地籍基準點의 管理改善을 위한 成果分析

Abstract

Cadastral ground control points(GCPs) have been required to support accurate cadastral surveying which provide basic location information in the terms of registration of the individual property, land taxation, geographic information and land use planning. In history, the Korean cadastral system was established by Japanese government through the Land and Forest Investigation Project during the colonial period. The original purpose of the project was not a development of national land but a acquisition of Korean land. This historical background has hindered the development of cadastral surveying technology and systematic cadastral GCPs management. During the Korean war, many of GCPs have been destroyed. Therefore the National Geography Institute initiated the national GCPs restoring project. However this project have carried out by private surveying companies under the contract out condition within limited time period. In the process of restoring GCPs, different degree of surveying accuracy was applied, even in some cases, the private surveying companies destroyed the existing GCPs intentionally to make a more profit. All these historical unsystematic management way of GCPs have affected with the accuracy of cadastral surveying which the original surveying results are essential elements to re-construct cadastral boundary. Most of all, in the process of restoring the destroyed GCPs, the difference of original surveying results have caused subsequent problems. The research objectives of this study are to access current status of cadastral GCPs unsystematic management ways focused on Kyeonggi province, highlight the importance of systematic cadastral GCPs management, the integration of separating GCPs managing departments and finally to present alternative in terms of improvement of maintenance and management cadastral GCPs.
