(i) mathematics, (ii) legal principles, (iii) types of surveys and (iv) survey computations
Know these fo rsure
Survey Process and Methods - correct answer -Instrumentation (e.g., GNSS/GPS,
levels, total stations, robotic total stations, scanners, UAS)
-GNSS/GPS surveys (e.g., static, kinematic, OPUS, real-time networks)
-Control surveys (e.g., horizontal, vertical, network design, accuracy standards)
-Cadastral (e.g., Public Land Survey System [PLSS], boundary, metes and bounds, land
title)
-Topographic surveys
-Construction surveys (e.g., layout, as-built, quantity)
-Land development (e.g., subdivision design/platting, land use, environmental, flood
plains, wetlands)
-Field record keeping and documentation (e.g., procedures, field books,raw data files)
GNSS (Global Navigation Satellite System) - correct answer -Uses the Global
Positioning System (GPS),
GLONASS, and other space based satellite systems to measure latitude, longitude, and
altitude.
GNSS Equipment - correct answer -Ground based receivers and antennas are utilized
to collect electronic radio signals from the GNSS satellites.
-the receiver and antenna shall at a minimum collect
signals from the GPS satellites.
-The receivers shall be geodetic quality L1/L2 Dual Frequency with full-wavelength
capabilities and they must be capable of tracking satellites down to a 5-
degree elevation angle.

-The receivers shall record the full wavelength, carrier phase, and signal strength of
both the L1 and L2 frequencies, and track at least eight satellites simultaneously on
parallel channels.
GPS (Global Positioning System) - correct answer A system that determines the
precise location of something on Earth through a series of satellites, tracking stations,
and receivers.
Differential leveling - correct answer is the term applied to any method of measuring
directly with a graduated staff the difference in elevation between two or more points.
Precise leveling - correct answer is a particularly accurate method of differential
leveling which uses highly accurate levels and with a more rigorous observing
procedure than general engineering leveling.
-It aims to achieve high orders of accuracy such as 1 mm per 1 km traverse.
A level surface - correct answer is a surface which is everywhere perpendicular to the
direction of the force of gravity.
-An example is the surface of a completely still lake.
-For ordinary leveling, level surfaces at different
elevations can be considered to be parallel.
A level datum - correct answer is an arbitrary (random choice, no reason behind it)
level surface to which elevations are referred.
-Example the most common surveying datum is mean sea-level (MSL),
A reduced level - correct answer is the vertical distance between a survey point and
the adopted level datum.
-A bench mark (BM) is the term given to a definite, permanent accessible point of
known height above a
datum to which the height of other points can be referred.

QUESTIONS WITH ACTUAL SOLUTIONS

A set-up - correct answer refers the position of a level or other instrument at the time
in which a number of observations are made without mooring (keeping where it is,
able to move instrument) the instrument.
-The first observation is made to the known point and is
termed a backsight; the last observation is to the final point or the next to be measured
on the run, and
all other points are intermediates.
A run - correct answer is the leveling between two or more points measured in one
direction only. (think of slope rise over run)
-The outward run is from known to unknown points and the return run is the check
leveling in the opposite direction.
A close - correct answer is the difference between the starting level of the initial point
for the outward run (is from known to unknown points) and that determined at the end
of the return run (is the check leveling in the opposite direction).
-If the levels have been reduced correctly this value should be the same as the
difference between the sum of the rises and falls and also the difference between the
sum of the backsight and foresights.
Height of Collimation - correct answer is the elevation of the optical axis of the
telescope at the time of the setup.
The line of collimation - correct answer is the imaginary line at the elevation.
Total Stations - correct answer consist of electronic theodolite with a built-in distance
meter, allowing it to measure angles and distances and determine the positions and
heights of points
Robotic Total Stations - correct answer allows remote (from a distance) operation and
can perform far more calculations and inspections in less time than with a traditional
Total Station.
