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 infor mation 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.

PREFACE

INTRODUCTION

Presentation of Two Symbology Sets

New Column Headers

This edition of U.S. Chart No. 1 has a new name and a new look. Its title is now SymEROV$EEUHYLDWLRQVDQG7HUPVXVHGRQ3DSHUDQG(OHFWURQLF1DYLJDWLRQDO&KDUWV. For WKH¿UVWWLPH86&KDUW1RSUHVHQWVERWKRIWKHPDMRUV\PERORJ\VHWVXVHGIRU marine navigation.

The orientation of this edition of U.S. Chart No. 1 has been rotated 90° into a land scape format to allow two additional columns to be added to the right side of the page. These columns hold the ECDIS symbols corresponding to the paper chart symbols shown on the left side.

As in previous editions, the symbols used on paper nautical charts produced by the National Oceanic and Atmospheric Administration (NOAA) and the National GeospatialIntelligence Agency (NGA) and digital raster representations of those charts, such as NOAA Raster Nautical Charts (NOAA RNCs®), are presented in lettered sections organized in categories, such as Landmarks, Depths, and Lights. New in this edition is the inclusion of the corresponding symbols used to portray Electronic Navigational Chart (ENC) data on Electronic Chart Display and Information Systems (ECDIS) as VSHFL¿HGE\WKH,QWHUQDWLRQDO+\GURJUDSKLF2UJDQL]DWLRQ,+2

Any variations from INT 1 symbology that are used on charts produced by NOAA or NGA are shown in the NOAA, NGA and the “Other NGA” columns (columns 4a, 4b, and 5 respectively).

U.S. Chart No. 1 RQO\VKRZVWKHV\PERORJ\XVHGRQ ECDIS.

ECDIS symbols and their descriptions are shown in columns 6 and 7 respectively. The ECDIS description usually provides the generic symbol name given in the IHO 6SHFL¿FDWLRQVIRU&KDUW&RQWHQWDQG'LVSOD\$VSHFWVRI(&',6 although sometimes other clarifying terms are also provided in column 7. The ECDIS symbols shown use the day color palette (see page 9). When columns 4a and 4b are combined, this indicates that NOAA and NGA both use the same non-INT 1 symbol for that particular feature. When any of columns 4a, 4b, or 5 are blank, then the INT 1 symbol has been adopted for use by the organization for which that column applies. The schematic layout following this introduction shows a typical symbol table page. It provides details about the table headers and the types of information presented in each of the columns. 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.

Shoreline

Light Range (Visibility)

Shoreline shown on charts represents the line of contact between the land and a VHOHFWHGZDWHUHOHYDWLRQ,QDUHDVDIIHFWHGE\WLGDOÀXFWXDWLRQWKLVOLQHRIFRQWDFWLV XVXDOO\WKHPHDQKLJKZDWHUOLQH,QFRQ¿QHGFRDVWDOZDWHUVRIGLPLQLVKHGWLGDOLQÀX ence, a mean water level may be used. The shoreline of interior waters (rivers, lakes) LVXVXDOO\DOLQHUHSUHVHQWLQJDVSHFL¿HGHOHYDWLRQDERYHDVHOHFWHGGDWXP6KRUHOLQH is symbolized by a heavy line (symbol C 1). Apparent shoreline is used on charts to show the outer edge of marine vegetation where the limit would be expected to appear as the shoreline to the mariner or where it prevents the shoreline from being clearly GH¿QHG$SSDUHQWVKRUHOLQHLVV\PEROL]HGE\DOLJKWOLQHV\PEROV&&&S C q and C r).

