Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 37118—2018
| Standard Dimensions | Content Overview | Keywords |
|---|---|---|
| Conceptual Model | Geographic entities are composed of primitives, which are associated with each other through identification codes, in accordance with the GB/T13923 classification. | Geographic entities, primitives, identification codes, conceptual models |
| Data Organization | Organized in a spatially seamless and content-layered manner, including primitive tables and entity tables. | Data organization, primitive table, entity table, identification code rules |
| Geometric expression rules | Geometric expression of points, lines, surfaces, and bodies to ensure spatial connectivity and integrity. | Geometry types, point entities, line entities, surface entities |
Implementation suggestions
1. Data organization and management:
- Establish a unified geographic entity identification system to ensure uniqueness and traceability.
- Reasonably design the primitive table and entity table structure to support efficient data query and update.
2. Geometric expression and processing:
- Implement geometric operations of points, lines, surfaces, and bodies in the GIS system to ensure the accuracy of spatial data.
- Follow the geometric expression rules to ensure the integrity and connectivity of the objects.
3. Standard application and extension:
- Promote the application of this standard in the fields of natural resource management, urban planning, etc.
- Define and expand geographic entities according to requirements to ensure compliance with the specifications while meeting the needs of specific application scenarios.
