3 General

3.1 Topographic Map Specification 3.1.1 spatial coordinate system Plane coordinate system should be used to coordinate a unified state; independent coordinate system when strictly necessary, can be legally approved. Projection, high Drive system according to GB/T 18315 execution. 3.1.2 topographic map of subdivision and number Framing and numbered GB/T 20257.1 execution. 3.1.3 Terrain category Ground. the vast majority of the ground slope at 2 ° the following areas; Hills. most of the ground slope between 2 ° ~ 6 ° area; Mountain. the vast majority of ground slope between 6 ° ~ 25 ° in the region; Alpine to. the vast majority of the ground slope at 25 ° above areas. 3.1.4 The basic contour interval The basic contour interval based on type of terrain, the provisions in Table 1, the general use of a picture within a basic contour intervals. When the basic contours not When can show topographical features should be added between the measured curve, can be combined with the measured curve to help when necessary. Flat area, according to Fig needs, may not draw contour lines, only elevation annotation dots.
