National Ocean Service, NOAA (N/CS2) Attention: U.S. 1 may be submitted through ASSIST, the NOAA Coast Survey stakeholder engagement and feedback website at: or mailed to: Please let NOAA know what additional information you would like to see in the next edition.Ĭorrections, comments, or questions regarding U.S. The ECDIS user and developer communities are invited to help improve the presentation of ECDIS symbology and information in U.S. 1 is a handy guide for ECDIS users, but it is no substitute for mandated ECDIS training. These include, but are not limited to, the 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 AIS transmitted signals information regarding pilotage services and many more. There are many other attribute values that users may obtain through a cursor pick that are not specifically noted. The cursor pick icon, shown at left, is used to indicate when a reference to a cursor pick is made. This is especially true if a particular value, such as height, vertical clearance or the like is included in the INT symbol description. (See the ECDIS Portrayal of Depths page for more information about the ECDIS safety contour.)Īnother 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. Dangers that are shoaler are portrayed with the unique ECDIS “isolated danger” symbol shown at left. An important example is that ECDIS displays wrecks, rocks and other obstructions with their traditional “paper chart” symbols if they are at or deeper than the depth of the safety contour set for the ship. 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 other conditions, such as a ship’s draft. The ECDIS pages are also listed in the table of contents in italic type. These pages are distinguished by the ECDIS icon, as shown in the top left corner of this page. 1, there are now several special pages devoted exclusively to providing important details about ECDIS. In addition to the ECDIS symbols shown in the traditional lettered sections of U.S. Symbology for displaying Electronic Navigational Charts (ENCs) on Electronic Chart Display and Information Systems (ECDIS) has been added to U.S.
