1 Scope

GB/T 18578-2025 is the Chinese national standard on specifications for designing urban geographic information system, 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 30 May 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 September 2025. 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 document specifies the general principles, design principles, requirements analysis, overall design, database design and detailed design of urban geographic information systems. Requirements for the plan. This document is applicable to the design of urban geographic information systems for different needs. The design of other geographic information systems can refer to this document. implement.
