\begin{itemize}

            \item IPCC projections (global and ``downscaled'' for NZ)
            \item ORC natural hazards database layers: alluvial fans, flooding, coastal inundation {\tiny (including storm surge \& tsunami)}

        \item Simple ``bathtub'' model of South Dunedin:
        \begin{itemize}
            \item IPCC scenarios: SSP1 (RCP2.6), SSP2 (RCP4.5), SSP5 (RCP8.5)
            \item sea level rise only; no groundwater, geology, storm surge, …
            \item not overly realistic, not predictive
            \item non-interactive visualisations
        \end{itemize}

\item Initial focus on ``climate-change flooding related risks to residential property values across space and time, and the related implications for financial stability.''

\item ArcGIS model with $\approx$ 40,000 layers that model outcomes of combinations of various factors. {\tiny (e.g., planning decisions)}

% Lidar data for Dunedin (available through LINZ)
% DEM (Digital Elevation Model) data at varying resolutions for the whole country.
% Property values nationwide and property borders/tiles (the latter available through LINZ)
% Groundwater data from GNS Science
% They're looking at getting access to precipitation projections.
% Global IPCC seal level rises (which is very similar to regional sea level rise) 
% Infrastructure data available through LINZ/OpenStreetMaps - this could be used to model where sites would become inaccessible
% NIWA has storm surge/ coastal inundation models but apparently these are inaccurate/ still being redeveloped.
% Quyen suggested looking at drought data as well however STRAND doesn't currently focus on this.

\begin{itemize}
        \item Integrate additional hazards/risks:

\item Further develop interactive prototype:

            \item user study with Aukaha (\& broader community?)
