Advantages and disadvantages of plane table surveying

1.Advantages of plane table surveying

  1. The plain is drawn by the outdoor surveyor himself while the country is before his eyes and therefore there is no possibility of omitting the necessary measurements
  2. The surveyor can compare plotted work with the actual features of the area.
  3. Since the area is in view, contour and irregular objects ma be represented accurately.
  4. Direct measurements may be almost entirely dispensed with, as the linear and angular dimensions are both to be obtained by graphical means.
  5. Notes of measurements are seldom required and the possibility of mistakes in looking is eliminated.
  6. It is particularly useful in magnetic areas where the compass may not be used.
  7. It is simple and hence cheaper than the theodolite or any other type of survey.
  8. It is most suitable for small scale maps
  9. No great skill is required to produce a satisfactory map and the work may be entrusted to a subordinate.

2.Disadvantages of plane table surveying

  1. The plane table is not intended for very accurate work.
  2. It is essentially a tropical instrument
  3. It is most inconvenient in the rainy season and in a wet climate
  4. Due to heaviness, it is inconvenient to transport.
  5. Since there are so many accessories, there is every likelihood of these being lost
