Which statement about an open traverse is correct?
Correct answer: A. It does not normally provide a complete closure check
- A. It does not normally provide a complete closure check
- B. It starts and ends at the same station
- C. It always provides an angular check
- D. It must contain exactly three survey lines
Explanation
An open traverse does not close on a known station or another known control point, so its angular and linear closure checks are generally unavailable. It is commonly used for routes such as roads, canals and pipelines.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
