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 dimensions - 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.
In terrain modeling, TIN stands for - correct answer Triangulated Irregular Network
A surveyor's compass measures - correct answer bearings
a surveyors compass is divided into 4 quadrants, each 90 degrees.
Written contracts are required because of:
A. Administrative code
B. Common law
C. the Statute of Frauds
D. The Statute of Limitations - correct answer C. the Statute of Frauds
The statute of frauds requires that certain contracts must be written in order to be
valid.

An error ellipse is the two-dimensional uncertainty in a point's position as determined
from a least squares adjustment. The probability level of a standard error ellipse is
approximately:
A. 68%
B. 35-39%
C. 90%
D. 05% - correct answer B. 35-39%
The standard error ellipse is a bivariate distribution - from the easting standard
deviation and northing standard deviation. When combined, the 2D error ellipse has a
probability level of 35-39%.
A total station is setup 5.65ft above point J whose elevation is 1869.05ft. It is used to
measure a 759.63ft slope distance at a zenith angle of 91degree20'30" to a pole
mounted reflector 6.89ft above point K. What is the elevation difference from point J to
point K
A. -19.79ft
B. -19.03ft
C. -24.68ft
D. -23.44ft - correct answer B. -19.03ft
At a station along a road alignment, the _______ location is where the original and
finished cross-sections intersect perpendicular to the center line.
A. offset
B. reference
C. slope stake
D. balance point - correct answer C. slope stake
The intersection of original and finished cross-sections indicated where the finished
cross-slope replaces the original. It defined the construction limits in the respective
side of center-line. This is the traditional slope stake location.
If deemed lost, the southeast corner of a non-fractional Section 13 would be re-
established by:
A. one-point control
B. single proportionate measurement

C. double proportionate measurement
D. common report - correct answer B. single proportionate measurement
The east line of Section 13 is a Township line which has a higher precedence than the
south line of the Section. Therefore, the corner would be re-established by single
proportionate measurement north and south along the Township line.
How many significant figures are in 6140?
A. 2
B. 1
C. 4
D. 3 - correct answer D. 3
All non-zero numbers are significant. Because there is no expressed decimal point, 0
is not significant.
The owner of a parcel sold off two parts of it in 1965 and 1968 and retained the
remainder. Which parcel is the most senior one? - correct answer The 1965 parcel
This is a series of sequential conveyances. General rule is " Both are senior to the
remainder of the original parcel. Why? Because the original parcel must provide for
each part conveyed from it. Here, the individuals who too title from the parent parcel's
own are entitled to the full extent of their deed's conveyance. Any deficiency would be
made up by the remainder.
How are the areas of quarter quarter sections along the North line of section 5
determined? - correct answer They are computed based on accumulated survey errors
in the east and west lines of section 5.
How do you compute grid length from an NSRS datasheet? - correct answer
Grid=Ground*Combined Factor
In a State Plane Coordinate System, the grid scale factor is the ratio of the distance
distortion between the _______ and the ______.
A. ground, grid
B. ground, geoid
C. ground, ellipsoid
