The purpose of this section is to show the differences of impact and the importance of using the best possible data set. Given that the 1.5m AHD contour line is further from the coast for the DTED data than the DLI data, we expect the inundation to extend further and thus be greater than that seen in Figure \ref{fig:MSL_max_inundation}. Further, the impact modelling will result in inflated structural and contents loss figures as well as numbers of people affected. These results point to the need for the best available data so that more accurate predictions regarding the inundation can be made.
