Surveying and Levelling Set 1

Chain surveying is well adopted for

• Small areas in open ground

• Small areas with crowded details

• Large areas with simple details

• Large areas with difficult details

Surveys which are carried out to provide a national grid of control for preparation of accurate maps of large areas are known

• Plane surveys

• Geodetic surveys

• Geographical surveys

• Topographical surveys

A relatively fixed point of known elevation above datum, is called

• Bench mark

• Datum point

•  Reduced level

• Reference point

Traverse in a surveying is...

• a disconnected survey line

• a series of connected survey lines

• any survey line joining two main stations

• Can't say

Identify the type of traverse shown in the figure

• Closed Traverse

• Open Traverse

• Can't Say

The bearing of a survey line observed with reference to a magnetic meridian is called as

• Arbitrary Bearing

• True Bearing

• Magnetic Bearing

If a survey line is named as 'AB', then the bearing observed at station B looking towards station A is called as '

• Forward Bearing

• Backword Bearing

• Bearing

In a Whole Circle Bearing System (WCB), the bearings are ranging between

• 0-360 degrees

• 0-180 degrees

• 0-90 degrees

• 0-270 degrees

In a quadrantal bearing system (QB), the bearings are ranging between

• 0-360 degrees

• 0-270 degrees

• 0-180 degrees

• 0-90 degrees

Meridian in surveying is...

• a reference direction with respect to which the direction of lines is mentioned.

• always a reference direction shown by magnetic compass

• a reference direction with respect to which the direction of lines is not mentioned.

• always an arbitrarily chosen reference direction with respect to which the direction of lines is mentioned.
