Abstract
To predict and prevent natural disaster such as inundation at the coastal area, the offer of precise forecast andhazard map is necessary. The accuracy of inundation prediction and hazard map is preliminarily determined bythe coastal geospatial information’s accuracy among other factors. Considering the characteristic of coastal areaas an intertidal zone, it has always changed following by the tide and wave having the coexistence of connectionsea and land. Thus, there are not exist sufficient geospatial information in the established topographic andbathymetric data.Therefore, we have measured topography and surveyed bathymetry using terrestrial LiDAR and MBES to makeprecise and fine-scale resolution coastal map. For the geo-referencing of these two kinds of data, we have doneNetwork-RTK and tide measurement. After unify x, y, z coordinate system, we have constructed accurate finescaleresolution coastal mapped DEM and DSM through the integration of LiDAR and MBES data withregistering other supplementary data. Now it has used to input data for the numerical inundation model andhazard map. It can also possible to use monitoring and analysis of beach process such as an erosion/depositionthrough cyclic long-term measurement considering with the artificial beach transition based on GIS-based 3Dspatial analysis.
