Abstract

The high popularity of geo-referenced mash-up improves the quality and availability of geo-referenced contents. Such contents which accurately represent the real world in street level as well as in aerial level have appeared. Despite the advent of geo-referenced contents of street level, it is still hardly used for mash-up. In this study, we thus find out its obstacles to spatial mash-up and solutions to overcome them to activate the mash-up based on street level contents. By analyzing the current geo-referenced content with respect to its spatial scope and the way of representation, we draw the limitations of current street level contents. Furthermore, we propose the 'new media geo-referenced content' as a solution to overcome those limitations. With 'new media geo-referenced content', it is able to determine the 3D coordinates of given object in real world. Using those coordinates, database linkage can be more closer, flexible and organic. Such 'new media geo-referenced content' can contribute to activation of geo-referenced contents in street level and its mash-up.

공간정보를 기반으로 다양한 주제의 매쉬업(mash-up)이 활발해지면서 공간정보 콘텐츠의 품질과 활용성이 높아지고 있다. 항공 수준에서 시작해서 거리 수준의 실외와 실내 공간까지도 실제처럼 표현한 공간정보 콘텐츠들이 등장하였다. 그럼에도 불구하고 거리 수준의 공간정보 콘텐츠를 기반으로 한 매쉬업 사례는 상당히 미진한 상황이다. 본 연구에서는 거리 수준 콘텐츠의 활성화를 위해 기존 거리 수준의 공간정보 콘텐츠가 가진 한계를 도출하고, 이를 극복하기 위한 방안을 모색하고자 한다. 기존의 공간정보 콘텐츠를 공간적 범주와 표현 방법에 따라 분류하여 각 특성에 따라 현황을 분석하고, 이를 통해 기존 거리 수준 공간정보 콘텐츠의 한계를 도출한다. 나아가 기존 거리 수준 콘텐츠의 한계를 극복하기 위한 방안으로 '뉴미디어 공간정보 콘텐츠'를 제안한다. '뉴미디어 공간정보 콘텐츠'는 콘텐츠 내에서 객체의 3차원 지상 좌표를 결정할 수 있고 그 좌표를 매개로 데이터베이스와 유기적으로 연동될 수 있다. 지상의 절대 좌표를 참조 키로 하는 '뉴미디어 공간정보 콘텐츠'는 다양한 정보와의 정교하고 유기적인 연동을 실현하고, 이를 통해 거리수준 콘텐츠의 활성화에 기여할 것이다.
