Figure~\ref{fig:salvis-wm-250k} illustrates the original GDR250LT and the
|
||||
{\WM}--simplified version. As section~\ref{sec:analyzed-large-scale} explains,
|
||||
the algorithm tries to exaggerate many bends to a great size. However, GDR250LT
|
||||
takes the opposite approach --- only the very basic shapes of the largest bends
|
||||
are retained. Time and customers will tell, which approach is more appropriate,
|
||||
after the current {\WM} implementation receives some time and attention, as
|
||||
desired in section~\ref{sec:future-suggestions}.

\item What are the exaggeration limits when working with large scales?

Section~\ref{sec:national-large-scales} discusses examples that some

limits are necessary.
