Plane Table Surveying

In this method of surveying a table top, alike to drawing board fitted on to a tripod is the major instrument. On to the table top a drawing sheet is fixed, the observations are made to objects, distances are scaled down and the objects are plotted in the field itself. There is no possibility of omitting any necessary measurement in this surveying as the plotting is made in the field itself. However the accurateness achieved in this type of surveying is less. Therefore this type of surveying is utilized for filling up details between the various survey stations earlier fixed by other methods.
