Base map refers to the basic map necessary for making sea area charts. The latest national basic geographic information map remote sensing images or sea charts that can reflect the adjacent sea areas and land elements (coastline, place names, isobaths, etc.) should be used. The base map of the Zonghai location map can be a digital line map, or a topographic map or sea chart in raster format, or a remote sensing image with a spatial resolution of not less than 10m.
The base map of the Zonghai boundary map and the base map of the Zonghai plan layout map should be a digital line map. 5.1.2 Base map elements
The base map of the Zonghai map should include the following basic geographic information: sea area, islands, land area, coastline, etc.: a

Sea area, land administrative boundaries·Projects involving international optical cables should include the outer boundary of the territorial sea: islands, bays, estuaries, straits, important place names and other notes. e
The mainland coastline adopts the latest coastline survey results announced by the province. For mainland coastlines that have not announced coastline survey results, the coastline of the provincial marine functional zoning shall prevail: the island coastline shall be based on actual measurements: the administrative boundaries shall adopt the approved land administrative boundaries and sea administrative boundaries. The base map of the Zonghai location map should be marked with isobaths or water depth points: the base map of the Zonghai boundary map and the base map of the Zonghai plane layout map may not mark isobaths and water depth points according to actual conditions3

Boundary Point Compilation
Boundary point compilation is based on boundary point coordinates and is compiled through a computer mapping system. The diagram is shown in Appendix A. HY/T251—2018
Boundary points are marked from the lower left corner of each sea unit in principle, and boundary points are uniformly numbered in Arabic numerals, starting from 1 and continuously numbered in a counterclockwise direction. The boundary points of different internal units of the sea area are numbered in the order of the secondary categories of HY/T123 sea area use. For sea use units with many boundary points and consecutive numbers, only the key boundary points can be marked in principle to clearly reflect the boundary of the sea area: for arc boundary areas, on the basis of the boundary points at both ends and the vertex of the arc, the number of boundary points should be appropriately increased to reflect the arc characteristics. The boundary point serial number marking generally uses 14K Song font bold and black. When the boundary points are dense, the boundary point number marking can be in the form of lead lines. The lead line width is 0.2mm and the color is RGB: 0.92.230. Boundary line drawing
Connect the boundary points of the internal units of the sea area in sequence in a counterclockwise direction to form a closed boundary line. For circular boundary areas, the coordinates of the center of the circle and the radius of the circle can be used to express the boundary range of the sea use unit. See Appendix A for the diagram. 5.3.2.3 Compilation of internal units of the Zonghai
The internal units of the Zonghai are compiled in the form of polygonal patches. The patch patterns compiled in different sea use methods are shown in Appendix A. 5.3.2.4 Adjacent Zonghai Information
The adjacent Zonghai information includes the adjacent Zonghai patches, project names and other information. The surrounding related information is generally marked in 14K Song font, black. The adjacent Zonghai patch pattern is shown in Appendix A. 5.3.2.5 Boundary Point Coordinate List
The Zonghai boundary map should list the boundary point coordinate list. The boundary point coordinate units are degrees, minutes and seconds, and 3 decimal places are retained after the second. The boundary point number corresponds to the number in the map and is listed in order. If there are many boundary points and the list space is insufficient, an additional page can be added to fill in the boundary point numbers and coordinates, and add the acceptance instructions. The names of the surveyor, draftsman and reviewer should be signed on the additional page, and the surveying and mapping unit should be indicated and stamped with the unit seal. The name of the boundary point list is "Boundary point number and coordinates (North Latitude East Longitude)". All fonts in the table are 11K Songti black, the line width of the table is unified to 0.1mm, the color is R, GB: 0.0.0. The diagram of the boundary point coordinate list is shown in Figure 1. L10mm

Figure 1 Illustration of the list of boundary point coordinates
The boundary map of the Zonghai should list the internal units of the Zonghai, including internal units, sea use methods, boundary lines and areas. The internal units are filled in according to the specific use of the units. The sea use method adopts the secondary sea use method in HY/T123. The boundary line is represented by the boundary point number plus ", and the first and last digits of the boundary point number are the same. For internal units with many boundary points, for the convenience of writing, the continuous numbering part can be omitted in the middle, such as: 1-2--79-80-1. The unit of area is public, and 4 decimal places are retained. All fonts in the table are 11K Songti black, the table line width is unified to 0.1mm, and the color is R, GB: 0, 0.0.

Cartographic Information List
For the requirements of compiling the cartographic information list, see 5.5.3.5.3.2.8
For the requirements of compiling the map name, scale, outline, latitude and longitude notes and compass map name, see 5.5.4.
The scale of the Zonghai Boundary Map should be able to clearly reflect the distribution of the boundary points and the scope of the boundary. For the requirements of compiling the scale style, see 5.5.5
For the requirements of drawing outline and longitude and latitude annotations, see 5.5.6. For the requirements of drawing compass, see 5.5.7.
Requirements for drawing sea map of typical sea use projects
For sea uses with complex plane layout or large span of occupied sea area such as offshore wind power, cross-sea bridges, submarine cables and pipelines, in order to clearly reflect the shape of the sea and the distribution of boundary points at the same time, the sea boundary map can be drawn by partial enlargement for typical, important and complex areas on the basis of reflecting the plane distribution of the sea as a whole. When partial enlargement is adopted, the annotation frame form is used, the line width is 0.2mm, the color is R, GB: 0.0.0: Place the scale in the lower right corner of the annotation frame. The annotation frame map and scale should be able to clearly reflect the shape of the sea and the distribution of boundary points.
For sea uses with large differences in length and width such as submarine cables and pipelines, cross-sea bridges, and roads, it is advisable to adopt a partial unequal proportion method to shift and draw according to actual conditions to clearly reflect the distribution of the boundary points of the Zonghai. For three-dimensional sea use, the Zonghai shall be drawn in accordance with the relevant requirements of this specification. The Zonghai that overlaps with the Zonghai shall be handled as the adjacent Zonghai. The overlapping part only reflects the map of the Zonghai. For examples of the compilation of the Zonghai boundary map, please refer to Appendix B.

5.4.2.1 Plan layout information of each sea area and its internal units of the same project The plan layout of the sea area should reflect the plan layout and position relationship between each sea area and its internal units of the same project. The plan layout of the sea area only compiles the boundary line and the map of the internal unit of the sea area.
