Abstract

Recently, new GIS applications such as gee portal and spatial data infrastructure are emerging. These are related to web computing techniques or methodologies based on web 2.0 paradigm, open API of portal, open source GIS, and international GIS standards which are independently on developing. The product of these applications can be realized in the linkage of those components. In this study, a case implementation concerning linkage with Google maps API and open source middleware named Deegree is carried out, and the results are discussed for open source uses in geo portal. Open source middleware supports various levels and types of OGC standards, so that it enables web publishing in the several web standard formats and data exchanges and interoperable uses between external database servers. Also the (unction extensions and the multi tier-based architecture within geo portal for specific purpose are possible.

지오포털이나 공간정보기반구축 등이 최근 공간정보 분야에서 주요한 연구 동향으로 부각되고 있다. 이러한 응용 분야는 Web 2.0과 관련된 다양한 웹 컴퓨팅 기법이나 방법론, 포털에서 제공하는 공개 API, 공개 소스 GIS, 국제 GIS 표준사양 등 부분적으로 발전되어 오고 있는 요소 기술들이 복합적으로 연동되는 성과로 구현이 가능하다. 본 연구에서는 구글 맵 API와 공개 소스 미들웨어인 Deegree를 연동하는 시험 연구를 수행하여 지오포털 구축에서의 공개 소스 적용 가능성을 검토해 보고자 한다. 공개 소스 미들웨어에서는 OGC 등의 국제 표준사양을 지원하므로 다양한 웹 출력 및 외부 데이터베이스 서버간의 자료 호환 및 상호운영이 가능하고 특정한 웹 서비스 구축 목적에 맞는 추가적인 기능의 구현이나 계층적 아키텍처 구현이 가능하게 한다.
