The curvature of the Earth is taken into consideration if the limit of the survey is more than 250 km square

In order to determine the natural features such as Valleys, rivers, Lakes etc the serving is = topographical survey

the surveying it to determine additional details such as boundaries of field is called cadastral surveying

The fundamental principle of surveying is to work from the = whole to part

working from whole to part is done in surveying in order to ensure that = errors and Mistakes of one portion do not affect the remaining portion

the representative fraction 1/25000 means that the scale is 1 cm= 250

A plane scale is used to read = two dimensions

a scale which has a common representative fraction but read in different measures is called a = comparative scale

in a direct vernier the smallest division of vernier is………. the smallest division of its primary scale = shorter than

retrograde vernier the smallest division of vernier is……… the smallest division its primary scale = longer than

the instrument attached to the wheel of a vehicle in order to measure the distance travelled is = odometer

it is a more convenient and gives better results while measuring horizontal distance by escaping method = down the hill

the error in measure length due to incorrect holding of chain is = compensating error

direct ranging is possible only when the end  stations are = mutually intervisible

when the length of chain used in measuring distance is longer than the standard length the either in measure distance will be = negative error

if a chain is used at a temperature……. the temperature at which it was calibrated  the Easter in measured length is positive = lower than

if a chain is used at a temperature……….. the temperature at which was celebrated the error in measure length is negative = higher than

the positive error makes the measured distance……. the actual distance = more than

cumulative errors that occurs in chaining are proportional to = L

compensating errors that occur in chaining are proportional to = L

The tension at which the effects of Pull and sag for a tape are neutralized is known as = normal tension

A line  joining the apex of a triangle to some fixed point on the opposite side is called a = check line

A line joining some fixed point on the main survey lines called a = tie line

A baseline in Chain survey = fixes up the  direction of all others lines

in a well-conditioned triangle, no angle should be less than = 30 degree

A check line in a chain surveying = checks the accuracy of the framework

A Tie line in a chain surveying = enables the  surveyor to locate the interior details which are far away from the main chain lines.

The accuracy  in laying down the perpendicular offsets and in measuring them depends upon = scale of plotting, length of offset, importance of the object,

The limiting length of the offset is…….. when its perpendicular direction is set out by an eye = 15 m

the instrument used for setting out an offset at a right angle is called = open cross staff

the adjustable cross staff is used for setting out an offset = at any angle

an open cross staff is commonly used for setting out = long offset

The angle of intersection of the Horizon glass and index glass is an optical square is = 45 degree

The Horizon glass in an optical square is = half-silvered and half Unsilvered

The index glass in an optical square is = fully silvered

The optical square is used to measure angles by = reflection

In an optical square the angle between the first incident ray and the last reflected ray is = 90 degree

When the object lies on the left hand side of the chain line then while taking offset with an optical square it is held in = right hand upright

The angle between the reflecting surface of a Prism square is = 45 degree

The obstacles which obstruct vision but not chaining is a = hill

The obstacle which obstructs chaining but not vision is a = river

In a Prismatic compass the zero of the graduated ring is located at = south end

The true or Geographic Meridian through the various station = converge to the poles

The line in which the plane passing through the given point in the north and the South poles intersects the surface of the earth is called = true meridian

In a quadrantal system the bearing of a line is measured = clockwise or anticlockwise from the north or South which river is nearer the line towards east or West

The bearing observed with prismatic compass is…….. of a line = whole circle bearing

The horizontal angle between the true meridian and the survey line is called = azimuth

The horizontal angle between the true meridian and magnetic meridian is known as = magnetic declination

Due to the magnetic influence of the earth the magnetic needle of the Prismatic compass will be in client downward towards the pole this inclination of the needle with the horizontal is known as = dip

At the equator the amount of Dip is = 0 degree

At the magnetic poles the amount of dip is = 90°

The line of Earth’s magnetic field run from = north to south

The line passing through point at which the magnetic declination is equal at a given time are called = isogenic lines

The theodolite is an instrument used for measuring very accurately = horizontal and vertical angles

The process of turning the telescope of the theodolite over  its supporting axis through 180 in a vertical plane is called = transiting, reversing, plunging

An imaginary line joining the point of intersection of the cross hairs of the diaphragm and the optical center of the object class is known as = Land of collimation

A line joining the optical center of the object glass and the center of the eyepiece is known as = axis of telescope

The axis of telescope level must be……. to the line of collimation = parallel

In the surveying telescope cross hairs are fitted in = front of the eyepiece

In the surveying telescope diaphragm is held = nearer to the eye piece

The image formed by the objective in the plane of cross hairs is = real and inverted

The axis about which the telescope can be rotated in a horizontal plane is called = vertical axis

When the image formed by the objective is not situated in the plane of cross hairs = the object should be focused

When the crosshairs are not clearly visible = the eyepiece should be focused

The capacity of a telescope of producing a sharp image is called its = definition

An angle made by the survey line with the prolongation of the preceding line is known as = deflection angle

A deflection angle in a transverse is equal to the = difference between the included angle and 180

The deflection angle may have any value between = 0 degree and 180

An angle measured clockwise from the proceeding survey line to the following survey line is called a direct angles

The direct angles may have any value between = 0 degree and 360

when the angular and linear measurements are equally process in transverse in the balancing of a transverse is done by = bowditch’s rule

  when the angular measurements of a transverse are more precious than the linear measurement the balancing of a transverse is done by = transi rule

The method of Surveying used for determining the relative height of points on the surface of the earth is called = levelling

The line joining the points having the same elevation above the datum surface is called a = contour line

The contour interval depends upon the – nature of th ground, scale of map, purpose and extent of survey

The vertical distance between any two consecutive contours is called – contour interval

The contour interval throught the survey – should be constant

The contour lines can cross one another on map only in the case of – an overhanging cliff

Contours lines cross ridge or valley lines at – 90
