Least-squares adjustment for survey networks (2D, 1D leveling, 3D GNSS, mixed) with robust estimation, statistics, and reliability analysis.
Production-ready least-squares adjustment plugin for professional surveying workflows.
Features:
- 2D Classical Adjustment (distances, directions, angles)
- 1D Leveling Adjustment (height differences)
- 3D GNSS Baseline Adjustment (with full covariance)
- Mixed Adjustment (classical + GNSS + leveling combined)
- Robust Estimation via IRLS (Huber, Danish, IGG-III)
- Constraint Health Analysis with actionable messages
- Optional Auto-Datum for quick exploration
- Chi-square global test, redundancy numbers, MDB, external reliability
- Error ellipses with confidence scaling
- JSON + HTML reports
- GeoPackage output with adjusted points, ellipses, residual vectors
