dc.description.abstract 한국 주변해역(30oN ~ 44oN, 117oE ~ 143oE)에 대한 30초 간격의 격자수심을 산출하였다. 자료 생산을 위해 공개된 1분 수심 최신자료와 2007년 간행된 국립해양조사원의 모든 수치해도를 이용하였다. 격자수심의 기준면은 약 최저저조면이며 경위도는 WGS84 좌표계를 사용하였다. 특히 수치해도에서 측심자료를 추출하고 이를 WGS84 좌표로 변환하는 프로그램을 개발하여 자료의 정확성을 꾀하였고 보간법을 이용한 산출된 자료를 기존 자료와 비교분석하였다. 본 수심자료에서는 기존 격자수심과 달리 보다 상세하고 정확한 지형을 볼 수 있다. Gridded bathymetric data of 30 seconds apart in Korea marginal seas (30∘N∼44∘N,117∘E∼143∘E) are produced. In order to make the data, both updated gridded data of 1 minute apart on internet sites and all the digital nautical charts issued by National Oceanographic Research Institute (NORI) in Oct. 2007 are used. The reference level of the gridded data is approximate level of lowest low water and the horizontal coordinates are based on the WGS84 ellipsoid. Especially a developed computer program can collect all the sounding data including depth contour directly from the digital charts and UTM coordinates of the data are converted to the WGS84 coordinates from which accuracy of data is significantly improved. An interpolation method is adopted to produce the gridded data which are compared and analyzed against the existing gridded data. In this gridded data we can see significantly detailed topographic features which could not be found in the previous data. -
