Introduction
Analysis of the core content of the standard
Key Technical Indicators
| Project | Plain Area | Special Terrain | Surveying Method |
|---|---|---|---|
| Plane Error | ≤±2m | ≤±5m | GPS/RTK |
| Elevation Error | ≤±2m | ≤±5m | Geoid Fitting |
| Boundary Map Scale | Priority 1:10000 | Aerial Survey/Remote Sensing | |
Detailed explanation of implementation process
- Preparation: Collect approval documents, 1:10000 topographic maps, remote sensing images (resolution ≤1m)
- Boundary preset: Set a calibration point every 5-10km, and stakes must be set at key turning points
- Field survey: Use RTK measuring instrument to obtain CGCS2000 coordinates
- Result production: The boundary map must include 16 azimuths and directions (see Appendix C)
Qilian Mountain National Park Application Case
The park uses UAV aerial survey completed complex mountain boundary surveys, set up a total of 217 boundary stakes, of which three stakes with the same number accounted for 12%. The rationality of the boundary was verified through a three-dimensional scene model, reducing the area of the disputed area by 23 hectares.
Solutions to common problems
Q: How to define the river boundary?
A: It is necessary to clearly define the center line or shoreline as the boundary, and the water level impact needs to be reviewed during the flood season. Floating boundary stakes should be equipped with electronic markers.
Q: The historical approved coordinates do not match the current site?
A: The latest surveying and mapping results shall prevail, and the reasons for the differences shall be specifically stated in the boundary survey report.
