In general, the symbol's line thickness is 0.15 mm, the dot width is (1.3 mm), and the length of the main part of the symbol is 1.6 mm. For the line segments represented by dashed lines, the actual part is 2.0 mm, the smaller part is 3.1 mm, and the smaller part is 1.0 mm. mm.

3.3.1 The direction point of independent feature symbols is perpendicular to the south map outline. 3.3.2 When the area of green land and agricultural land is large, the interval between the recommended numbers can be set aside or directly indicated by annotation. 3.4 There are two sizes of the pollution mark. It can be selected according to the size of the drawing. 3.5 Correct representation of symbols on the drawing
3.5. 1 There is one case of the derivative symbols listed in the wood formula b) not according to the scale symbol (the symbol is annotated with a scale): n) according to the scale symbol (the size is not annotated next to the symbol): according to the scale. The symbol that is not in accordance with the scale is used as an explanatory symbol. The explanatory symbol is required according to the requirements of 3.2. 3.5.2 Various quantitative indicators in the brief description. "Greater than" includes the number.

5.1 The national boundary shall be accurately drawn in accordance with the boundary treaties or boundary agreements formally signed by the state and their attached maps, in accordance with the actual position. The national boundary should be drawn continuously. The boundary stakes and monuments should be drawn according to the coordinate values and their numbers should be annotated. When three or two boundary stakes and monuments with the same number cannot be drawn according to the actual position on the map, they should be drawn with a small circle according to the actual relative position and their respective numbers should be annotated. All kinds of annotations on the national boundary line are detailed in the country and no national boundary symbols are allowed. If the national boundary is bounded by the center of the river or the main channel, when the national boundary symbol can be drawn within the river symbol, the national boundary symbol shall be drawn continuously at the center of the river or on the main channel line; when the national boundary symbol cannot be drawn within the river symbol, the national boundary symbol shall be drawn continuously and staggered on both sides of the river. The ownership of islands shall be marked with notes. If the national boundary is bounded by a shared river, the national boundary symbols shall be drawn staggered every 3 to 5 cm on both sides of the river. The ownership of islands shall be marked with notes. If the national boundary is bounded by one side of a river or linear feature, the national boundary symbol shall be drawn continuously on the corresponding side. 5.2~5.5 The boundaries of provinces, autonomous regions, municipalities directly under the Central Government, autonomous prefectures, regions, prefecture-level cities, districts directly under the Central Government, counties, autonomous counties, banners, county cities, districts, townships, and other administrative divisions at all levels shall be accurately drawn with corresponding symbols. a.

The short teeth face the inside of the protected area. 6
Hill boundaries and other boundaries
6.1 Hill boundaries include fixed, undetermined, and branch hill boundaries within a combined hill. t: Hill boundaries with fixed boundary markers are indicated by this symbol: b. Hill boundaries without fixed boundary markers or hill boundaries are disputed and unclear, and are indicated by undetermined boundaries, L. All branch hill boundaries within a combined hill are indicated by this symbol. 2 Real estate area boundaries are indicated by this symbol.
3 Real estate subdivision boundaries are indicated by this symbol.
6.4 Different land use classification lines within a hill or a plot are indicated by land class boundaries. 6.5 The boundary of the hill is bounded by the side of the wall, and the side of the wall is represented by the boundary of the hill; the boundary of the hill is bounded by the center of the wall, and the boundary of the hill is drawn from the middle of the wall.

6. 6 The boundary of the property right includes the property right boundary, the undetermined boundary and the wall boundary of the adjacent house. If the property right boundary is disputed or unclear, the undetermined boundary line shall be used to indicate the property right boundary. For the property right boundary of the adjacent house, the boundary is the wall side, and the short teeth are drawn toward the property side, indicating the self-owned wall. The other side indicates the borrowed wall; the center of the wall is the boundary, and the short teeth are drawn toward both sides, indicating the shared wall. When the length of the property boundary is less than 3 cm, two short lines can be drawn. When the length is greater than 3 cm, short lines can be drawn at intervals of 1.0-2.0 cm: the short line is 1.0 mm longer than the property boundary.
6 If the boundary is bounded by a fence, a fence, or a wire mesh, the solid line is represented by a hill boundary symbol, and the short tooth symbol faces the side of the space, and the shared one faces both sides.
6.8 If the hill boundary is bounded by a ditch or a river, the ditch or river side is represented by the hill boundary, and the flow direction symbol is drawn on the side of the property. If the hill boundary is bounded by the center of the ditch or the stream, the hill boundary is drawn at the center of the symbol, and the flow direction symbol is drawn on the hill boundary.

The number of floors (the year of construction will be added on the hill map) code, and the different floors in the same building are drawn with solid lines; the code is marked in A4.A5 in Appendix A of 1GB/T17986.1-2000! 7.2 Overhead houses refer to houses with the bottom floor overhead and supported by supports. The overhead parts are generally passages, water areas or slopes. According to the house! The outer contour is surveyed and mapped, and the content specified in 7. is noted in the contour. The small circle at the corner represents the pillar. , 7.3 refers to the case hole for living. The dense hole on the ground is indicated by the true direction. The position of the case hole pit under the ground is measured and a symbol is drawn in the pit. !
