New in Edition 12: ECDIS Symbols and Other ECDIS Information
Symbology for displaying Electronic Navigational Charts (ENC's) on an Electronic Chart Display and Information System (ECDIS) has been added to U.S. Chart No. 1.
In addition to the ECDIS symbols shown in the traditional lettered sections of U.S. Chart No. 1, there are now several special pages devoted exclusively to providing important details about ECDIS. These pages are distinguished by the ECDIS icon, as shown below. The ECDIS pages are also listed in the table of contents in italic type.
