Abstract

For the fine-scale resolution coastal mapping at the Manlipo beach, we have measure terrestrial KiDAR and survey Multibeam echo sounder. To georeferencing these differnet kind of data, we prejected and transformed unified coordinate system such as WGS84 with GRS80 ellipsoid for XY coordinate and IMSL(Incheon Mean Sea Level) for Z coordinate. The integration of these data, we constructed the DEM and DSM to utilize as input data at numerical inundation model and hazard map. Furthermore, through the 3D spatial analysis, we can monitor and analysis the beach process like a erosion and deposition.
