Abstract

Globally, mobile, cloud computing or big data are the recent marketable key terms. These trend technologies or paradigm in the ICT (Information Communication Technology) fields exert large influence on the most application fields including geo-spatial applications. Among them, cloud computing, though the early stage in Korea now, plays a important role as a platform for other trend technologies uses. Especially, mobile cloud, an integrated platform with mobile device and cloud computing can be considered as a good solution to overcome well known limitations of mobile applications and to provide more information processing functionalities to mobile users. This work is a case study to design and implement the mobile application system for geo-spatial image filtering processing operated on mobile cloud platform built using OpenStack and various open sources. Filtering processing is carried out using R environment, recently being recognized as one of big data analysis technologies. This approach is expected to be an element linking geo-spatial information for new service model development and the geo-spatial analysis service development using R.

정보통신기술(ICT: Information Communication Technology) 분야의 시장을 주도하는 모바일, 클라우드 컴퓨팅, 빅데이터 등과 같은 트렌드 기술들은 공간정보 분야를 포함한 대부분의 응용분야에 지대한 영향을 미치고 있다. 이중에서 클라우드 컴퓨팅은 비록 우리나라에서는 초기 적용단계 수준이지만 다른 트렌드 기술들 간의 연계를 위한 플랫폼 역할을 담당한다. 특히 모바일과 클라우드 컴퓨팅이 결합된 형태인 모바일 클라우드는 모바일 단말 환경의 제한점들을 보완하고 기존의 모바일 앱에 비하여 더 많은 정보처리기능의 제공이 가능하다는 점에서 주목을 받고 있다. 이번 연구에서는 모바일 클라우드 환경을 OpenStack 및 다양한 오픈소스를 활용하여 구축하고, 이를 플랫폼으로 하여 공간영상정보 필터링 기능을 수행하는 시스템을 시험적으로 설계 및 구현하였다. 한편 공간영상정보 처리는 빅데이터 분석기술로 각광받고 있는 R 환경을 적용하여 필터링 처리를 수행하였다. 이러한 시도는 향후 R을 활용한 공간영상정보 분석서비스 개발과 다양한 공간정보와 연계되는 새로운 서비스 모델 개발에 적용될 것으로 기대한다.
