Document Summary
Basic principle of plane table surveying 5. References (i) bannister, a and raymond, s (1998, 7th ed). Surveying, elbs.

In this method of surveying, field observation and plotting are done simultaneously helping the surveyor to compare the plotted details with actual features of the ground. This method of survey requires no field book. A plane table mounted on a tripod stand and a number of accessories are used during plane table survey. The accessories consist of alidade, spirit level, trough compass, plumbing fork, plumb bob, drawing sheet. The plane table consists of a drawing board with arrangement for fixing on a tripod stand.
