Professional scope
- Not survey, geodetic or engineering certification.
- Absolute accuracy claims require suitable independent reference evidence.
- Uncertainty results are conditional on the supplied vertical-error model.
- Fitness thresholds must ultimately be matched to the client decision and project acceptance criteria.
