Introduction

With the development of science and technology, tremendous changes in production technology and mapping systems occurred. In order to maintain the integrity of the original technology system, now Systematic coordination between the standard and the standard system, the integrity, the standard revision process, proven correct and reasonable Technical methods and specifications shall be maintained on the relevant standards and uncoordinated content has been modified. New technologies and methods related to another Line established. 1.25000 1.50000 1.100000 Topographic map aerophotogrammetry outside the industry norm

1 Scope

This standard specifies the use of simulation, analytical photogrammetry method Topographic mapping 1.25000,1.50000,1.100000 Outside the industry, the basic requirements of the job. This standard applies to 1.25000,1.50000,1.100000 topographic maps and aerial photogrammetry production operations outside the industry.

3 General

3.1 specification topographic map 3.1.1 Spatial Reference System The state plane coordinate system uses a unified coordinate system; while, if necessary, can be used according to the law approved by the independent coordinate system. Projection, high Drive system according to GB/T 18315 execution. 3.1.2 Framing and Numbers Framing and numbered GB/T 13989 execution. 3.1.3 The basic contour interval The basic contour interval by GB/T 18315 execution. Press terrain category within Mapsheet range most of the ground slope and elevation divided (see Table 1). When the height and slope of the ground conflict, the slope of the ground prevail. A picture should adopt a basic contour interval, the basic contour interval does not indicate relief Features should be added between the measured curve and help curve. 3.1.4 Elevation Note Elevation Note the obvious point should be selected in the feature point and the terrain feature points, its density is within the figure per 100cm2, plains, hills 10 ~ 20, mountains, alpine terrain and ground feature points sparse areas of 8 to 15. Elevation Annotation in meters, 1.25000 mapping should note to 0.1m, 1.50000,1.100000 mapping should note to the whole meter. 3.1.5 Symbols and Notes Symbols of topographic maps and a variety of annotation according to GB/T 20257.3 of.
