The purpose of this study is to search accurate and efficient register method the cadastral control point of island which are many unregistered area in the cadastral records as the accurate position using the GPS Continuous station data.
Nothing is more important than accurate position registration of unregistered islands for the accurate management of national territory and development of islands, to achieve this purpose must performed accurate survey of cadastral control point in the first place.
However, it is difficult to guarantee the advantages of GPS, and also, discrepancies between applicable island area and neighboring area are expected under the condition of only using the current survey cadastral control point showing the errors upon survey of cadastral control point using the GPS.
Therefore, we have studied the plan of measurement the cadastral control point of island area as the accurate position by comparing and analyzing the accomplishment resulted from the coordinate transformation and calculation method using the existing registration coordinate and accomplishment resulted from the trivariant net coordination and calculation method in this study. The results of this study are as follows:
We check the difference between accomplishments resulted from two methods by calculating the cadastral control point accomplishment resulted from the coordinate transformation and calculation method using the existing registration accomplishment and cadastral control point accomplishment resulted from the trivariant net coordination and calculation method using the GPS Continuous station data. Also, we see that the accomplishment differs according to number of continuous stations fixed upon trivariant net coordination and calculated accomplishment differs according to distance between continuous station and island area. We coordinate and calculate the trivariant net based on the continuous station data against the accomplishment resulted from the coordinate transformation.
