정밀지적측량을 위한 전북지역 GPS변환계수 결정에 관한 연구

정밀 지적측량을 위한 전북지역 GPS 변환계수를 결정했다.

The GPS (Global Positioning System) survey method being used throughout the whole society such as surveying, transportation, traffic, communication, leisure etc., as well as the recent military purpose has been used commonly from the late in the 90's after it had been introduced from the middle in the 90's. The method of late handling by the Static Survey being used generally in the present cadastral survey has been used widely. However, the outcome of Unknown site may be determined by the degree of accuracy of the near Known triangular point so that it causes to decrease the efficiency of work and to express a variety of problems.

In particular, a method to determinate the outcome using the control point of small areas has been used so that it is difficult to decide the outcome for the adjacent part between areas, and the unbalance of joining between areas occursby reason that the unified outcome can not be provided so that the non-conformity of wide range of areas resulted from GPS survey has been arising now.

Therefore, in order to solve this issue, the non-conformity between areas may be solved by enforcing the GPS synchronous survey for general triangular point (usually the first, the second class triangular point preoccupation) of Jeonbuk province, and computing the Local Transformation Parameter covering all the area of the Jeonbuk province, and analyzing the differences with the outcome of existing survey as the cadastral survey using this is used so that it could solve the non-conformity between areas and provide the regular acreage outcome at all times, then it takes aim at using the land effectively and protecting the individual proprietary rights.

As a result of analyzing the conformity for each area using the parameter value of Jeongbuk areas, that of Jeonju area have shown within about 8~15cm, Jeongeup one within about 10~12cm, Buan one within about 19~35cm and Sunchang one within about 30~44 cm. Consequently, it is determined that the Jeonju and Jeongeup area can be made it practicable, and a little adjustment will be required in the Jeongeup area, finally the extra parameter will be required in the Sunchang area. Besides, as a consequence of the outcome analysis for traverse surveying with regard to the west of a new section of a city, R.M.S.

comes under within 13~15cm and the outcome approval error of cadastral survey is included in the 15cm of outcome approval error so that it was determined that the traverse surveying can be done.
