Plane table surveying involves simultaneously conducting field work and plotting measurements on a plane table. It uses accessories like a plane table, alidade, compass, and tripod to take measurements via methods such as radiation, intersection, and resection. Plane table surveying is used to map details between fixed points determined by other methods, in magnetic or industrial areas, and for small-scale maps. Potential errors include instrumental errors and errors in sighting or plotting. Advantages are low cost, rapid work, and elimination of field notes, while disadvantages include unsuitability for large scales, accuracy, or wooded areas.

PLANE TABLE SURVEYING Plane table is a graphical method of surveying in which the field work and the plotting is done simultaneously.. It is very simple method .. It is a conventional instrument..
ACCESSORIES Plane table Alidade Compass Level tube U-frame Plumbing fork Plane paper Tripod Pin Screws
METHODS OF PLANE TABLE Radiation method Intersection method Traversing method Resection method
APPLICATIONS Plane table is used in surveying and related disciplines to provide a solid and level surface on which to make field drawings,charts and maps. It is used to fill in details between station fixed by triangulation method or theodolite traversing method. Magnetic areas. Industrial areas.
ERRORS IN PLANE TABLING The common sources of error may be classified as : Instrumental errors Errors of manipulation and sighting Errors of plotting
ADVANTAGES It is one of the most rapid method of surveying. It is less costly than theodolite survey. It is most suitable for small scale map. Field notes are not required and thus the possibility of mistakes in booking is eliminated. It is particularly suitable for filling in details in hilly areas and in magnetic areas where chain and compass surveys are not suitable.
DISADVANTAGES It is not suitable in monsoon and high wind. It is not suitable for large scale surveys and accurate work. It is not suitable for surveying a densely wooded area. Due to heaviness, it is inconvenient to transport. The absence of field notes is sometimes inconvenient if the survey has to be replotted to a different scale.
