Abstract

Technologies that are leading the fourth industrial revolution, such as the Internet of Things (IoT), big data, artificial intelligence (AI), and cyber-physical systems (CPS) are developing and generalizing. The demand to improve productivity, economy, safety, etc., is spreading in various industrial fields by applying these technologies. Digital twins are attracting attention as an important technology trend to meet demands and is one of the top 10 tasks of the Korean version of the New Deal. In this study, papers, magazines, reports, and other literature were searched using Google. In order to investigate the contribution or role of geospatial information in the digital twin application, the definition of a digital twin, we investigated technology trends of domestic and foreign companies; the components of digital twins required in manufacturing, plants, and smart cities; and the core techniques for driving a digital twin. In addition, the contributing contents of geospatial information were summarized by searching for a sentence or word linked between geospatial-related keywords (i.e., Geospatial Information, Geospatial data, Location, Map, and Geodata and Digital Twin). As a result of the survey, Geospatial information is not only providing a role as a medium connecting objects, things, people, processes, data, and products, but also providing reliable decision-making support, linkage fusion, location information provision, and frameworks. It was found that it can contribute to maximizing the value of utilization of digital twins.

사물인터넷(IoT), 빅데이터(Big data), 인공지능(AI), 사이버물리시스템(CPS) 등 4차 산업혁명을 견인하는 기술들이 발전/보편화되고 있다. 이 기술들을 응용하여 다양한 산업 현장에서 생산성, 경제성, 안전성 등을 향상하고자 하는 요구가 확산되고 있다. 디지털트윈은 이러한 요구를 충족시키기 위한 중요한 기술 트렌드로서, 그리고 한국판 뉴딜의 10 대 과제 중 하나로 주목 받고 있다. 본 연구에서 구글 웹 검색기를 사용하여 논문, 매거진, 보고서, 기타 문헌을 탐색하였다. 디지털트윈 응용분야에서 공간정보의 기여 내용(또는 역할)을 조사하기 위해 디지털트윈의 정의·국내외 기업별 기술동향, 제조업·플랜트·스마트시티에서 요구되는 디지털트윈의 구성 요소와 디지털트윈 구동을 위한 핵심기술을 조사하였다. 그리고 공간 관련 키워드인 Geospatial Information, Geospatial data, Location, Map, Geodata와 디지털 트윈 간 연계 문장이나 낱말을 탐색하여 공간정보의 기여내용을 정리하였다. 조사 결과, 공간정보는 단순히 사물-사물-사람-프로세스-데이터-제품을 연결하는 매개체로서의 역할 제공뿐만 아니라 신뢰성 높은 의사결정지원·연계융합·위치정보제공·프레임워크 등의 역할을 수행함으로 디지털트윈의 활용 가치 극대화에 기여할 수 있을 것으로 나타났다.
