✍️ Sample LSIT Questions & Answers
1. Which systematic error in EDM instruments is best detected by measuring over a calibrated baseline of multiple lengths?
Cyclic (scale) errors repeat over fixed distance intervals and are revealed by comparing EDM measurements to a known baseline at multiple distances.
2. A licensed surveyor discovers that a neighboring surveyor's recent boundary survey contains a significant mathematical error. What is the ethical obligation under NSPS and most state codes?
Professional codes require surveyors to protect the public interest, which includes reporting known errors that could cause harm to clients or the public.
3. When using a total station, 'face left' and 'face right' observations are averaged primarily to eliminate:
Observing in both face-left and face-right positions and averaging the results cancels out systematic errors such as collimation error and horizontal axis tilt.
4. Which map projection is used by the US State Plane Coordinate System for states with a predominantly east-west extent?
Lambert Conformal Conic is used for east-west oriented states/zones because it minimizes distortion along parallels.
5. The geodetic datum NAD 83 is referenced to which ellipsoid?
NAD 83 is based on the Geodetic Reference System 1980 (GRS 80) ellipsoid, though it is nearly identical to the WGS 84 ellipsoid used by GPS.
