Abstract

Map rendering, positioning, database managements are key elements of location based services. Google map and GPS (Global Positioning System) have become a very popular solution for map rendering and positioning, respectively. They are very effective and yet free of charge. However, they cannot be used for an indoor location based service system. We cannot render a building drawing with Google map, we cannot determine a moving object's position when it is indoor. This paper introduces our web services of rendering drawings, indoor positioning, and multimedia contents up-loading and playing so that any programmers can use them in developing indoor location based service systems. In order to experimentally show the efficiency of our web services, we have built a location based contents displaying system for museum visitors with them.

위치기반서비스 시스템의 주요 컴포넌트에는 도면출력, 측위, 데이터베이스 관리 등이 포함된다. 도면출력은 일반적으로 구글 지도를 사용하며 측위는 GPS(Global Positioning System)를 사용한다. 그러나 위치기반서비스를 옥내에서 구현하려면 이러한 일반적인 솔루션을 사용할 수가 없다. 즉, 구글 지도로 건물 내부 도면을 출력할 수도 없고, GPS로 건물 내부의 이동객체의 위치를 측정할 수도 없다. 본 연구는 도면출력 기능, 옥내측위 기능 그리고 데이터베이스에 콘텐츠 업로드 및 출력 기능들을 웹서비스로 구현한 사례를 소개하여, 프로그램 개발자가 누구나 쉽게 호출하여 사용할 수 있게 한다. 구현한 웹서비스들의 효용성을 실험적으로 보이기 위하여 이러한 웹서비스들을 이용하여 박물관 관람객의 위치를 고려한 콘텐츠 출력 시스템 프로토타입을 구현한다.
