✍️ Sample PS Questions & Answers
1. In traverse computation, the term 'departure' specifically refers to:
Departure is the horizontal east-west component of a traverse course; latitude is the north-south component.
2. A geodetic survey finds a height difference of +2.352 m between two benchmarks using spirit leveling. This is best described as a difference in:
Spirit leveling directly determines orthometric height differences referenced to the geoid (gravity field), not ellipsoidal heights.
3. What type of map projection preserves the shape of small areas but distorts area over large regions?
Conformal projections preserve local angles and shapes, but they distort area as distance from the central meridian increases.
4. A closed traverse has ΣLat = +0.42 ft and ΣDep = −0.31 ft. What is the linear error of closure (LEC)?
LEC = √(0.42² + 0.31²) = √(0.1764 + 0.0961) = √0.2725 ≈ 0.52 ft.
5. What is the primary ethical obligation of a PS professional when a conflict of interest arises during geodetic datums & coordinate systems activities?
The primary ethical obligation when a conflict of interest arises in geodetic datums & coordinate systems is to disclose it to all relevant parties and, if necessary, recuse from the decision. This maintains professional integrity and stakeholder trust.
6. What is the primary ethical obligation of a PS professional when a conflict of interest arises during boundary law & riparian rights activities?
The primary ethical obligation when a conflict of interest arises in boundary law & riparian rights is to disclose it to all relevant parties and, if necessary, recuse from the decision. This maintains professional integrity and stakeholder trust.
