Foreword

This standard replaces GB 12341-1990 "1.25000,1.50000,1.100000 topographic map Aerophotogrammetry outside the industry norm." this standard compared with GB 12341-1990 main changes are as follows.

--- According to GB/T 1.1-2000 "Standardization Guide Part 1. Standard structure and drafting of rules" were the standard Amendment;

--- Modify the scope of the standard;

--- Increased eight normative references;

--- Topographic map specifications for the content has been modified;

--- Increased tone paint content.

The standard Appendix C, Appendix D, Appendix E, Appendix F, Appendix G are normative appendices.

The Standard Appendix A, Appendix B is an informative annex.

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.

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.
