Introduction
Analysis of the core content of the standard
| Technical module | Main specifications | Implementation points |
|---|---|---|
| Data classification | Basic geography/geology/other related data | Adopting the multidimensional classification method of region-map-theme-element |
| Accuracy requirements | Plane tolerance ≤0.5mm (1:500) | Needs to match the "Urban Surveying Specification" CJJ/T8 |
| 3D modeling | Geological body LOD classification | Needs to support collision analysis with underground facility models |
Evolution of key technologies
Compared with the 2012 version of the standard, this revision adds:
- Geological 3D model data standardization requirements (Article 4.3.9)
- WPS network processing service interface specifications (Article 9.3.4)
- Technical terms for privacy processing of real-life maps (Article 4.4.10)
Implementation suggestions
Data database construction process optimization
It is recommended to adopt the "physical seamless + logical blocking" hybrid storage strategy:
- Vector data: feature-level update (Article 6.3.6 of the standard)
- Raster data: build a multi-level pyramid (Article 6.3.7 of the standard)
System security protection
Requires simultaneous deployment:
- Geographic data digital watermark (Article 7.3.5 of the standard)
- Two-factor identity authentication (Article 8.1.4 of the standard)
