Foreword

GB/T 12343 "national basic scale map compilation specification" is divided into three parts.

--- Part 1. 1.25000 1.50000 1.100000 topographic map compilation specification;

--- Part 2. 1.250000 topographic map compilation specification;

--- Part 3. 1.500000 1000000 topographic map compilation specification. This section GB/T 12343 Part 3. This Part replaces GB 14512-1993 "1.1000000 topographic map compilation specification And drawings "in the compilation Specifications section. This section compared with GB 14512-1993 main changes are as follows:

--- According to GB/T 1.1-2000 standard format revision;

--- Increase in GB/T 20257.4 topographic map illustrated in the increase in the "elements of a comprehensive topographic map indicating the basic requirements" section Select indicators were elements of the index and select some of the elements of the feature to make appropriate changes;

--- In the "compilation methods and technical requirements" section increases the flow chart and topographic map compilation "first element selected resymbolize Edit" and The traditional method of operation 'element selection and editing symbols simultaneously, "the compilation method, delete pavilion, collages, scale series and so on;

--- In the "Preliminary work" section to remove the Description field Editorial Design book about job carving clear methods;

--- Now use the potential of the information from "off to a printed picture before sending Factory" to "before the deadline to submit a diagram acceptance";

--- Delete the original standard Chapter 6, "Printing picture production," and Chapter 7, "printed map" section. This section of Appendix A normative appendix. This part by the State Bureau of Surveying and Mapping. This part of the National Standardization Technical Committee centralized geographic information. This in part by the National Mapping Bureau of Surveying and Mapping Institute of Standardization responsible for drafting. The main drafters of this section. Ma Xiaoping, Xiao Guoxiong, Liu Xiaoqiang. This part of the standard replaces the previous editions are.

Topographic map compilation specifications national standards GB 12343 "1.25000 1.50000 topographic map compilation norms", GB 12344 "1.100000 Topographic map compilation norms ", GB 15944" 1.250000 topographic map compilation specification and drawings ", GB/T 14512" 1.1000000 topographic map Compilation specification and drawings, "and industry standards CH/T 4011" 1.500000 topographic map compilation specification and drawings "has been implemented for many years, they are in my National economy construction and mapping production work has played an important role. In order to adapt to the digital mapping production needs to keep up with the corresponding ratio Coordination cases Topographical Map scale standard structure, it is necessary to adjust the structure of topographic map compilation standard specification. After the restructuring, such as Introduction Said. This part is a complete revision after GB 14512-1993.

1 Scope

GB/T 12343.3-2009 is the Chinese national standard on compilation specifications for national fundamental scale maps - part 3: compilation specifications for 1:500 000 1:1 000 000 topographic maps, in the field of natural and applied sciences. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 6 February 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 June 2009.
