LAC 43:XXVII.517. Survey Adjustments

A. Individual horizontal closed traverse loops or individual traverse lines originating from and returning to existing permanent horizontal control monuments, shall be adjusted to proportionally distribute any discrepancies by either compass rule or least squares adjustment methods, at the discretion of the surveyor. B. Integrated traverse, triangulation and/or GPS loop network configurations resulting in potential conjugate redundancy shall be properly evaluated and adjusted to minimize residual discrepancies by minimally constrained 3-D least squares adjustment methods only. C. Individual closed level line loops or individual level lines originating from and returning to existing permanent vertical control benchmarks shall be adjusted to proportionally distribute discrepancies along the length of individual level lines run.
