\subsection{Comparing Generalized Result with National Spatial Datasets}
% TODO: GDR50LT and GDR250LT
\subsubsection{Background}
There are a few datasets used in this comparison: GDB10LT, GDR50LT and
GDR250LT. They are vector datasets, which include rivers. They can be
downloaded for free from \cite{nzt}. Here are the meanings of the codenames:
\begin{description}
\item[GDB10LT] is dataset of highest detail. Suited for maps of scale
1:\numprint{10000}.
\item[GDR50LT] is suited for maps of scale 1:\numprint{50000}.
\item[GDR250LT] offers least detail, and is suited for maps of
scale 1:\numprint{250000}.
\end{description}
During the analysis, we ran {\WM} on GDB10LT for 2 destination scales:
1:\numprint{50000} and 1:\numprint{250000}.\footnote{parameter calculation is
detailed in section~\ref{sec:bend-scaling-and-dimensions}.} This section
compares the resulting {\WM}--generalized rivers to GDR50LT and GDR250LT.
\subsubsection{Medium-scale (1:\numprint{50000})}
For our research location, the national dataset GDB10LT is almost equivalent to
GDR50LT. Figure~\ref{fig:salvis-gdr50-overlaid} illustrates it. Therefore, the
comparison between {\WM}--simplified GDB10LT and GDR50LT is equivalent to the
comparison between {\WM}--simplified GDB10LT and non--simplified GDR50LT, which
was covered in section~\ref{sec:analyzed-medium-scale}.
