V SEMESTER B.TECH DEGREE EXAMINATION(S), MAY 2019

Course Code: CE307
Course Name: GEOMATICS

PARTA

Answer any two full questions, each carries 15 marks.
Explain successive bisection of chord method to set out simple circular curve.
Explain error of closure with the help of a sketch. In a traversing, latitude and
departure of the sides were calculated and it was observed that Llatitude = 1.39
m and Departure = -2.17 ൩. Calculate the length of the closing error and its
orientation.
Two tangents intersect at chainage 60 chain + 60 links, the deflection angle
being 52°30’. Calculate the necessary data for setting out a curve of 20 chains
radius to connect the two tangents if it is intended to set out the curve by
ordinate from long chords. Take peg interval equals to 20 m and length of chain
as 20 metres.
Explain elements of a compound curve with a neat sketch.
While making a traverse survey, a surveyor started from point A, walked 1000m
in 5 67° W and reached point 8. Then he changed his direction and walked 512
m in 1410 ° 8 and reached point C. Then again he changed his direction and
walked 1504 m in S 65 ° E and reached point D. Now the surveyor wants to
return to A. Which direction should he move in and how many meters?

Explain consecutive co-ordinates and independent co-ordinates.

PART छ
