Map data for Norway

Behind each layer

Where each dataset comes from, and what that means for the model.

Terrain

The 1 m national model from the 2016–2022 lidar campaign: 230,000 km² at 2–5 points per m², published openly by Kartverket.

Buildings

OpenStreetMap footprints, which in Norway largely descend from Kartverket's building registers through the community's national import, so coverage is close to complete. Heights are measured against the national lidar surface, never read from mapped tags.

Roads

Centrelines from NVDB, the road database Statens vegvesen keeps for every drivable road; the open export refreshes weekly. Widths are modelled — the source is a centreline network, not surveyed edges.

Water

Lake outlines from NVE's national lake database; the sea is detected against the terrain model. Water bodies are delivered as level surfaces.

Site objects

Walls, fences and hedges from OpenStreetMap where mapped — density follows local mapping activity.

Parcels

Parcel geometry from Matrikkelen, the national cadastre. Point precision follows survey history — about 4 cm where recently surveyed, 13 cm for older classes, metre-class where boundaries were digitised from the 1:5,000 economic map series — and the register records which is which.

Surface image

A cartographic ground texture GeoAnvil renders from OpenStreetMap data. Norwegian orthophotos (Norge i bilder) sit under Geovekst licensing, so the texture is drawn, not photographic.

Contours

Generated from the same lidar model as the terrain surface, at the interval you choose — contours and terrain always agree because they are one model.

FKB Buildings

Roof geometry stereo-plotted by operators from the national aerial programme — Takkant, Mønelinje, Taksprang. The wall line (Fasadeliv) is optional in the specification. Licensed through Geovekst.
