UAV를 이용한 지적재조사사업 경계설정 방식의 개선 연구

Abstract

In this study, we tried to analyze the type of the boundary demarcation for the existing cadastral resurvey project completion district and suggest a boundary demarcation method based on Actual-based land boundary using UAV. For districts that completed the project from 2012 to 2015, the actual-based land boundary reflection ratio is 69.4%, which is similar to the national average, but the actual land parcel area variation rate is 43.9%. In order to present the improvement, case area was selected and detailed boundary demarcation method was analyzed. As a result of the analysis, only 33% of the actual-based boundaries were determined as real boundaries, and the reflectance of actual-based boundaries was very low. In addition, as a result of the boundary demarcation analysis by the world geodetic coordinate transformation method, 216 cadastral non correspondence of the 1,929 parcels of which the coordinate conversion was completed were confirmed as the parcels. Therefore, based on the above analysis, this study proposed a method of installing a temporary boundary monument using UAV orthoimage as the boundary demarcation method based on the actual-based boundary using UAV.
