Cadastral surveying is related to demarcating legal boundaries and areas for the sake of registering a property on cadastral records or restoring registered boundaries on the ground. It is composed of control surveying (cadastral triangulation and supplementary control surveying) and detail surveying. Detail surveying is classified into plane table surveying by graphical cadastral map and numerical surveying by boundary point coordinates. In this study we compared the accuracy of plane table surveying with numerical surveying using Parcel Based Land Information System(PBLIS) data constructed by the cadastral map digitalization business.

In conclusion, the result by numerical surveying was analyzed as more accurate than the result of plane table surveying, as Root Mean Square Errors(RMSE) of graphical cadastral surveying is 0.766m and that of numerical cadastral surveying using Total Station(T/S) is 0.683m. Therefore, PBLIS data is expected to be used for surveying legal boundaries and areas in the near future.
