Surveying Questions

• The branch of surveying in which both horizontal and vertical positions of a point, are determined by making instrumental observations, is known
• The latitude of a traverse leg is obtained by multiplying its length by
• Probable systematic error in precise levelling as recommended by International Geodetic Association should not exceed (where k is in kilometers.)
• If the rate of gain of radial acceleration is 0.3 m per sec3 and full centrifugal ratio is developed. On the curve the ratio of the length of the transition curve of same radius on road and railway, is
• True meridian of different places
• For setting out a simple curve, using two theodolites.
• Orientation of a plane table by solving two point problem is only adopted when
• Measuring with a 30 m chain, 0.01 m too short, introduces
• A uniform slope was measured by the method of stepping. If the difference in level between two points is 1.8 m and the slope distance between them is 15 m, the error is approximately equal to
• Keeping the instrument height as 1 m, length of staff 4 m, the up gradient of the ground 1 in 10, the sight on the up slope must be less than
• For a curve of radius 100 m and normal chord 10 m, the Rankine's deflection angle, is
• If the area calculated form the plan plotted with measurements by an erroneous chain, accurate area of the plan is
• It θ is the probable error of an observed bearing of a line of length l, the error over the whole length of the traverse of n lines of length l is
• Metric chains are generally available in
• Two hill tops A and B 20 km apart are intervened by a third top C. If the top most contour of the three hill tops are of the same value, state whether the line of sight AB
• If the angular measurements of a traverse are more precise than its linear measurements, balancing of the traverse, is done by
