NVDB TN-ITS Export API

This service provides standardized exports of Norwegian road network data from NVDB (Nasjonal vegdatabank) in TN-ITS format for European data exchange.

Access complete snapshots and incremental daily updates through our REST API, explore available datasets in the browser, or verify data quality with the interactive map viewer.

⚠️ Note: Datasets may include roads that are not yet open for traffic. These roads are part of the road network database but may still be under construction or pending official opening.
