Question
A survey party preceded to do their stadia survey work as follows:
The transit was set-up at point A with the line of sight horizontal rod readings were taken on rod at points B and
C, which were then measured and have taped distances from A to 200m and 60m respectively. Stadia
Intercept at Rod B and Rod C were observed as 2.001m and 0.600m respectively. The stadia constant was
recorded as 0.30m.
They went on to survey other points with the transit at point D, two points E and F were sighted and the data
was recorded as follows:
Stadia Intercept
Vertical Angle
Rod E
2.120m
+04°22"
Rod F
3.560m
-03°17
1. Compute the Stadia Interval Factor.
2. Compute the horizontal distance EF.
3. Compute the difference in elevation between points E and F.

Elevation of three hills was recorded as per below tabulation.
STATIONS
ELEVATION
ALPHA (1+052)
680m
BRAVO (13+052)
645m
CHARLIE (28+052)
620m
1. Compute the elevation of line of sight at Station Bravo with the instrument placed at Station Alpha such that
Station Charlie would be visible from Station Alpha.
2. Assuming that Station Bravo will obstruct the line of sight from Station Alpha while observing Station Charlie
and a 4m tower was constructed on top of Station Bravo. Compute the height of equal towers to be
constructed at Station Alpha and Station Charlie in order that both three stations are visible with each other.
3. Without constructing any tower at station Bravo, what height of tower must be constructed at Station Charlie
so that both Station Bravo and Charlie would be visible from Station Alpha?
