1 Scope
This part of GB/T 20257 specifies the symbols and notes of various features and geomorphological elements represented on the 1.5000 and 1.10000 topographic maps.
Remarks and frame finishing, as well as the use of these symbolic methods and basic requirements.
This section applies to the mapping of 1.5000, 1.10000 topographic maps. The preparation of the geographical base map can be used as reference.

3 General regulations
3.1 Classification of symbols
3.1.1 Scale symbol. When the feature is reduced by the scale, its length and width can be expressed by the scale symbol.
3.1.2 Semi-scale symbol. After the scale is reduced by the scale, the length can be scaled and the width cannot be expressed by the scale.
number. Mark the width dimension value next to the symbol.
3.1.3 Not according to the scale symbol. After the scale is reduced by the scale, its length and width cannot be expressed by scale. Marker symbol next to the symbol
Inch value.
3.2 Symbol size
3.2.1 The size values marked with numbers next to the symbols are in millimeters (mm).
3.2.2 Only one dimension value is placed next to the symbol, indicating the diameter of the circle or circumcircle, the length of the equilateral triangle or the square; the two size values are
For the column, the first number indicates the height of the main part of the symbol, the second number indicates the width of the main part of the symbol; the number of one end of the line symbol
Word, single line refers to its thickness, and two parallel lines refer to the width of the line (the street refers to the width of the blank part). Need special mark on the symbol
The size value of the note is indicated by a dotted line.
3.2.3 The thickness of the symbol line, the length of the line segment and the angle of the intersecting line segment, etc., are not marked with the symbol of this figure. general
In the case, the line is thicker by 0.12 mm, the diameter of the point is 0.2 mm, and the line length of the non-main part of the symbol is 0.4 mm (such as a steep and short line).
The angle of the vertical intersecting line segment is 45° or 60°.
3.3 Symbol positioning
3.3.1 There is a point in the symbol graph, which is the physical center position of the feature.
3.3.2 Symbols such as circles, squares, and rectangles, and the positioning point is at the center of its geometry.
3.3.3 The wide-bottom symbol (yurt, chimney, water tower, etc.) is located at the center of its bottom line.
3.3.4 The symbol with the right angle at the bottom (windmill, road sign, independent tree, etc.) locates the apex at its right angle.
