*Principle of surveying is to prevent accumulation of errors is

• to work from whole to part

• to work from part to whole

• both (A) & (B) above

• non of above

Under survey " working from whole to part" is done

• to prevent the accumulation of error

• to localise the error

• both of above

• non of above

*The curvature of the earth's surface is taken into account only if the extent of survey is more than

• 60 sq km

• 160 sq km

• 260 sq km

• 500 sq km

• Geodetic survey is different from plane surveying because of

• very large area is covered

• the curvature of the earth is considered

• undulation of the topography

• the large difference of elevation

Hydro-graphic survey deals with the mapping of

• large water bodies

• canal system

• cloud movement

• non of the above

The survey which is carried out for determining absolute locations & the direction of any line on the surface of the earth by making observation to heavenly bodies is called

• Hydro graphic survey

• astronomical survey

• land survey

• non og above

The scale representing either three units or only one unit & its fractions upto second place of decimal point is

• diagonal scale

• comparative scale

• simple vernier

• shrunk scale

The scale used to measured & to set out the angle is

• diagonal scale

• comparative scale

• vernier scale

• scale of chords

Which the following scale is the smallest one

• 1 cm= 10 m

• 1 cm = 100 m

• 1 cm = 1000 m

• 1 cm = 10000 m

The types of error which are of cumulative nature & can be corrected is known as

• permissible error

• residual error

• expected error

• systematic error
