Abstract

According to wide civilian utilization of multi sensor satellite information, practical needs for fusion processing and interoperable operation with multiple remote sensing imageries within distributed remote server are being increased. For this task, OGC standards with respect to satellite images and its derived products are crucial factors. This study is to present an applicability of WPS through testing implementation of image processing algorithm. Open sources such as Geoserver and OTB were used linked to WPS application for implementation. WPS can be solely used for web service supporting geoprocessing algorithm, but technical consideration compromising with other important standard protocols including WMS, WFS, WCS, or WMTS is necessary to build full featured geo web for remote sensing imageries. It is expected that application of these international standards for geo-spatial information is an important approach to produce value-added results by interoperable processing between interorganizations or information dissemination containing practical satellite image processing functionalities.

위성 영상정보의 민간 활용이 확대되면서 원격 서버에서 다중 위성 영상정보의 상호 운영과 융합처리 서비스에 대한 실제적인 필요성이 증가하고 있다. 이러한 추세에 따라 위성 영상정보에서 얻어지는 파생 정보를 위한 OGC 표준의 중요성이 강조되고 있다. 이번 연구에서는 GeoServer와 OTB와 같은 오픈소스를 기반으로 하여 WPS 표준에 대한 시험 구현을 통하여 위성정보 처리 분야에서 이러한 표준의 적용 가능성을 예시하고자 하였다. WPS 표준은 단독으로 적용될 수도 있으나 위성영상 정보처리를 포함하는 공간정보 웹 포털은 WMS, WFS, WCS와 WMTS 뿐만 아니라 카탈로그 서비스 표준 등의 요소를 같이 고려해야 한다. 앞으로 이러한 공간정보 국제표준 사양은 보다 많은 실무 적용 사례의 구축과 지속적인 관련 기술 개발을 통하여 실무적인 분석처리 기능을 제공하는 위성영상 정보시스템의 기관 간 상호운영이나 정보 콘텐츠의 효과적인 유통 체계 구축을 위한 중요한 접근 방식이 될 것으로 기대한다.
