+\section{Examples}\label{sec:examples}%
+
+The following map examples may be used as tutorials and
+starting point for own applications.
+Also see |mercatormap-example.tex| for a compilable full example.
+Note to do all preparations documented in \Fullref{sec:python}.

+\subsection{Reference Position}
+
+With \refKey{/mermap/supply/type}|=|\docValue{reference} a map with a
+\emph{reference position} is constructed. Here, Munich is taken as
+reference position and center of the map. Since the position is used
+more than once, it is stored with \refCom{mrcNPdef} for further reference.
+With \refKey{/mermap/supply/flex reference scale} the scale
+is set to 1:6\,000\,000. For the background map tiles, a
+\refKey{/mermap/supply/source} is selected for download.
+This setup is done by \refCom{mrcmap} while \refCom{mrcdrawmap} draws
+the downloaded map tiles.

+\subsection{Fitting Area}
+
+With \refKey{/mermap/supply/type}|=|\docValue{areafit} a map is constructed
+where a given area is fitted in. The following example lists some
+US-American cities and constructs an \refKey{/mermap/supply/area} which
+contains all of them. With \refKey{/mermap/supply/flex area fit}|=15mm| a
+border region is added.
+
+

+%-------------------------------------------------------------------------------
+\subsection{Fixed Boundaries}
+
+With \refKey{/mermap/supply/type}|=|\docValue{boundaries} a map is constructed
+with fixed boundaries. In contrast to the other map types, the document
+map size cannot be given directly but derives from the map setup. This bears
+the risk of too large maps. The following example is a map with exact
+boundaries \mrcformlat{-45} to \mrcformlat{-10}
+and \mrcformlon{110} to \mrcformlon{155}. A decent \refKey{/mermap/supply/zoom}
+is 5 (every zoom step doubles the map size in each direction).

+\subsection{Map Without Map Tiles}
+
+There is no coercion to use downloaded map tiles, if they are not needed or
+wanted. With \refKey{/mermap/supply/target}|=none| no map tiles are downloaded.
+The following example draws a rough polygon shape of Germany using
+\refEnv{mrcroute*}.

+\subsection{Flexible Zoom}
+
+Map tiles are only provided at fixed zoom levels with natural numbers,
+but the package allows a \refKey{/mermap/flex zoom} with rational numbers.
+The flexible zoom is realized by combining a suitable fixed zoom with
+an adapted document tile scaling, see \Fullref{sec:flexible_tile_size}.
+The following example shows a more or less smooth zoom increase.
+The same technique is used by all options starting with |flex|, e.g.
+\refKey{/mermap/supply/flex reference scale}
+or \refKey{/mermap/supply/flex area fit}
+as seen in the examples before.
