Total questions: 28
Worksheet time: 14mins
Foresights on a survey are always taken after backsights.
True
False
Most surveying elevations start at 100 feet to avoid negative numbers when measuring slope.
True
False
A station in a survey may have a foresight and no backsight.
True
False
To get the station elevation, subtract the backsight from the height of instrument.
True
False
When completing field notes, column headings are not necessary, as all surveyors follow the same format.
True
False
To calculate the height of instrument, add the backsight measurement to the elevation.
True
False
The longer the distance of the traverse, the greater the allowable error.
True
False
Most surveys assume a starting benchmark elevation of 100 feet.
True
False
During a profile survey, there is never the need for a turning point because all of the readings may be taken from one level or transit location.
True
False
Which tools are commonly used to measure long distances when surveying?
chaining ring and pins
hand sighting caliper
surveyor's scale
tape measure
In surveying, how should 6 inches be noted?
1/2 ft
0.05 ft
0.5 ft
0.6 ft
Who on a taping crew has the responsibility of taking the zero end of the tape and advancing in the direction of the line to be measured, pulling the tape behind?
head tape person
note keeper
rear tape person
secondary tape person

backsight
height of instrument
foresight
turning point
A solid location, usually marked by a temporary stake, on which a foresight is taken, to which the instrument is moved, and from which a backsight is taken to determine a new height of instrument.
