Evaluation of Bathymetry Accuracy near Coastlines of West Sea of Korea from Satellite Altimetry and Multi-beam

Abstract

Bathymetric mapping was traditionally implemented by shipborne single-beam, multi-beam, and side-scan sonar sensors. There are big tidal effects and the foreshore on western coastal zones of Korea. These days airborne bathymetric LiDAR technique has been attempted to get seamless geospatial data from land to submarine topography. This study focuses on generating bathymetric data near coastlines from multi-beam bathymetry and satellite altimetry gravity anomalies. The estimated bathymetry is compared with multi-beam and airborne bathymetric LiDAR data for the accuracy assessment.
