There are currently two methods of carrying out electronic chart corrections, either via Weekly Updates, CD or downloaded weekly from a recognized electric chart supplier's data. The preferred method will be decided by the Management Office, depending on the communications equipment onboard the vessel.

To correct a chart, look up the number of the chart in the index at the front of the NTM, by the chart number there will be a list of all the corrections that relate to that chart. Each correction is given a number to identify it. You then need to look up the correction to discover the details.

Correcting and upgrading a navigation chart is a constant process. Once a chart is published, constantly changing navigational features and aids or other relevant information have to be promulgated in order to update the ships navigating in those areas.

Permits are used to control the permission to use a chart. They prevent unofficial copying and distribution.

ENCs are updated by weekly 'Notices to Mariners' issued by Hydrographic Offices / Regional ENC co-ordination centers ( RENC) and corrections are received on the vessel either by email or data file (AVCS DVD). The actual updating is either applied to the ECDIS chart database automatically or by the user.

When a new chart or new edition of a chart is received on board this procedure must be followed: Highlight the chart number in the correction log. ... Enter the Chart Folio and sequence number, from the index. ... Correct the chart for any pending corrections. ... Correct the Admiralty Chart Catalogue (NP 131) if affected.

The sensors providing the data inputs to ECDIS are the following: The global positioning system (GPS and/or DGPS). The automatic identification system (AIS). The radar and automatic radar plotting aid (ARPA).
