When using this standard, symbols can also be added according to the characteristics of different regions and the end of the chart, and legends can be added at designated locations outside the gallery.
2Definitions
This standard adopts the following definitions,
2. 1 Depth datum sounding 1. The depth of water indicated on the nautical chart is the depth of the sea. In coastal areas of China, the "theoretical lowest tide level" is generally used as the depth datum. 2.2 Vertical datum Vertical datum Vertical datum The starting point for the elevation of ground points. In coastal areas of China, the "1985 National Height Datum" is generally used as the elevation datum. 2.3 Sounding sounding The vertical distance from the depth datum to the bottom of the water. 2.4 Drying height Drying height The height above the depth datum. 2.5 Light height The height from the center of the light source of the clevatirn tf lighul light. In coastal areas of China, the average high tide level is generally used as the starting point. 2.6 Light range Tangeaf light
The range of China's coastal navigation lights is the distance (nautical miles) that the navigation lights can be seen by the sailor at a height of 5m above the sea under clear sky and dark night conditions.
2.7 Vertical clearance
The vertical clearance of the bridge is the vertical distance from the high water level of the river (the highest design extension water level) to the lowest point of the clearance width under the bridge. The clearance of overhead pipelines, wires, etc. is the vertical distance from the high water level of the river or the average tide to the lowest point of the pipeline.
2.Bearing elevation
The height of the whole from the base of the landform and landform. 2.9 Bearing
The bearing shown on the nautical chart is the true bearing of the day mark when the observer observes it at sea. 3 Requirements
31 Navigation charts are printed in black, yellow (brown), purple and light blue. Approved by the State Administration of Quality Supervision, Inspection and Quarantine on December 15, 1998. Implementation on May 1, 1999. GB 12319-199B
3.2 Contour lines and other landform elements may be printed in brown when black is not suitable. The land is not dyed with any color. 3.3 When there are many boundary lines on the map, the boundary lines of the sea-sweeping survey area may be printed in green and overprinted with dots to make the map clear. 3.4 All the separations of the color-separated channels are overprinted with 100 lines of dots. 3.5 Independent landform symbols are generally drawn perpendicular to the south corridor, except for some that are expressed in true direction. 3.6 The size and form of the configuration symbols on the map should basically be as shown in the diagram. The symbol interval can be slightly enlarged when the area is large. 3.7 Chart symbols are generally indicated in the size specified in this standard. If only one size is noted next to a symbol, it indicates the diameter of a circle or circumscribed circle, the side length of an equilateral triangle or a square; if two sizes are listed in parallel, the first number indicates the height of the main part of the symbol, and the second number indicates the width of the main part of the symbol: the number at one end of a linear symbol, a single line refers to its thickness. Two parallel lines refer to the width of the line (a street refers to the width of the blank part); the number between two measuring point symbols refers to the gap between the two points. The size that needs to be specially marked on the symbol is indicated by a line. 3.8 Where the property symbols are added to the regional boundary symbols on the boundary line (such as: the boundary of the staggered area, the boundary of the prohibited anchor and fishing area, etc.), the property symbols on the regional boundary are generally spaced 50~80mm apart. 3.9 The size of various symbols is specified according to the map sheet with medium density of nautical chart content. The spacing between symbols on the nautical chart should not be less than 0.2mm, except for those that allow symbols to be crossed and combined. In the case of densely packed symbols and close distances, the symbol size can be reduced. 3.10 If the thickness of the symbol line, the length of the line segment and the angle of the intersecting line segment are not specified, this standard shall prevail when drawing. Generally speaking, the line thickness is 0,1mu and the point size is 0.2.

