Utilizing Spatial-data to Provide for U-Service Based on U-GIS

  • Published : 2009.12.31

Abstract

According to the changes of the city's paradigm, the demand on u-City increases rapidly. u-City has been built at 54 areas in Korea (as of May 2009). One of the important determinants of success or failure in the increasing of u-City is how to provide u-Services. Most current u-Services are Sensor Network-based monitoring services to manage urban infrastructure. u-GIS is one of fundamental requirements to implement 'any time and any where' u-Service which covers the essential meaningful term "ubiquitous". Hence, in this paper, we 1) describe the definition of the spatial awareness, 2) discuss how to converge (Spatial Embedding) among different spatial data : topographic spatial data, sensor spatial data, and more, 3) bring forth an advanced form of u-Service, 4) analyze the state-of-the-art u-GIS techniques.

도시의 패러다임이 변화하고 이에 따라 u-City의 수요가 급증하고 있다. 우리나라에서만 2009년 5월을 기준으로 54개 지역에서 u-City가 구축되고 있다. 이렇게 급증하는 u-City의 성패를 좌우하는 중요 요소 중 하나가 바로 u-City에서 제공하고자 하는 u-서비스라고 할 수 있겠다. 현재의 u-서비스는 센서네트워크를 기반으로 하는 도시 관리 위주의 모니터링 서비스가 대부분이다. 유비쿼터스의 본질적 의미인 '언제 어디서나'의 u-서비스를 구현하기 위해서는 공간정보의 활용이 필수적이다. 공간정보와 센서정보의 결합은 공간인지(spatial awareness) 를 가능케 하여, 모니터링서비스에서 보다 나아가 공간분석이 가능한 서비스로의 발전을 도모할 수 있다. 따라서 본 연구에서는 1) u-서비스에서 spatial awareness는 어떤 의미 인지를 명확히 하고, 2) spatial awareness를 가능케 하기 위해 공간정보, 센서정보, 기타 정보들이 어떻게 융합 (Spatial Embedding) 되어야 하는지 논하고, 3) U-GIS를 기반으로 한 u-서비스 시나리오 4가지를 제안하고, 4) 현재의 기술개발 현황에 대해 분석해 보고자 한다.
