GE 114-TOPIC 2 EXAM QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
precise position; stations; large area - Answers Control surveying is referred to as the determination
of the _____ _____ of a number of _____ which are distributed over a _____ _____.
topographic and hydrographic - Answers The established stations of the system serve as the basis for
originating or checking other subordinate surveys for engineering projects such as _________ and
_________ mapping; planning, design, and layout of highways and rail roads; delineation of property
or political boundaries. (Putt, 1990)
vertical and horizontal; three dimensional - Answers Mine surveys are done with both ______ and
_______ control, locating the features in a _____ _________ manner.
Types of Control Surveys - Answers Horizontal Control
o Control by Traversing
o Control by Triangulation
o Control by Trilateration
Vertical Control
o Control by Leveling
Horizontal Control - Answers Horizontal control surveys coordinate horizontal positional data. These
positions can be referenced by parallels or plane coordinate axes. Because they are used as a
framework for other surveys,these surveys must be precise and accurate.
horizontal; parallels or plane; precise and accurate - Answers Horizontal control surveys
coordinate________ positional data. These positions can be referenced by ______ or ______
coordinate axes. Because they are used as a framework for other surveys, these surveys must be
________ and __________.
Control by Traversing - Answers This procedure is generally less any expensive and can be extended
in direction. It can be undertaken even under less favorable weather conditions. However, its main
disadvantage is that there are fewer checks available when there is a need to locate surveying errors
and mistakes (Putt, 1990)
Control by Triangulation - Answers Triangulation surveys consist of networks of geometric figures
with almost all the angles measured directly in the field with relatively few of sides measured
(Putt,1990).
The positions of widely separated points are determined. The lengths and directions of the lines
joining these distant points also need to be determined. With triangulation more than one route can
be used in moving through the system to calculate desired lengths (Putt,1990).
Control by Trilateration - Answers In this procedure, the lengths of the sides of a series of triangles
are measured and the angles computed are from the lengths.Trilateration is the most accurate of the
three methods of establishing horizontal control because distances are measured more accurately
than angles (Putt,1990).
Just like triangulation, it has advantage that checks can be made in the calculations while moving
through the system by more than one possible route (Putt,1990).
Vertical Control Surveys - Answers is establishment of a network of reference bench marks.
Mine surveying - Answers is undertaken to support mining activities through provision of control
points for mining locations. These controls infrastructure construction and also for coordination are
used for of points within the mining areas.
Mine Surveying - Answers This type of surveying is more accurately undertaken than the other types
of survey and often involves use of more precise equipment.
Traversing and Leveling - Answers Methods of Establishing Controls in Underground Mining
Mean Sea Level and Geoid - Answers Vertical Controls
Traversing - Answers establishing of horizontal construction purposes or for delineating control
points are useful for feature boundaries, generation of topographic maps and also for detailed maps
for engineering works.
Link Traverse - Answers A closed route that starts from a known point and end at another known
point. It is geometrically open but mathematically close.
Loop Traverse - Answers If the traverse starts from a known point and closes at the same point, then
it is known as a _________ .
