GB/T 28585-2025 Geographic information—Methodology for feature cataloguing

Scope

This document describes the method of cataloging element types, and specifies the way to organize element types into an element catalog and provide them to users of geographic data sets.
This document is applicable to establishing an element catalog for uncataloged element types, revising existing element catalogs, and cataloging element types represented in digital form. The cataloging principles are also applicable to the cataloging of other forms of geographic data. The element catalog is independent of the element concept dictionary defined in ISO 19126, and cataloging can be carried out without using or establishing an element concept dictionary. This document is also applicable to defining geographic elements at the type level, but not to representing individual instances of each element type, and it does not involve the illustrative expression mode specified in ISO 19117.
This document serves as the basis for defining the domain in specific applications, or for standardizing the general characteristics of real-world elements in the modeling of multiple applications.
