LSIT TEST QUESTIONS WITH ACTUAL SOLUTIONS 2025/26 GRADED A+
ASSURED
What is the major advantage of dual-frequency over single-frequency GPS receivers?
A. precise measurements of longer baselines
B. observation of more satellites
C. observation in bad weather conditions
D. measurement in three deminsions - (Correct Answer) - A. precise measurements of longer
baselines
Dual-frequency GPS receivers collect data that can be used to model the ionospheric delay
and thereby compensate for its effects on the signal. Therefore, they may be used for
baselines of greater length and also require shorter observation times for comparable
precision, as compares to single-frequency receivers.
What method should be used to restore a lost southeast corner of Section 31 in a typical
township?
A. bearing-bearing intersection
B. single proportional measurement
C. double proportional measurement
D. record bearing and distance - (Correct Answer) - B. single proportional measurement
Since the southeast corner of Section 31 is on the township exterior, single proportional
measurement should be used to reestablish lost corners.
,The star Polaris is located in which constellation? - (Correct Answer) - . Ursa Minor
What is the length of one link of a Gunter chain? - (Correct Answer) - A Gunter's chain is 66ft in
length and is divided into 100 links. Therefore, each link is 0.66ft or 7.92 in
When sighting through a leveled instrument at a distant level rod, curvature of the earth would
have what effect on the rod reading? - (Correct Answer) - The rod reading would be greater due
to the constant dropping of the Earth's surface from the horizontal level line.
When sighting through a leveled instrument at a distant level rod, what would be the effect of
refraction on the rod reading? - (Correct Answer) - The rod reading would be less because
refraction has the opposite effect as curvature.
On a map developed from a Lambert projection, which of the following is true?
A. Meridians converge
B. Parallels are arcs of circles
C. Parallels are uniformly spaced
D. (A), (B), and (C) are true - (Correct Answer) - D. all of the above
On a lambert projection, meridians are sown as converging straight lines, while parallels are
shown as uniformly spaced arcs of circles.
,Which method should be used to restore a lost southwest corner of Section 31 in a typical
township?
A. bearing-bearing intersection
B. single proportional measurement
C. double proportional measurement
D. record bearing and distance - (Correct Answer) - C. double proportional measurement
Since the Southwest corner of Section 31 is the township corner, double proportional
measurements should be used to reestablish the corner.
Which of the following can be accomplished by the DMD method?
A. Balancing a closed traverse
B. correcting latitude observation
C. correcting longitude observation
D. determining area of a closed figure. - (Correct Answer) - D. determining area of a closed
figure.
DMD stands for Double Meridian Distance and describes a method for determining the area
of a closed figure.
In a closed traverse with the only significant error in measurement being one angular error, at
which station was the error most likely made? - (Correct Answer) - The perpendicular bisector of
the line of closure will point the traverse station where the error was probably made.
, A closed traverse has a total length of 2181.14 ft. and an error of closure of 0.37 ft. in the
northing and 0.24 ft. in the easting. What is the ratio of error for the closure?
A. 1:4957
B. 1:5187
C. 1:6319
D. 1:9453 - (Correct Answer) - A. 1:4957
error of closure=SQRT(DeltaNorthing^2+DeltaEasting^2)
Elevations provided for geodetic benchmarks are usually referenced to which datum?
A. mean tide level
B. mean sea level
C. National Geodetic Vertical Datum
D. North American Datum of 1927 - (Correct Answer) - C. National Geodetic Vertical Datum
What is the arc length of a highway curve with a radius of 954.93 ft, an interior angle of
60degrees, and the following stationing?
PC 23+45.67
PI 28+97
PT 33_45.67 - (Correct Answer) - 1000ft
