Inundation maps show the places which can be flooded after the tsunami. These maps are
valuable sources to show the zones threatened. NamiDANCE gives the sea surface profiles as output
files in .grd format along the bathymetry. These output files are then converted into ASCII XYZ.dat files containing longitude, latitude and wave height attributes along the bathymetry at each grid as point data. Those points are used as an input file for GIS software. . Therefore, beside spatial attributes of the points, inundation values are also added to the database.
