ENC overlap

According to international standards, ENCs should not overlap within the same navigational usage band. The ENC overlap checker displays a graphical overview of ENCs overlapping based on the selection criteria chosen.

This tool allows ENCs from one country in the database to be chosen, and will then display a list of overlapping ENC cells if an overlap for the chosen country exists.

We will always perform an overlap check against our database on any new ENC cells uploaded to our service. Should any overlap be discovered, a report will be produced and sent to the relevant HO.
