National basic scale map schema Part 4. 1.250000 1.500000 1.1000000 topographic map1 ScopeThis part of GB/T 20257 specifies various features and grounds represented on the topographic maps of 1.250000, 1.500000, and 1.1000000. Symbols, notes, and outlines of the features, and the methods and basic requirements for using them. This section applies to the mapping of 1.250000, 1.500000, 1.1000000 topographic maps. Prepare geographic basemaps or surveys The ruler map can be used as reference.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 13989 national basic scale topographic map framing and numbering3 General regulations3.1 Classification of symbols 3.1.1 Scale symbol. The scale symbol of the feature can be scaled according to 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. Only the width dimension values are marked next to the symbols in this standard. 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. Beside the symbol in this standard Dimension symbol length and width size values. 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). Special symbol 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 to 0.1mm, the diameter of the point is 0.15mm, and the line length of the non-main part of the symbol is 0.3mm (such as the 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. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 20257.4-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 20257.4-2017_English as soon as possible, and keep you informed of the progress.
