Question 1

Three independently established, well-distributed control marks are checked with a rover using the same RTK base. All occupations return fixed solutions, yet every position is approximately 0.45 m east of control. Northings and elevations agree within 0.01 m, and the distances between marks check independently. Reoccupations several hours later reproduce the pattern. Which fault best explains these results?

Accepted Answer

An incorrect easting assigned to the base station

Answer

An incorrect rover antenna height entered for all occupations

Answer

Multipath at each control mark from nearby reflective surfaces

Answer

Separate carrier-phase cycle slips during the three rover occupations

Question 2

A parcel's legally established boundary is the thread of a river. During a single flood, the river abruptly cuts a new channel across a bend, leaving the former channel readily identifiable. The governing law moves this boundary with gradual accretion but not with avulsion. Where is the boundary immediately after this event?

Accepted Answer

Along the river's thread immediately before the channel shift

Answer

Along the thread of the river's newly established active channel

Answer

Along the bank of the abandoned channel nearest the parcel

Answer

Along the recorded meander line used to approximate the riverbank

Question 3

A benchmark elevation is 100.000 m. From the first level setup, the crew records a 1.425 m backsight on the benchmark, a 1.870 m intermediate sight on a curb, and a 2.110 m foresight on turning point TP1. From the second setup, the backsight on TP1 is 0.980 m and the foresight on the ground at a pad stake is 1.365 m. The required finished elevation at the stake is 98.600 m. What cut or fill should be marked?

Accepted Answer

0.330 m cut

Answer

0.330 m fill

Answer

1.460 m cut

Answer

1.540 m fill

Question 4

Contours generated from a LiDAR-derived triangulated irregular network show a shallow swale where field observations confirm a sharply defined drainage ditch. Ground classification and the surveyed bank and invert elevations check correctly. Inspection shows triangle edges bridging across the ditch instead of following its banks and invert. What change addresses the surface-model defect?

Accepted Answer

Rebuild the TIN with the surveyed bank and invert breaklines

Answer

Reduce the contour interval while retaining the existing triangulation

Answer

Generate a finer raster by resampling elevations from the existing TIN

Answer

Smooth the existing surface to remove abrupt changes between triangles

Question 5

While staking a site on a hot afternoon, a crew member becomes confused, staggers, and cannot follow simple instructions. The worker is still sweating heavily. A colleague suggests treating this as heat exhaustion because the skin is not dry. The crew chief should immediately:

Accepted Answer

Call emergency services and begin rapid cooling in a shaded, cool area

Answer

Give an electrolyte drink in the shade and reassess after a short rest

Answer

Drive the worker to a clinic and postpone cooling until medical staff take over

Answer

Check body temperature before calling emergency services

Question 6

A design requires a State Plane grid distance of 750.000 m from control point A to stake B. The crew places B on the correct direction at a ground horizontal distance of 750.000 m. The combined factor, defined as grid distance divided by ground horizontal distance, is 0.999600 throughout the line; the field software applies no scale correction. How should B be repositioned, to the nearest millimetre?

Accepted Answer

Move B 0.300 m away from A

Answer

Move B 0.300 m toward A

Answer

Leave B at its present position

Answer

Move B 0.600 m away from A

Question 7

All physical traces of a PLSS quarter-section corner's original monument and accessories have disappeared. Two independent earlier survey records contain detailed ties made before its destruction. Measurements to surviving reference control recover one consistent original position, and an exhaustive evidence investigation finds no conflict. That position differs from the midpoint between the surviving section corners. The corner should be restored by:

Accepted Answer

Using the original position recovered from the reliable collateral evidence

Answer

Single-proportioning the measured distance between the section corners

Answer

Averaging the recovered position with the computed section-line midpoint

Answer

Double-proportioning from the four surrounding controlling section corners

Question 8

A valid calibration analysis estimates an EDM's mean distance error as +0.4 mm, with a two-sided 95% confidence interval from +0.2 mm to +0.6 mm. The acceptance requirement is that this entire interval lie within -2.0 mm to +2.0 mm. A reviewer proposes rejecting the instrument because the interval excludes zero. Which assessment is justified?

Accepted Answer

It meets the mean-error requirement, although the analysis detects a nonzero bias

Answer

Reject it; the detected bias makes the instrument fail this requirement

Answer

It meets the requirement because 95% of individual distance errors fall inside the reported interval

Answer

Compliance cannot be assessed until a repeated analysis produces an interval that includes zero

Question 9

An archived parcel dataset retains its original coordinate values but has lost its coordinate-system metadata. The accompanying survey records identify the datum realization, State Plane zone, and U.S. survey-foot units. A new deliverable must store coordinates in metres in the same realization and zone. Which workflow produces the required dataset?

Accepted Answer

Assign the documented source coordinate system, then project to the metre-based target system

Answer

Assign the metre-based coordinate system directly, leaving the coordinate values unchanged

Answer

Assign the foot-based coordinate system, then change only the map's display units to metres

Answer

Apply the project's ground-to-grid combined factor, then label the resulting coordinates as metres

Question 10

A simple circular highway curve has a radius of 600.00 ft and an intersection angle of 60 degrees. The tangent intersection, PI, is at station 25+00.00. There are no station equations, and stationing follows the completed alignment through the curve. Which station belongs on the point-of-tangency stake?

Accepted Answer

27+81.91

Answer

27+53.59

Answer

28+46.41

Answer

31+28.32
