1 Scope

GB/T 12340-2008 is the Chinese national standard on specifications for aerophotogrammetric office operation of 1:25 000 1:50 000 1:100 000 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 20 June 2008 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 December 2008. Classification: ICS 07.040, CCS A77. 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 specifies the use of simulation, analytical photogrammetry method Topographic mapping 1.25000,1.50000,1.100000 Specifications, precision and within the industry, the basic requirements of the job. This standard applies to aerial photogrammetry 1.25000,1.50000,1.100000 Topographic jobs within the industry.
