A COMPARATIVE STUDY OF CONVENTIONAL SURVEYING TECHNIQUES WITH TOTAL STATION AND GPS

Today advanced Surveying techniques are improving accuracy of measurements of distance, height, area and positional information of an area. Total station is an advanced instrument which is mainly used for measuring horizontal distance, slope distance, remote objects height and area of a land parcel now a days this instrument is majorly used for determining the land area information. The objectives of this thesis is to evaluate and compare accuracy and time expenditure of conventional methods like Chain, Tape, Plane Table and Theodolite with Total Station (TS) and Global positioning system (GPS).by Comparing the accuracy and the required time of these measurements will improve the knowledge about how much the precision and accuracy can be achieved by advanced instruments and at which time expense. It is possible to conduct survey with less man power and less time while using Total station. In the Campus of Karpagam Academy of Higher Education (KAHE) football ground was taken as study area. The aim of the study is to compare the land survey results conducted by conventional methods with Total Station and GPS. The study area was measured using conventional methods like Chain, Tape, Plane Table and theodolite Total Station (TS) and Global positioning system (GPS). The collected data was processed in AUTO CAD and terrasync. The results were compared and analyzed. The campus will be measured using total station. Finally the plots are represented separately with the scale and area information.
