ECDIS Symbols and Other ECDIS InformationSymbology 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 featureattribute 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, verticalclearance 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.7KHUH DUH PDQ\ RWKHU DWWULEXWH YDOXHV WKDW XVHUV PD\ REWDLQ WKURXJK D FXUVRU SLFN WKDW DUH QRW VSHFL¿FDOO\ QRWHG 7KHVH LQFOXGH EXW DUH QRW OLPLWHG WR WKHpurpose, 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.

INTRODUCTIONU.S. Chart No. 1 and Typical Chart LayoutsTwo Symbology Types Comprising Four Symbology SetsA brief description of the columns on each symbol description page is provided here.A detailed schematic layout of U.S. Chart No. 1 is on page 8. Section A, on pages 10and 11 presents schematics showing typical layouts of the major elements of NOAAand NGA charts.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:3DSHU &KDUW 6\PEROVINT — 7KH LQWHUQDWLRQDO RU ³,17 V\PEROV VSHFL¿HG LQ WKH RegulationsIRU ,QWHUQDWLRQDO ,17 &KDUWV DQG &KDUW 6SHFL¿FDWLRQV RI WKH , 2(International Hydrographic Organization).

INFORMATION ON SELECTED CHART FEATURESIALA Buoyage SystemSoundingsThe International Association of Marine Aids to Navigation and Lighthouse Authorities(IALA) Maritime Buoyage System is followed by most of the world’s maritime nations;however, systems used in some foreign waters may be different. IALA buoyage isdivided into two regions: Region A and Region B. All navigable waters of the UnitedStates follow IALA Region B rules, except U.S. possessions west of the InternationalDate Line and south of 10 north latitude, which follow IALA Region A rules.The sounding datum reference is stated in the chart title. Soundings on NOAA andNGA charts may be shown in fathoms, feet, fathoms and feet, fathoms and fractions,or meters and decimeters. In all cases the unit of depth used is shown in the chart titleand outside the border of the chart in bold type (see item b in Section A). For ECDIS,the sounding datum is part of the ENC metadata, which can be retrieved through acursor inquiry.Heights of lights, landmarks, structures, etc. refer to the shoreline plane of reference.The unit of height is shown in the chart title. When the elevations of islets or barerocks are offset into the adjacent water, they are shown in parentheses. For ECDIS,the unit of height is meters.The major difference between the two buoyage regions is the color of the lateralmarks. Region A uses red to port and Region B uses red to starboard (red-rightreturning). The shapes of the lateral marks are the same in both regions, can to portand cone (nun) to starboard, when entering from seaward. Cardinal and other marks,such as those for isolated dangers, safe water and special marks are also the samein both regions. Section Q and Appendix 1 illustrate the IALA buoyage system forboth Regions A and B.Drying HeightsU.S. Lateral MarksFor rocks and banks that cover and uncover, elevations are underlined and arereferenced to the sounding datum as stated in the chart title (or in the ENC metadata).When the heights of rocks that cover and uncover are offset into the adjacent water,they are shown in parentheses.Most of U.S. waters are in IALA Region B. In the U.S. system, on entering a channelfrom seaward, buoys and beacon dayboards on the starboard side are red with evennumbers and have red lights, if lit. Buoys and beacon dayboards on the port side aregreen with odd numbers and have green lights, if lit. Preferred channel buoys havered and green horizontal bands with the top band color indicating the preferred sideof passage.HeightsShorelineShoreline shown on charts represents the line of contact between the land and aVHOHFWHG ZDWHU HOHYDWLRQ ,Q DUHDV DIIHFWHG E\ WLGDO ÀXFWXDWLRQ WKLV OLQH RI FRQWDFW LV XVXDOO\ WKH PHDQ KLJK ZDWHU OLQH ,Q FRQ¿QHG FRDVWDO ZDWHUV RI GLPLQLVKHG WLGDO LQÀXHQFH D PHDQ ZDWHU OHYHO PD\ EH XVHG 7KH VKRUHOLQH RI LQWHULRU ZDWHUV ULYHUV ODNHV LV XVXDOO\ D OLQH UHSUHVHQWLQJ D VSHFL¿HG HOHYDWLRQ DERYH D VHOHFWHG GDWXP Shoreline is symbolized by a heavy line (symbol C 1).

Prominent buildings that could assistthe mariner may be shown by actual shape as viewed from above (see Sections Dand E).On NGA charts, landmark legends shown in capital letters indicate that a landmarkis conspicuous; the landmark may also be labeled “CONSPICUOUS” or “CONSPIC.”On NOAA charts, all landmarks are considered to be conspicuous, and landmarklegends shown in all capital letters indicate a landmark has been positionedaccurately; legends using both upper and lower case letters indicate an approximateposition.ECDIS portrays conspicuous features with black symbols and non-conspicuousfeatures with brown symbols. Only the conspicuous version is shown in the letteredsections of U.S. Chart No. 1. See the ECDIS “Conspicuous and Non-ConspicuousFeatures” page in front of Section E for more information.6Light Range (Visibility)A light’s range or visibility is given in nautical miles, except on the Great Lakes andadjacent waterways, where light ranges are given in statute miles. For lights havingmore than one color, NOAA charts give only the shortest range of all the colors.On NGA charts, multiple ranges may be shown using the following convention.

For example, Fl WG 12/8Mmeans the range of the white light is 12 nautical miles and the range of green lightis 8 nautical miles. For lights with three colors, only the longest and shortest rangesare given and the middle range is indicated by a dash. For example, Fl WRG 12-8Mmeans that the range of the white light is 12 nautical miles, the range of green light is8 nautical miles and the range of the red light is between 8 to 12 nautical miles.
