Foreword

This standard replaces GB/T 17278-1998 "digital topographic map products" and GB/T 18315-2001 "digital topographic map series and basic requirements". This standard and GB /and GB/T 18315-2001, compared T 17278-1998 main changes are as follows:

a) change the name of the standard.

b) changing the structure of the standard, the standard of the technical elements in reference to ISO 19131.2007 "Digital Geographic Information Product Specifications" Structure. The change does not affect the references GB/T 17278-1998 "digital topographic map products" and GB/T 18315-2001 "digital topographic map series and basic requirements of the" standard of the relevant national and industry standards, but the relevant standard An updated version of this standard should be cited.

c) basic coverage of the GB/T 17278-1998 and content GB/T 18315-2001 two standards, canceled to scale classification.

d) Added Appendix A, Appendix B. This standard Annex A, Annex B is informative appendix. This standard was proposed by the State Bureau of Surveying and Mapping. This standard by the National Standardization Technical Committee on Geographical Information (SAC/TC230) centralized. This standard was drafted. Chinese Academy of Surveying and Mapping, National Mapping Bureau of Surveying and Mapping Standardization Institute, the National Basic Geographic Information Center, built Let Comprehensive Survey Research and Design Institute.

1 Scope

GB/T 17278-2009 is the Chinese national standard on basic requirements for products of digital topographic map, 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 May 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 October 2009.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the basic requirements of digital topographic map products classification, composition, product identification, content structure, data quality and other aspects. This standard applies to digital topographic map of product development and production, and other digital map products available for implementation.
