Question 1
Cross staff survey is used to
Question 2
An area of a field is 300 square centimeters from a shrunk map having shrunk factor of a 0.8 . Calculate the original area (square meters) on the field, if the original scale of the map is 1 cm = 50 m.
Question 3
On an old map, a line was drawn to a magnetic bearing of 10
30’, the magnetic declination being 2
east at that time. The magnetic bearing to which the line should be set now if the present magnetic declination is 4
30’ west
30’, the magnetic declination being 2 east at that time. The magnetic bearing to which the line should be set now if the present magnetic declination is 430’ westQuestion 4
The following readings were taken during a compass survey in Allahabad. Find the corrected forebearing of BC.
Question 5
In a badly maintained field book, following observations were found
Bearing of line AB with true north = 123 °
Acute angle ABC = 82 °
When extended line BC is rotated by an angle of 30 ° (clockwise), it meets the line CD.
If the bearing of line DC with true North is more than 180 °, then its bearing value (in degrees) is
