Solve Any One of the following.
a) De?ne i) Veitical circle ii) The Prime Vertical iii) The Longitude iv) The
Latitude v) The Declination vi) Hour Circle .
b) Explain method of determination of latitude by meridian altitude of Sun or Star
with neat labeled diagram.
The meridian altitude of the Sun?s lower limb was observed to be 41?12?26? at a
place in longitude 72?20?45? W to determine the latitude of the place. The Sun
was to the south of the zenith. The declination of the sun at GAN on the day of
observation was 19?38?52? N, increasing 7.46? per hour and in semi?diameter
16?14?24?. Determine the Latitude of the place.
Solve Any Two of the following.
De?ne Combined Curve. Explain elements of Combined curve with neat labeled
diagram.
Calculate the RL of the various pegs on a vertical cuwe connecting two grades of
+0.6% and -O.6%. The chainage and the RL of intersection point are 550 and
325.50 m respectively. The rate of change of grade is 0.1% per 30 m.
What is Shift? Prove that a transition curve bisects a shift and that a shift bisects
a Transition Curve.
Solve Any Two of the following.
a)Two points A and B having elevations of 500m and 300 m respectively above
datum appear on the vertical photograph having focal length of 20cm and ?ying
altitude of 2500111 above datum. Their correlated photographic co?ordinates are
as follows:

b) It is required to do photogrammetric survey over an area of 500 sq.km, scale
of photograph 1 in 10000 and photograph format is 230mm X 230mm. Taking
longitudinal overlap 60% and side overlap 30%. Calculate the number of
photographs required.
a) A line AB measures 11cm on a photograph taken with a camera having focal
length of 21.5cm. The same line measures 3 cm on a map drawn to a scale of
1/45000. If the average altitude is 350 m, Calculate the ?ying height of the
aircraft.
b) A line 2350 m long lying at an elevation of 500m measure 10.50 cm on a
vertical photograph. The focal length of the camera is 20cm. If the elevation of a
point is 1200m. Calculate the scale of photograph.
