Electronic navigational chart
open-in-new
<p>An electronic navigational chart (ENC) is an official database created by a <a href="/facts/List_of_Members_of_the_International_Hydrographic_Organization/PUdwaoPv">national hydrographic office</a> for use with an Electronic Chart Display and Information System (ECDIS). ECDIS and ENCs are the primary means of electronic navigation on <a href="/facts/Cargo_ships/G7JSpeMc">cargo ships</a>. Charts can be used in <a href="/facts/Navigation/sGGAJ0AQ">navigation</a> to provide an indication of location once a position is fixed and the charted depths can be used in <a href="/facts/Under_keel_clearance/Ag4G3MTa">under keel clearance</a> calculations to ensure the ship is navigating in safe water. </p><p><a href="/facts/Inland_Electronic_Chart_Display_and_Information_System/CvSmV8ro">Inland Electronic Chart Display and Information System</a> are similar systems used for navigation of inland water. </p>
