If your ROCK Cloud project displays unexpected offsets, they are often caused by GNSS data issues or poor base station conditions. Checking your processing report and ensuring a proper GNSS environment can help identify and resolve these misalignments.
"Examine data overlap using GPS time and view your point cloud from ground level to pinpoint offset areas."
Common Causes of Offsets:
- Inconsistent GNSS data or poor satellite coverage
- Base station obstructions (vehicles, fences, towers)
- Limited satellite constellations in your data
How to Identify and Fix Offsets:
-
View Overlaps:
- Use GPS time visualization in ROCK Cloud.
- Check overlaps between flight passes.
-
Examine the Processing Report:
- Access the report after uploading data to ROCK Cloud.
- Look for drops in satellite counts or missing constellations.
-
Reprocess With Better Data:
- Consider using publicly available RINEX data meeting recommended specifications.
- Re-run processing to see if offsets disappear.
-
Check Environment:
- Ensure takeoff and landing areas are free from GNSS obstructions.
- Follow best practices for mission planning.
Additional Resources:
- Optimize point cloud generation with strip selection.
- Improve data accuracy through proper camera calibration.
- Consider upgrading your setup with the R3 Pro V2 for precision surveying.
