Foreword

This standard replaces GB 7930-1987 "1.500 1.1000 1.2000 within the topographic map and aerial photogrammetry industry norms." this standard compared with GB 7930-1987, the content changes include.

--- Standard style, the wording of the statement in accordance with GB/T 1.1-2000 made comprehensive revisions.

--- Increase the scope, normative references.

--- 1.1.1 The original standard was amended plane coordinate system shall be prescribed by the State unified coordinate system; when really necessary, can be used Legally approved independent coordinate system. Projection, elevation system according to GB/T 18315 execution.

--- 1.1.2 The original standard was revised topographic map of subdivision and numbered GB/T 20257.1 execution.

--- 1.1.6 original standard was revised topographic map symbols and annotation specifications according to GB/T 20257.1 execution.

--- The original 1.4 standard has been modified, aerial information should meet the requirements of GB/T 6962's.

1.6 --- original standard was revised, prepared according to the provisions of CH/T 1004 technical design book.

--- In Chapter 2, the original standard was added to the color photographic processing.

--- The original 8.1 standard has been modified, aerial mapping products within the industry, according to CH1002, CH1003 provisions of inspection and acceptance.

--- Increased 10.1 Technical Summary.

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.

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 of this standard revision process, proven correct fit Management of technical methods and specifications shall be maintained on the relevant standards and uncoordinated content has been modified. About new technologies and new methods Further development of standards.
