Digital 30sec Gridded Bathymetric Data of Korea Marginal Seas - KorBathy30s

摘要: Gridded bathymetric data of 30 seconds apart in Korea marginal seas are produced. In order to make the data, both updated gridded 1 minute on internet sites and all digital nautical charts issued by National Oceanographic Research Institute (NORI) Oct. 2007 used. The reference level is approximate lowest low water horizontal coordinates based WGS84 ellipsoid. Especially a developed computer program can collect sounding including depth contour directly from UTM converted which accuracy significantly improved. An interpolation method adopted produce compared analyzed against existing data. this we see detailed topographic features could not be found previous
