IV — Observations and Data

A — Raw Compass Observations

B — Local-Attraction Analysis and Corrected Directions

C — Computed Coordinate Components and Closure

V — Computations and Assumptions

Coordinate components use corrected azimuth $\alpha$:

$$Lat=L\cos\alpha,\qquad Dep=L\sin\alpha$$

Linear error of closure:

$$LEC=\sqrt{(\sum Lat)^2+(\sum Dep)^2}=0.0707\text{ m}$$ $$\text{Relative precision}=\frac{P}{LEC}\approx1:2{,}572$$

Assumptions and conventions:

• Station A is the reference unaffected station for this model exercise.
• Corrected directions are whole-circle azimuths clockwise from magnetic north.
• Positive latitude is north; positive departure is east.
• Closure and relative precision use the unrounded internal components; recomputing from the displayed three-decimal components gives a slightly different rounded result.
• The result is a classroom quality indicator, not a cadastral accuracy certification.

VI — Remarks and Conclusions

A — Remarks

• Raw fore/back directions do not differ consistently by 180°, supporting the local-attraction diagnosis.
• Nearby metallic objects, needle settling, centering, sighting, and tape alignment are probable error sources.
• Raw magnetic observations remain visible after correction.

B — Conclusion

After documented local-attraction corrections, the traverse has a linear closure of 0.0707 m over a 181.90 m perimeter, or approximately 1:2,572. The corrected direction and closure tables provide a traceable classroom compass-traverse result.
