     4208\subsubsection{How do I extract elevation and other quantities from a SWW file?}
     4209
     4210The function \code{sww2dem} can extract any quantity, or expression using
     4211quantities, from a SWW file as used in
     4212the Cairns example described earlier. This function is used in \code{ExportResults.py}
     4213in the Cairns demo folder where stage, absolute momentum, depth, speed and elevation
     4214can be exported from the input sww file. Note that depth, absolute momentum and speed
     4215are expressions and stage and elevation are quantities. In addition to extracting a particular
     4216quantity or expression, the user can define a region to extract these values by
     4217defining the minimum and maximum of both the easting and northing coordinates. The function
     4218also calls for a grid resolution, or cell size, to extract these values at. It is
     4219recommended to align this resolution with the mesh resolution in the desired region and to not
     4220generate a fine grid where the model output cannot support that resolution.
