ECDIS Symbols and Other ECDIS Information

Symbology for displaying Electronic Navigational Charts (ENCs) on Electronic Chart Display and Information Systems (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 providingimportant details about ECDIS. These pages are distinguished by the ECDIS icon, as shown in the top left corner of this page. The ECDIS pages are also listed in the tableof contents in italic type.

One major difference in the use of paper charts and ENCs is the ability of ECDIS to display the same feature differently depending on user settings and otherconditions, such as a ship’s draft. An important example is that ECDIS displays wrecks, rocks and other obstructions with their traditional “paper chart” symbols ifthey are at or deeper than the depth of the safety contour set for the ship. Dangers that are shoaler are portrayed with the unique ECDIS “isolated danger” symbolshown at left. (See the ECDIS Portrayal of Depths page for more information about the ECDIS safety contour.)^ Another advantage that ECDIS provides over paper charts is enabling users to obtain more information about a feature through a “cursor pick.” Some feature attribute values that can be obtained by cursor pick are noted throughout U.S. Chart No. 1. This is especially true if a particular value, such as height, vertical clearance or the like is included in the INT symbol description. The cursor pick icon, shown at left, is used to indicate when a reference to a cursor pick is made. 7KHUHDUHPDQ\RWKHUDWWULEXWHYDOXHVWKDWXVHUVPD\REWDLQWKURXJKDFXUVRUSLFNWKDWDUHQRWVSHFL¿FDOO\QRWHG7KHVHLQFOXGHEXWDUHQRWOLPLWHGWRWKH purpose, seasonality, periodicity, status, color, height, type of structure and the visual or radar conspicuousness of features; shape, color or color pattern of buoys;characteristics of lights; category of obstructions and wrecks; radar wave length, radio frequency, communication channel and call signs; the presence of AIStransmitted signals; information regarding pilotage services and many more. U.S.^

Chart No. 1 is a handy guide for ECDIS users, but it is no substitute for mandated ECDIS training. The ECDIS user and developer communities are invited to help improve the presentation of ECDIS symbology and information in U.S. Chart No. 1. Please le

INTRODUCTIONTwo Symbology Types Comprising Four Symbology Sets^ U.S.

Chart No. 1 presents two types of symbology used for marine navigation – thesymbols used on paper nautical charts (and their digital raster image equivalents)and the corresponding symbols used to portray Electronic Navigational Chart (ENC)data on Electronic Chart Display and Information Systems (ECDIS). Within these two types, four separate symbology sets are shown. These are describedbelow: Paper Chart Sym
