V — Computations and Assumptions

Angular closure for a four-sided polygon:

$$\sum\theta_{\mathrm{theoretical}}=(4-2)(180^\circ)=360^\circ$$

The observed sum is exactly $360^\circ00'00''$, so the model applies no angular correction.

Linear closure:

$$LEC=\sqrt{(0.0072)^2+(0.0052)^2}=0.00888\text{ m}\approx0.00887\text{ m}$$ $$\text{Relative precision}=\frac{280.009}{0.00887}\approx1:31{,}557$$

Bowditch corrections for course length $L_i$ and perimeter $P$:

$$C_{Lat,i}=-\sum Lat\left(\frac{L_i}{P}\right),\qquad C_{Dep,i}=-\sum Dep\left(\frac{L_i}{P}\right)$$

Assumptions and conventions:

• Coordinates use an assumed local system with Station A fixed.
• Positive latitude is north; positive departure is east.
• The prism constant is 0 mm and entered correctly.
• Bowditch adjustment is appropriate because angular and distance observations are treated as having comparable relative quality.
• Displayed correction sums use unrounded internal values; table entries are rounded for reporting.

VI — Remarks and Conclusions

A — Remarks

• The angular observations close exactly in the model dataset.
• Centering, prism-pole plumbing, target pointing, atmospheric conditions, and instrument/prism settings are probable error sources.
• Unadjusted observations and components remain visible after adjustment.

B — Conclusion

The unadjusted traverse closes by 0.00887 m (8.87 mm) over 280.009 m, equivalent to approximately 1:31,557. After Bowditch adjustment, latitude and departure sums are zero and the coordinates return to Station A.
