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.


  • 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.

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