| Data category | Format requirements | Encoding standard | Typical application |
|---|---|---|---|
| Attribute data | CSV text (GB18030) | RFC4180 specification | Boundary approval document management |

| Multimedia data | MP4/MP3/PDF | Three-level directory storage | Boundary survey process traceability |
Key technical specifications
Boundary coding system
Adopts hierarchical combination coding: provincial boundaries are 4 digits (such as the Beijing-Tianjin line "1112"), municipal boundaries are 6 digits (such as the Changsha-Zhuzhou line "430102"), and county boundaries are 8-10 digits (for example, the Wangcheng-Ningxiang line "43011282"). The coding rules strictly follow the GB/T2260 administrative division code.
Spatial data requirements
Must include four core fields: identification code (GUID), boundary code, boundary name, and boundary level. The topological relationship of the linear features must be completely closed.
Implementation Suggestions
- Data Collection Phase: It is necessary to collect 20 types of documents such as boundary survey agreements and joint inspection reports simultaneously. Multimedia files are named according to the "boundary name + content type + serial number" rule.
- When connecting to the system: Note that the multimedia fields in the attribute data use "|" to separate multiple files (such as: Beijing-Tianjin Line Previous Meetings Multimedia 01.mp4|02.mp4)
- Security Control: Confidential multimedia materials should be stored separately and encrypted, and marked as "not available" in the attribute data.
Standard Evolution Analysis
This standard unifies the exchange format and storage specification of administrative boundary data for the first time, making up for the system interoperability difficulties caused by the independent practices of various regions. Compared with traditional surveying and mapping data standards, it innovatively incorporates multimedia boundary survey process records into the standardized management system.
