ne of sight horizontal, took rod reading at points B and C which is 300m and 80m from A respectively. With rod at B, the stadia interval was recorded to be 3.001m and with the rod at C, the stadia interval was recorded to be 0.800m. The distance from the instrument to the principal focus was recorded to be 0.30m. Then they went to survey other points with some of the data recorded as follows with the transit at point D, the two points E and F were sighted. Rod at E Stadia interval = 2.25m
A
at A and with the line of sight horizontal, took rod reading at points B and C which is 300m
and 80m from A respectively. With rod at B, the stadia interval was recorded to be 3.001m
and with the rod at C, the stadia interval was recorded to be 0.800m. The distance from
the instrument to the principal focus was recorded to be 0.30m. Then they went to survey
other points with some of the data recorded as follows with the transit at point D, the
two points E and F were sighted.
Rod at E Stadia interval = 2.25m
Vertical Angle = +4030’
Rod at F Stadia interval = 3.56m
Vertical Angle = -3
030’
a. Compute the stadia interval factor
b. Compute the horizontal distance DE
c. Compute the difference in elevation between E and F assuming elevation of D is
350.42m above sea level.
