Foreword

All the technical contents of this standard is mandatory. This standard is proposed and managed by the State Bureau of Surveying and Mapping. This standard was drafted. the standardization of China Institute of Surveying and Mapping Institute, National Mapping Bureau, Beijing Municipal Design and Research Institute of Surveying and Mapping, State Home Basic Geographic Information Center, Research and Design Institute to build a comprehensive survey, National Mapping Product Quality Supervision and Testing Center, China Land Surveying Planning Institute, Zhejiang Bureau of Surveying and Mapping and the Nanjing Institute of Surveying and Mapping Survey. The main drafters of this standard. Li fame, Xiao year, India Jie, Chen Cho, Li Li, Wang Dan, Wei Zeng Yan, Xu Jianxin, Chenshao Qin SURVEYING AND Chu Wei Zheng. This standard is the first release.

In order to implement the provisions of the laws and regulations to protect the geographical information platform and related information system reliability and normative promote information Sharing and integration, safeguarding the interests of basic geographic information data producers and users of the standard is formulated. Basic geographic information data standard basic provisions

1 Scope

GB 21139-2007 is the Chinese national standard on basic requirements for standard data of fundamental geographic information, in the field of natural and applied sciences. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 30 August 2007 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 March 2008. Classification: ICS 07.040, CCS A75. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard mathematical basis, data content, production process and data identified four aspects of the provisions of the standard basic basic geographic information data Claim. This standard applies to the production of basic geographic information data standards, identification and use.
