Various and diverse methods exist for the correction of electronic navigational charts.

Nautical charting may take the form of charts printed on paper or computerised electronic navigational charts.

S-63 standard for encrypting, securing and compressing electronic navigational chart (ENC) data.

Over 400 paper charts are produced by the AHS, with conversion of these to electronic navigational chart format due to be completed in 2011.

The Hydrographic Service has the operational responsibility for the international electronic navigational chart centre Primar, based in Stavanger.

A Chartplotter is a device used in marine navigation that integrates GPS data with an electronic navigational chart (ENC).

An electronic navigational chart is an official database created by a national hydrographic office for use with an Electronic Chart Display and Information System (ECDIS).

RSS Endurance became the first ship in the world to use official electronic navigational charts with the Electronic Chart Display and Information System (ECDIS) to circumnavigate the world.

During 2008, Tridentnav Systems was registered as an OEM (Original Equipment Manufacturer) within the IHO S-63 Data Protection Scheme, a system for handling encrypted Electronic navigational charts.

Electronic navigational charts, which use computer software and electronic databases to provide navigation information, can augment or in some cases replace paper charts, though many mariners carry paper charts as a backup in case the electronic charting system fails.

The IHO publishes the international standards related to charting and hydrography, including S-57 IHO Transfer Standard for Digital Hydrographic Data, the encoding standard that is used primarily for electronic navigational charts.

Over the years, following the evolution of real systems installed on board, naval simulators have become rich, complex systems with many components such as ECDIS electronic navigational charts, AIS navigation radio helpers, and GMDSS communications systems.

Of note is its system of inland electronic navigational charts for real-time display of vessel positions relative to waterway features and its system of map overlays that provides targeted, detailed information about inland waterways to the dredging industry, environmental planners, hydraulic engineers and others.

An ECDIS system displays the information from electronic navigational charts (ENC) or Digital Nautical Charts (DNC) and integrates position information from position, heading and speed through water reference systems and optionally other navigational sensors.
