지적세부측량에 있어서 RTK-GPS의 활용 방안

RTK-GPS를 활용한 지적세부측량의 적용 방안을 연구했다.

To survey a land by using RTK-GPS in a wide field can be somewhat expected the accuracy and efficiency. Nevertheless, we can not adopt it in a cadastral surveying field because statutory guidelines have not prepared. In fact, we can not deny that it is unsuitable in a densely built-up area because the satellite reception is not clear. That is the main reason why we have not been able to use the method in surveying a land parcel. In this context, this study intended to examine problems occurred in adopting a RTK-GPS in a field and to propose plans that we can use it in a cadastral surveying field.

If there is no difference between an existing result and new one which surveyed though other Reference Stations it is perfectly possible for a surveyor to save expense and time. Therefore, I tried to prove it after a control experiment. Firstly, I choose the 120 points in the specific area and surveyed with the method of RTK-GPS. Then I compared the new results with the existing one. After the analysis, I could recognized that it did not make a scrap of difference. As a result, we can examine an accuracy of the result without repeated survey when we select other Reference Stations.

In conclusion, this study proposed that (ⅰ) the act for practical use of RTK-GPS in a cadastral field should be prepared, (ⅱ) the RTK-GPS has to be closely connected with the existing surveying method(i.g., Total Station), (ⅲ) the method of Network RTK needs to be introduced to improve accuracy of Reference Stations, (ⅳ) the GPS, GLONASS and Galileo satellite should be unified in order to guarantee a stability of surveying outcomes.
