  • 삼면이 바다인 우리나라의 국토환경에서 해양공간정보에 대한 국민들의 수요가 증가하고 다양해짐에 따라, 육상 및 해상의 지리정보는 관련기관, 민간부분 및 일반인에게 확산하여 부가가치를 창출할 수 있는 사회간접자본으로서의 역할이 요구되고 있는 실정이다. 이에 해양수산부는 제2차 국가지리정보체계 기본계획에 입각하여, 21세기 디지털 해양건설의 초석을 마련하기 위하여 해양지리정보 사업을 추진하고 있다. 본 연구에서는 해양지리정보체계(MGIS: Marine Geographic Information System)사업의 일환으로 해양기본지리정보에 관한 연구를 통하여 해양기본지리정보의 구축 시 필요한 필수항목으로 도출되었던 항목을 기준으로 데이터 모델링 및 데이터구축지침서를 작성하였다. 또한, 향후 NGIS의 통합을 고려한 국가차원의 해양기본지리정보 구성(안)을 제시하였으며 데이터의 품질기준, 유지관리를 위한 방안을 마련하였다.

  • This study is about the change of coastline through using ASTER images. ASTER image is a sensor loaded in earth resources satellite shoot in Japan on Dec. 1999. It has 15m, 30m, 90m coastline, three sensors of VNIR, TIR and WIR, therefore it's possible to obtain more information on the Earth than the existing satellite images cause it contains various a wavelength range in spite of relatively economic image. The coastline is changed according to topography shape because it's strongly localized. Besides, it's one of the most important factors in MGIS(Marine Geographic Information System). Therefore, this study is accomplished by analysing variation after abstraction the coastline automatically by Vector Line from ASTER satellite images. The study result will be used as an important basic data when analysis the change of e coastline hereafter.

  • Shoreline changes its shapes and attribution dynamically by natural, unnatural acts and is the most information for country. These shorelines can apply to framework data of MGIS (Marine Geographic Information System), and they are getting important to implement a phase of monitoring around coastal areas. This study proposed an algorithm automatically extracting shorelines to use a new developed LiDAR (Light Detection And Ranging) data which is applying in ocean and coastal areas. Then, in result, it was compared to shorelines which is derived from ground survey. In result, it shows stable shorelines in various coast areas such as nature, artificial coast. Additionally, and a possibility of shoreline extraction through LiDAR data.
