    88   Thai Navy charts no. 45 and no. 362; and

    9091  bathymetry chart, no. 358, which covers Patong Bay and the

    165166\subsubsection{Topography Data}
    166 The 1 second onshore topography for Patong Beach provided by the CCOP was
    167 merged with the nearshore 1 second bathymetry described in Section
    168 \ref{sec:bathymetry data} to provide a seamless terrain model for the
    169 bay and community as shown in Figure~\ref{fig:patong_bathymetry}.
     167A 1 second grid comprising the onshore topography and the nearshore bathymetry
     168for Patong Beach was created from the Navy charts (described in Section \ref{sec:bathymetry data}) and from
     1691 m and 10 m elevation contours provided in a GIS data set which was also provided by the CCOP
     170(see Section \ref{sec:inundation data} for details).
     171The 1 second terrain model for the and community as shown in Figure~\ref{fig:patong_bathymetry}.
     172
     173Two 1/3 second grids were created: One for the saddle point covering Merlin and Tri Trang Beaches
     174and one for Patong city and its immediate shore area.
     175These grids were based on
     176the same data used for the 1 second data grid.
     177The patong city grid was further modified based on
     178satellite imagery to include
     179the river and lakes towards the south of Patong city which were not part of the GIS dataset.
     180The depth of the river and lake system was set uniformly to -1 m.

    184195Human-made buildings and structures can significantly affect tsunami
    185196inundation. The footprint and number of floors of the
    186 buildings in Patong Bay were extracted from a GIS data set which was also provided by the CCOP (see Section \ref{sec:inundation data} for details).
     197buildings in Patong Bay were extracted from the GIS data set from CCOP.
    187198The heights of these
    188199buildings were estimated assuming that each floor has a height of 3 m and they
    189200were added to the topographic dataset.

    5252  the pivot line (the region between the uplift and subsided region
    53   where the uplift is zero) derived from remote sensing

     54  were no changes in the amount of reef or land exposure before and after
     55the earthquake (\cite{meltzner06}). All the
    5556  observational data are from the dataset collated
    5657  by~\cite{chlieh07}.}
     
    6970sequence of grids was used. The grid resolution of the nested grids
    7071went from 27 arc seconds in the coarsest grid, down to nine arc seconds
    71 in the second grid, three arc seconds in the third grid and finally one arc
    72 second in the finest grid near Patong. The computational domain is
     72in the second grid and three arc seconds in the third grid. The computational domain is
    7373shown in Figure~\ref{fig:computational_domain}.

    119119and \textsc{anuga} models was chosen to roughly follow the 100~m depth
    120 contour along the west coast of Phuket Island. The computational
     120contour along the west coast of Phuket Island. Data from the
     1213 second grid was decimated to match the resolution chosen in ANUGA.

    133135region in Patong Bay. The coarse resolution was chosen to be
    134136commensurate with the model output from the \textsc{ursga} model (FIXME (Ole): Richard says that the ursga model used all four grids which would mean that the
    135 resolution at the ANUGA boundary was 1 second or about 30m.
     137resolution at the ANUGA boundary was 1 second or about 30 m.
    136138This is not consistent with my memory and certainly not with us choosing a
    137 resolution of 440m. John, do you remember what the spacing was between the
     139resolution of 440 m. John, do you remember what the spacing was between the
    138140URSGA points? Did we weed them out or did we take them as they were?)
