초록

지리정보의 상호 운용성을 제공하기 위해 제안된 GML은 무선 환경에서의 응용을 위해 다양한 동적 객체 스키마를 명세하고 있다. 이러한 GML 동적 객체 스키마는 시간의 변화에 따라 그 위치와 모양이 연속적으로 변화하는 이동객체의 표현을 지원하여, 이동객체의 위치 정보를 기반으로 다양한 응용 서비스를 제공하는 위치기반서비스에서 GML 활용도가 증대되고 있다. 특히, GML 질의어는 지리정보의 통합, 공간 연산자의 지원 등을 중심으로 많은 연구가 수행되었다. 그러나, 기존의 GML 질의어는 이동객체에 대한 질의를 고려하지 않고 있다. 따라서 이 논문에서는 GML 문서에 대한 이동객체 질의를 지원하기 위해 표준 XML 질의어인 XQuery를 확장한 이동객체 질의어를 제안한다. 또한, 제안질의를 위한 데이터 모델 및 대수 연산 그리고 다양한 이동객체 연산자를 설계하고, 제안 질의어를 돌풍 관제 시스템에 적용하여 제안 질의어가 다양한 위치기반서비스에 효과적으로 사용될 수 있음을 보인다.

GML proposed to offer interoperability of geography information is specifying various dynamic object schema for application in the wireless environment. These GML dynamic object schema supports the expression of moving objects that the position and shape change consecutively over time, so practical use of GML is increased in location-based service that provides various application services based on location information of moving objects. In particular, the conventional query languages about GML have been studied with priority given to the integration of geographic information, the support of spatial operations, and etc. However, it lacks the support for moving objects queries. Therefore, in this paper, we propose the moving objects query language that supports moving objects queries for GML documents by extension of XQuery that is standard in query language. Also, data model, algebra operation and various moving objects operators for the proposed query language are designed, and we apply the proposed query language to tornado government organization system to show that the proposed query language can be used effectively in various location-based service.
