PDA를 활용한 지적측량기준점 조사 개선 방안에 관한 연구

Abstract

As the accuracy of the cadastral control points is related with the property rights of the citizens, their proper maintenance is required. As the cadastral surveying performs the basic operation of restoring boundaries on land registration maps and determines the same position repeatedly, the result of cadastral control point should be kept accurate. The government inspects the condition of cadastral control points annually in order to maintain the accuracy, however the limitations of the methods and the shortage of human resources make the inspection processes difficult. In order to solve the problems of current survey system, this study presents a method to use PDA with which they can survey the control points within the area under their charge anytime they want on the site. If the benefits earned from the suggested method in the study is computed using cost-benefit analysis, the following results are presented: the present value is 2.12 times after 15 years, the profit rate is 49.17% from 5-years ROI analysis, and pay-back period is 3 years.
