ENC Improver has been designed to provide users with a simple system to give feedback on Norwegian ENCs. Everybody who has an ENC license for navigation will receive user access to ENC Improver through their supplier.

Feedback from the users are important contributions, which helps to ensure that the ENCs remain updated and that safety at sea is maintained.


  • On the map reporting (add a point on the chart and describe the problem)
  • Report positions (give the coordinates and describe the problem)
  • Give general feedback on ENCs
  • A monitoring system is in place to follow up received feedback.

To submit feedback, Internet access is required.

If you have feedback on functionalities in ENC Improver, please send an e-mail to kundesenter@kartverket.no.
