detail | Depth details in dredged areas. |
| Dry dock | Facility for maintaining vessels on land. |
| Dry dock boundary | Boundary of a dry dock. |
| Floating dock | Floating structure used for docking vessels. |
| Floating dock boundary | Boundary of a floating dock. |
| Shoal | Shallow area that is dangerous for navigation. |
| Dredged area | Area where the seabed has been dredged. |
| Dredged area boundary | Boundary of a dredged area. |
| Drying area | Area that dries out at low tide. |
| Drying area boundary | Boundary of a tidal drying area. |
| Depth contour | Contour lines connecting equal depths. |
| Depth layer | Classified depth intervals shown as areas. |
Lake depth (bathymetry)
The lake database of Norges vassdrags- og energidirektorat (NVE) with hydrological information about Norwegian lakes: area, volume, maximum and average depth. Relevant for cabin projects by water and for assessing intervention requirements under the Water Resources Act (vannressursloven).

About the map layer
NVE's lake database (≥ 2,500 m²) with bathymetric contours where such data is available. Measurement method and accuracy vary.
Update frequency: Real time.
Aquaculture register
Overview of aquaculture licences and decisions registered with Fiskeridirektoratet. Shows where licences have been granted for fish farms at sea. Relevant for mapping use interests that can set conditions for land use planning along the coast. The layer is also available under Water. Datasets: Aquaculture register.

About the map layer
Licences and decisions for aquaculture sites, including location, species, capacity, biomass, escapes and environmental surveys.
Update frequency: Monthly.
Tips
- For storm surge and sea level rise exposure along the coast, use High water / storm surge in Risk.
- Shoreline zone rules (the 100-metre belt) are shown in the Shoreline management zone map layer under Nature.
