Foreword
This standard replaces GB/T 16818-1997. This standard compared with GB/T 16818-1997, major changes include.
--- According to GB/T 1.1-2000 "Standardization Guide Part 1. Standard structure and write rules" of the original standard grid
The formula has been modified;
--- Modification and adjustment of the "four basic requirements";
--- Deletion of the requirement of point;
--- Modify the documentation requirements;
--- Modify the outcome of the consolidation and turned over the contents;
--- Deleted Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F.
This standard was proposed by the State Bureau of Surveying and Mapping.
This standard by the National Standardization Technical Committee on Geographical Information.
This standard was drafted. National Mapping Bureau of Surveying and Mapping Standardization Institute.
The main drafters of this standard. Shaw school year, Zhu Jian, Rendao Sheng.
This standard replaces the standards previously issued as follows.
--- ZBA76002-1987;
--- GB/T 16818-1997.
The short-range optical distance specifications
1 Scope
This standard specifies the use of the measuring range is within 15km of EDM (including total station) in progress, and the level of short distance measurement
Accuracy requirements, technical methods, workflow and distance calculation method.
This standard applies to control survey, topographic survey, engineering survey and other measurement operations, the short-range optical distance.
2 Normative references
Following standard terms of this standard reference and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

3 Symbol
Symbols used in this standard as follows.
D '--- observation distance in meters (m);
D --- by measuring the corrected slope distance in meters (m);
D0 --- straight chord length in meters (m);
D1 --- horizontal distance or the reference ellipsoid of the chord length, in meters (m);
D2 --- horizontal distance or reference ellipsoid arc length in meters (m);
H1, H2 --- measuring point reference ellipsoid height in meters (m); ellipsoid elevation in place of normal height;
K --- refraction coefficient (≈0.13);
4 Basic requirements
4.1 EDM (hereinafter referred to as DME) divided by the measurement range, a short distance rangefinder. Odometry 3km within a short distance of the
Instrument, measuring range 3km ~ 15km of medium-range finder, measuring range is more than 15km distance rangefinder. Press rangefinder factory standard differential is nominal,
Imputed to 1km ranging standard deviation calculation accuracy divided into four levels (see Table 1).

Ranging accuracy class standard deviation
NOTE. D is the distance measurement unit in kilometers (km).
