Test Preparation on Civil Advance Surveying Part-1

1.

The angle between the direction of the star and the direction of the earth's axis of rotation is called

1Co-declination
2Co-latitude
3Declination
4Latitude

2.

Polaris is usually observed for the determination of the latitude when it is

1At culmination
2At elongation
3Neither at culmination nor at elongation
4Either at culmination or at elongation

3.

Pick up the correct statement from the following:

1The vertical plane containing the zenith, the station of observation and the celestial pole is the observer's meridian plane
2The angle between the direction of star in vertical plane and the direction of the star in horizontal plane is called the altitude of the star
3The complement of the altitude of star is called the zenith distance of the star
4All the above

4.

The point on the photograph where bisector between the vertical line through the optical center of the camera lens and the plate perpendicular meets is known as

1Principal point
2Isocenter
3Plumb point
4Perspective centre

5.

The station where observations are not made, but the angles at the station are used in triangulation series, is known as

1Satellite station
2Subsidiary station
3Pivot station
4Main station

6.

If the distance between the projectors is altered by a movement along X-axis of one projector

1The length of the air base is increased
2The scale of the model is altered
3y-parallax is not affected
4All the above

7.

On vertical photographs, height displacement is

1Positive for points above datum
2Negative for points below datum
3Zero for points vertically below the air station
4All the above

8.

At the first point of Aeries, the sun moves

1Northward
2Southward
3From south to north of the equator
4From north to south of the equator

9.

The difference in longitude of two places expressed in time is equal to the difference in their

1Sidereal time
2Apparent solar time
3Mean solar time
4All the above

10.

Pick up the in-correct statement from the following:

1Correction for refraction is always negative
2Correction for parallax is always positive
3Correction for semi-diameter is always negative
4Correction for dip is always negative
