Surveying & Transportation Engineering Flashcards
is the technique, profession, art and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.

Surveying
Most instruments screw onto a ____ when in use.
Tripod
____________ are often used for measurement of smaller distances.
Tape measures
___________ and various forms of ______ imagery are also used.
3D scanners - aerial
is an instrument for the measurement of angles.
Theodolite
It uses two separate circles, protractors or alidades to measure angles in the horizontal and the vertical plane.
Theodolite
is a form of theodolite that uses a gyroscope to orient itself in the absence of reference marks.
Gyro theodolite
It is used in underground applications.
Gyro theodolite
is a development of the theodolite with an electronic distance measurement device (EDM).
Total station
can be used for leveling when set to the horizontal plane.
Total station
used to mark points prior to marking pins and for the surveyor to see those points with theodolite / total station through a distance.
Staging rod or range pole
Staging rod is also called?
Range pole
Used as the base of the equipment for stability and ensure that it is levelled through the bubble.
Tripod
Used to mark points on the actual layout on the ground after measurements and levels are established.
Marking pins
Used to measure elevation readings through theodolite / total station.
Stadia rod
topographic, layout, and as-built surveys associated with engineering design.
Engineering survey
They often need geodetic computations beyond normal civil engineering practice.
Engineering survey
a survey that documents the location of recently constructed elements of a construction project.
As-built surveying
is also known as a ‘works as executed survey’.
As-built survey
are done for record, completion evaluation and payment purposes.
As-built surveys
are often presented in red or redline and laid over existing plans for comparison with design information.
