Abstract
The object of this study is to verify the feasibility in the application of the GPS system data to the existing geodetic and cadastral survey system. WGS-84 data, which were converted into domestic geometric coordinate system, were compared with those of the existing triangular coordinate system in Gwangju area. The significant results in this study are summarized below ; GPS system is more speedy and accurate than the existing triangular coordinate system in the survey of points in triangular coordinate or on the map. And the error in the GPS system was more uniform than that of the existing triangular coordinate system. GPS system is more effective than the existing triangular coordinate system in the future geodetic and cadastral survey because GPS data can be processed by the computer. It is necessary to calculate the conversion coefficients to apply GPS data practically to the existing geodetic and cadastral survey system. It can be achieved by the individual investigation on how the existing data in the domestic coordinate system were determined.