Brief description
5.5.2 Azimuth circle Compass circle> is used to measure the azimuth on the map. The annotation on the azimuth circle indicates the true azimuth. The magnetic variation and the estimated year are centered on the left side of the center line. The annual difference is centered on the right side of the center line. W indicates that the magnetic variation (annual difference) is biased to the west, and E indicates that the magnetic variation (annual difference) is biased to the east. When the scope of the sub-maps and attached figures is small, the azimuth circle is not configured, and the magnetic variation and annual difference are noted in the title bar. If the map has no navigation or anchoring significance, the magnetic variation and annual difference can be noted.
5. 5.3 Iso-magnetic deviation lines are lines connecting points with equal magnetic variation. The magnetic variation (in whole degrees or degrees and minutes) should be noted on the iso-magnetic deviation lines. E and W indicate that the magnetic variation is biased to the east and west respectively.
5.5.4 Local magnetic anomaly zone refers to the area where the geomagnetic elements are significantly different from the normal values of the surrounding areas. It is mainly caused by the magnetic distribution of rocks or minerals in the shallow layer of the crust and the uneven distribution of electromagnetic properties and terrain in the deeper layer. The left figure shows the difference between the normal magnetic deviation and the normal value (the abnormal magnetic deviation value can also be noted), and the middle figure is not in proportion. The value in the figure is the abnormal magnetic deviation value. The right figure shows the unknown degree and range of magnetic anomaly. Natural features

6.1 Coast
GB12319--1998
Brief description
6.1.1 The coastline refers to the trace line of the boundary between land and water at the average high tide. It can generally be determined based on the local sea erosion terraces, beach deposits or seashore plants. The coastline of rivers and lakes that have been measured by water depth should be represented by this symbol. The boundary between land and water at low tide is the low coastline. When the low coastline (0.1mm solid line) is shown on the map, the high and low coastlines are colored (regardless of whether the high coastline is in the map). When there is only the low coastline, the part above the low coastline is colored according to the ground. 6.1.2 The coastline that has not been measured or the measurement accuracy does not meet the requirements of the measurement specification. This symbol can be combined with other symbols of coast properties to represent sketched gravel shores, rocky shores, etc. 6.1.3 Steep bank refers to the area with steep bank slope (slope above 50°). This symbol is used to indicate the area with seven or unknown properties. 10 is the ratio. When the horizontal projection width of the bank is less than 0.6 mm on the map, it is drawn with a short line of 0.6 mm; when it is 0.6 mm to 1.0 mm, it is represented by a short line according to the actual width; when it is greater than 1.1 mm, it is represented by a long and short line according to the scale. 6.1.4 Rocky bank is represented by this symbol, and 25 is the relative height. 6.1.5 Bank composed of coarse and fine sand.
6.1.6 Bank composed of gravel and pebbles. When there is no obvious coastline, it is represented by the right figure. 6.1.7 Bank composed of stones of different sizes. When there is no obvious coastline, it is represented by the right figure. Isolated stones along the coast can also be represented by referring to the symbols on the map.
6.1.8 The shore made of rocks and trees,
6.1.9 The shore with a certain slope along the coastal construction should be indicated by this symbol. The left picture shows stone and concrete structures, and the right picture shows regular material structures such as masonry. When the width is greater than 1mm on the map, it should be indicated in proportion; when it is 0.6mm to 1mm, it should be expanded to 1mm for indication, and when it is narrower than 0.6mm, it is generally not indicated.
6.1.10 The shore is a landform with irregular height, width and slope. It is indicated only when it is 5mm long and 1.5m or higher in height. When the width (between the slope foot) is 1mm or more on the map, it is indicated by a double row of short lines: when the width is less than 1mm on the map, it is indicated by a single row of short lines. 6.1.11 The shore with trees (mangroves) growing along the coast is indicated by this symbol. When there is no obvious coastline, it is indicated by the right picture. This symbol can be combined with sandy shores, etc. 6.1.12 The shore with no sound along the coast. When there is no obvious coastline, use the right picture. This symbol can be combined with sandy coast, etc. 6.1.13 Banks with weeds. When the coastline is particularly obvious, use the right picture. This symbol can be combined with banknote coast, etc. 13