A light’s range or visibility is given in nautical miles, except on the Great Lakes and adjacent waterways, where light ranges are given in statute miles. For lights having more 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 lights ZLWKWZRFRORUVWKH¿UVWQXPEHULQGLFDWHVWKHUDQJHRIWKH¿UVWFRORUDQGWKHVHFRQG number indicates the range of the second color. For example, Fl WG 12/8M means the range of the white light is 12 nautical miles and the range of green light is 8 nautical miles. For lights with three colors, only the longest and shortest ranges are given and the middle range is indicated by a dash. For example, Fl WRG 12-8M means that the range of the white light is 12 nautical miles, the range of green light is 8 nautical miles and the range of the red light is between 8 to 12 nautical miles. The dash can appear in any of the three positions.

Landmarks A structure or a conspicuous feature on a structure may be shown by a landmark sym bol with a descriptive label (see Section E). Prominent buildings that could assist the mariner may be shown by actual shape as viewed from above (see Sections D and E). On NGA charts, landmark legends shown in capital letters indicate that a landmark is conspicuous; the landmark may also be labeled “CONSPICUOUS” or “CONSPIC.” On NOAA charts, all landmarks are considered to be conspicuous, and landmark leg ends shown in all capital letters indicate a landmark has been positioned accurately; legends using both upper and lower case letters indicate an approximate position. ECDIS portrays conspicuous features with black symbols and non-conspicuous fea tures with brown symbols. Only the conspicuous version is shown in the lettered sec tions of U.S. Chart No. 1. See the ECDIS “Conspicuous and Non-Conspicuous Fea tures” page in front of Section E for more information. IALA Buoyage System The 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 is divided into two regions: Region A and Region B. All navigable waters of the United States follow IALA Region B rules, except U.S. possessions west of the International Date Line and south of 10° north latitude, which follow IALA Region A rules. The major difference between the two buoyage regions is the color of the lateral marks. Region A uses red to port and Region B uses red to starboard (red-right returning). The shapes of the lateral marks are the same in both regions, can to port and 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 same in both regions. Section Q and Appendix 1 illustrate the IALA buoyage system for both Regions A and B. U.S. Lateral Marks Most of U.S. waters are in IALA Region B. In the U.S. system, on entering a channel from seaward, buoys and beacon dayboards on the starboard side are red with even numbers and have red lights, if lit. Buoys and beacon dayboards on the port side are green with odd numbers and have green lights, if lit. Preferred channel buoys have red and green horizontal bands with the top band color indicating the preferred side of passage. 6

Floating aids are moored to sinkers by varying lengths of chain and may shift due to sea conditions and other causes. Buoys may also be carried away, capsized or sunk. Lighted buoys may be extinguished and sound signals may not function, because of ice or other causes.

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.

Conspicuous and Non-Conspicuous Features ECDIS

There are 25 features for which ECDIS displays either a black symbol, if the feature is visually conspicuous, or a brown symbol if is not. Only conspicuous landmarks are depicted on NOAA paper charts and ENCs. Therefore, only the conspicuous symbol versions are shown in the symbol tables of U.S. Chart No. 1. Both versions of the symbols for these features are shown on this page.

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. Depth Contour Labels ECDIS depth contour labels are not centered and oriented along iso lines as they appear on paper charts. They are displayed upright and may appear either on or next to the contour lines that they describe. The labels are black and the same size as soundings, but the labels 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.

Portrayal of Depth Areas with 2 Color Settings 6RPH(&',6HQDEOHPDULQHUVWRGH¿QHWZRDGGLWLRQDOGHSWKDUHDVIRUPHGLXP deep water and medium-shallow water by setting a “deep contour” value and a “shallow contour” value. If this option is used, the safety contour is displayed between the medium deep and medium shallow contours.

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 ZLWKLQDVSHFL¿HGWLPHVHWE\WKHPDULQHU

Portrayal of Depth Areas with 4 Color Setting

Two or Four Tints for Shading Depth Areas ECDIS tints all depth areas beyond the (green tinted) foreshore in either one of two or one of four shades of blue. This is similar to the convention used for paper charts, but the depths used to change from one tint to another are based on the safety contour and 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.

Some ECDIS also provide the mariner with the option of displaying a cross-hatch “shallow water” pattern over all depth areas shoaler than the safety contour.

Q

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:
