What data is expected?

A geographical map of the country including national traffic routes, stretches of water, and markings of heights. The map must at least be provided at a scale of 1:250,000 (1 cm = 2.5km). Geographic information is instrumental for many use cases, including the mapping of unemployment statistics or demographics, as well as journey planning. See our methodology section for more information.

  • Scale of 1:250,000 (1 cm = 2.5km)
  • Markings of national traffic routes
  • Markings of relief/heights
  • Markings of water stretches
  • National borders

    The data is also available as a WMS service, which offers a beautiful national map at 1:250k for Norway to import in GIS clients []. The data is also available in an ESRI file geodatabase. This is ESRI native and proprietary format, but QGIS has support for it, so it complies with the survey requirements. PostGIS, a spatial extension for PostgreSQL object-relational database, supports GIS objects defined as a superset of the "Simple Features" defined by the OpenGIS Consortium. As of version 0.9, PostGIS supports all the objects and functions specified in the OGC "Simple Features for SQL" specification.
