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.
