Self Study: Traverse Adjustment
Carry adjusted lats, deps, and dists to 0.001', directions to 0.1" to minimize rounding errors.
Problem (1)
| Unadjusted | ||||
| Line | Direction | Length (ft) | Latitude | Departure |
| 101-102 | S36°00'00"E | 379.25 | -306.820 | +222.918 |
| 102-103 | S75°23'18"W | 408.90 | -103.152 | -395.675 |
| 103-104 | N14°43'29"W | 298.65 | +288.842 | -75.909 |
| 104-101 | N63°59'20"E | 276.55 | +121.280 | +248.538 |
(a) Compute linear closure and precision
(b) Adjust the latitudes and departures using the Compass Rule
(c) Compute the adjusted lengths and directions
