Surveying - Engineering

Q1:

Pick up the method of surveying in which field observations and plotting proceed simultaneously from the following

A chain surveying

B compass surveying

C plan table surveying

D tacheometric surveying.

ANS:C - plan table surveying

Because in Plane Table survey both fieldwork and office work are done simultaneously while doing the survey. No need to record the readings and workout it in the office. Chain surveying- linear measurements.
Compass surveying - only angular measurements.
Tacheometry- both measurements.
