Abstract

Korea has established an advanced infrastructure for real-time precise positioning such as CORS, virtual reference station service and perform continuous upgrading. However, in order to utilize the national infrastructure, it is necessary to process the acquired spatial information and take many steps to derive the final product. In addition, this process is highly dependent on foreign software. In this study, GNSS field survey system was developed and evaluation of its usability was performed. Real-time GNSS field survey system was developed and the system improves user̓s convenience and usability. The system was able to conduct survey effectively and produce the results. In addition, we compare the existing software with the survey performance to show the availability of the real-time GNSS surveying system. The system developed through the research can perform all the functions from real-time survey to the production of the outputs. It can create economical added value of the foreign software as a whole and simplify the work required for post-survey performance.

우리나라는 국가 위성기준점 망, 가상기준점 서비스 운영 등 실시간 정밀위치결정을 위한 선진화된 인프라를 구축하고, 지속적으로 고도화해 나가고 있다. 하지만 국가적 인프라 활용에 있어 취득된 공간정보를 가공하여 최종 성과물 도출까지는 많은 과정을 거쳐야하며, 이 과정에서 외산 소프트웨어에 대한 의존성이 높은 편이다. 본 연구에서는 GNSS 측위 데이터 및 현장 측량시스템의 요구사항을 분석하여 실시간 정밀위치 결정과 효과적인 성과물 작성이 가능한 GNSS 현장 측량시스템을 개발하고 활용성을 평가하였다. 연구를 통해 사용자 편의성과 활용성을 향상시킨 실시간 GNSS 현장 측량시스템을 개발하였으며, 시스템을 이용하여 효과적으로 현황측량을 수행하고 성과물을 제작할 수 있었다. 또한 기존 측량시스템과 성과를 비교하여 개발된 GNSS 현장 측량시스템의 활용성을 제시하였다. 연구를 통해 개발된 시스템은 실시간 측량에서 성과물의 생성까지 일련의 기능을 모두 수행할 수 있으며, 외산 소프트웨어의 대체로 경제적 부가가치를 창출할 수 있어 측량업무의 효율성 향상에 기여할 것이다.
