Basic Geographic Information Element Classification and Code
1 Scope
This document specifies the classification and coding principles, classification schemes, coding schemes, and classification and code extension principles of basic geographic information elements.
Numerically identifies the type of underlying geographic information feature.
This document applies to the collection, update, management, distribution, expression and application services of basic geographic information data, including basic geographic information
Database construction and application, basic geographic information public platform construction, basic geographic information exchange and sharing between different systems, and digitalization
Mapping, editing and map updating, etc.

4 Classification and coding principles
4.1 Scientific
With the goal of being suitable for the application and management of modern computer and database technology, scientific research is carried out according to the element characteristics or attributes of basic geographic information.
classification, forming a systematic classification system.
4.2 System Consistency
The same feature has a consistent classification and unique code in the underlying geographic information database.
4.3 Stability
The classification system selects the most stable characteristics and attributes of each element as the classification basis, and can not undergo major changes for a long time.
