Introduction
Analysis of the core content of the standard
| Technical elements | Requirements of the 2011 version | Updates to the 2020 version |
|---|---|---|
| Coordinate system | Coexistence of multiple datums | Mandatory use of the CGCS2000 coordinate system |
| Control network level | Unclear classification | Three-level division (relative mean error of the weakest side 1/300,000~1/100,000) |
| GNSS equipment | Only basic parameters are specified | Newly added Beidou Ground-Based Augmentation System Technical Requirements |
Key Technical Indicators
Physical point accuracy requirements: The mean error of the plane position of 3D seismic exploration is ≤1.0m (flat land), and the mean error of elevation is controlled according to the terrain slope grade. It is allowed to be relaxed to ±0.6m in mountainous conditions.
Construction conductor layout: The relative closure error of the full length of the first-level conductor is ≤1/10000, and a total station with an angular measurement accuracy of 3″ is required; the second-level conductor is allowed to use 6″ equipment.
Implementation Suggestions
- Give priority to using the national CORS station to establish a work area control network, and use Qianxun location services in difficult areas
- RTK fixed solutions should be used for physical point measurement, and floating point solutions in jungle areas need to be manually verified for terrain consistency
- Electronic data are stored in the "year-team number" directory, and editing of original data is prohibited
