1 New in Edition 12: ECDIS Symbols and Other ECDIS Information ECDIS

Symbology for displaying Electronic Navigational Charts (ENCs) on an Electronic Chart Display and Information System (ECDIS) has been added to U.S. Chart No. 1. See the Preface and Introduction sections for more details. 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 in the top left corner of this page. The ECDIS pages are also listed in the table of 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 other conditions, such as a ship’s draft. 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. Dangers that are shoaler are portrayed with the unique ECDIS “isolated danger” symbol shown 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\QRWHG7KHVHLQFOXGHEXWDUHQRW 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.

No man is an island and no single reference document stands on its own. 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. We want to know what you think works well, which parts are a little rocky, and what additional information you would like to have included in the next edition of U.S. Chart No. 1.

Sample Chart Layouts Section A presents two schematics showing typical layouts of the major elements of NOAA and NGA charts.

INFORMATION ON SELECTED CHART FEATURES Soundings The sounding datum reference is stated in the chart title. Soundings on NOAA and NGA 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 title and 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 a cursor inquiry. Heights 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 bare rocks are offset into the adjacent water, they are shown in parentheses. For ECDIS, the unit of height is meters. Drying Heights For rocks and banks that cover and uncover, elevations are underlined and are ref- erenced 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. 5 Shoreline Light Range (Visibility) Shoreline shown on charts represents the line of contact between the land and a A light’s range or visibility is given in nautical miles, except on the Great Lakes and VHOHFWHGZDWHUHOHYDWLRQ,QDUHDVDIIHFWHGE\WLGDOÀXFWXDWLRQWKLVOLQHRIFRQWDFWLV adjacent waterways, where light ranges are given in statute miles.

The dash can appear in any of the three positions. A structure or a conspicuous feature on a structure may be shown by a landmark symbol with a descriptive label (see Section E). Prominent buildings that could assist the Aids to Navigation Positioning mariner may be shown by actual shape as viewed from above (see Sections D and E). 7KH¿[HGDQGÀRDWLQJDLGVWRQDYLJDWLRQGHSLFWHGRQFKDUWVKDYHYDU\LQJGHJUHHVRI On NGA charts, landmark legends shown in capital letters indicate that a landmark is reliability.

8 Day, Dusk and Night Color Palettes ECDIS

ECDIS allows the mariner to change the color palette that is used to display an ENC. Three different color tables have been designed to provide the maximum clarity and contrast between features on the display under three different lighting conditions on the bridge, namely Day, Dusk and Night.

Each symbol is rendered in a different color appropriate for the lighting condition that the color table is meant for. This design provides maximum contrast for the display on a sunny day, as well as preserving night vision on a dimly lit bridge in the evening. This allows the mariner to look back and forth between the chart on the ECDIS display and out to sea through the bridge window without the mariner’s eyes needing to readjust to a difference in light intensity.

44 ECDIS Portrayal of Depths ECDIS

ECDIS depth related symbols closely resemble their paper chart counterparts; however, ECDIS provides valuable additional information to mariners that paper charts cannot.

Soundings ECDIS enables mariners to set their own-ship “safety depth.” If no depth is set, ECDIS sets the value to 30m. Soundings equal to or shoaler than the safety depth are shown in black; deeper soundings are displayed in a less conspicuous gray. Fractional values are shown with subscript numbers of the same size.

Depth Contours & Depth Areas Depth contours in ECDIS are portrayed with a thin gray line. Each pair of adjacent depth contours is used to create depth area features. These are used by ECDIS to tint different depth levels and to initiate alarms when a ship is headed into unsafe water. Portrayal of Depth Areas with 2 Color Settings Depth Contour Labels

ECDIS depth contour labels are not centered and oriented along iso- 6RPH(&',6HQDEOHPDULQHUVWRGH¿QHWZRDGGLWLRQDOGHSWKDUHDVIRUPHGLXP lines as they appear on paper charts. They are displayed upright and deep water and medium-shallow water by setting a “deep contour” value and may appear either on or next to the contour lines that they describe. a “shallow contour” value. If this option is used, the safety contour is displayed The labels are black and the same size as soundings, but the labels between the medium deep and medium shallow contours. have a light “halo” to set them apart. The graphic to the left shows depth labels and soundings both deeper and shoaler than the safety depth. Note that depths on NOAA paper charts and ENCs are usually com- piled in fathoms and feet. Because ECDIS displays depths in meters, soundings and contour lines often show fractional meter values. The “own-ship safety contour” (described below) is always displayed, but mariners may choose to have all other depth contours turned off.

Safety Contour ECDIS uses a “safety contour” value to show an extra thick line for the depth contour that separates “safe water” from shoaler areas. If the mariner does not set an own-ship safety contour value, ECDIS sets the value to 30m. If the ENC being displayed does not have a contour line equal to the safety contour depth value set by the mariner, then ECDIS sets the next deeper contour as the safety contour. Depending on the contour intervals used on individual ENCs, ECDIS may set different safety contours as a ship transits from one ENC to another. ECDIS will initiate an alarm if the ship’s future track will cross the safety contour Portrayal of Depth Areas with 4 Color Setting ZLWKLQDVSHFL¿HGWLPHVHWE\WKHPDULQHU

Two or Four Tints for Shading Depth Areas

ECDIS tints all depth areas beyond the (green tinted) foreshore in either one of two or Some ECDIS also provide the mariner with the option of one of four shades of blue. This is similar to the convention used for paper charts, but displaying a cross-hatch “shallow water” pattern over all the depths used to change from one tint to another are based on the safety contour and depth areas shoaler than the safety contour. thus “customized” for each ship. If the mariner chooses two shades to be displayed, water deeper than the safety contour is shown in an off-white color, water shoaler than the safety contour is tinted blue.

IALA Maritime Buoyage System

IALA International Association of Marine Aids to Navigation and Lighthouse Authorities

Where in force, the IALA System applies to all fixed and floating marks except landfall lights, leading lights and marks, sectored lights and major floating lights. The standard buoy shapes are cylindrical (can) , conical , spherical , pillar , and spar , but variations may occur, for example: light floats . In the illustrations in Q 130.1, only the standard buoy shapes are used. In the case of fixed beacons (lit or unlit), only the shape of the topmark is of navigational significance. Lateral marks are generally for well-defined channels.

130 There are two international buoyage regions where lateral marks differ. Region A is primarily comprised of the waters surrounding Greenland, Africa, Europe, Australia and Asia (except for Japan, the Republic of Korea and the Philippines). Region B is primarily comprised of the waters surrounding North and South America, Japan, the Republic of Korea and the Philippines.

ECDIS marks the boundary between IALA regions A and B with this symbol:
