+ The \texttt{mercatormap} package extends \tikzname\ with tools to
+ create map graphics. The provided coordinate system relies on the
+ Web Mercator projection used on the Web by OpenStreetMap and others.
+ The package supports the seamless integration of graphics
+ from public map tile servers by a Python script. Also, common map
+ elements like markers, geodetic networks, bar scales, routes, orthodrome
+ pieces, and more are part of the package.

+
+%-------------------------------------------------------------------------------
+\subsection{Option Setting}
+\begin{docCommand}{mermapset}{\marg{options}}
+ Sets \meta{options} for all following maps inside the current \TeX\ group.
+ All options share the common prefix |/mermap/|, e.g. for setting
+ \refKey{/mermap/vicinity} use
+ \begin{dispListing}
+ \mermapset{vicinity=3cm}
+ \end{dispListing}
+ Also see \refCom{mrcdefinemap}, \refCom{mermapsetsupply},
+ and \refCom{mermapsetmarker}.\par
+ Note that the options by \refCom{mermapset} are |expl3| \cite{package:expl3}
+ keys while \tikzname\ \cite{package:tikz} uses its own key management.
+\end{docCommand}
+
+
+\clearpage
+%-------------------------------------------------------------------------------
+\subsection{Manual Map Definition}
+The following map definition is only relevant, if no script setup is used
+and maps are generated completely manually.
+See \Fullref{sec:automated_map} for script aided map definitions.
+
+\begin{docCommand}{mrcdefinemap}{\marg{options}}
+ Establishes a map inside a |tikzpicture| environment following
+ and applying the given \meta{options}.
+ All options share the common prefix |/mermap/mapdef/|.
+ After \refCom{mrcdefinemap} is applied, map drawing and map coordinates
+ can be used.
+ \begin{itemize}
+ \item\refCom{mrcdefinemap} can be used directly, if no tile download
+ and no script setup is intended.
+ \item\refCom{mrcdefinemap} is implicitly used with
+ \refCom{mrcapplymap} and \refCom{mrcmap}. In this case, all options are
+ also set implicitly.
+ \end{itemize}
+\end{docCommand}
+
+
+\begin{docMrcKey}{mapdef/north}{=\meta{map north latitude}}{no default, initially 50}
+ Northern latitude degree of the visible map, possibly negative for the southern hemisphere,
+ lower than $90$ but always larger than \refKey{/mermap/mapdef/south}.
+ It is accessible as \docAuxCommand{mrcmapnorth} (use read-only).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/south}{=\meta{map south latitude}}{no default, initially 48}
+ Southern latitude degree of the visible map, possibly negative for the southern hemisphere,
+ larger than $-90$ but always lower than \refKey{/mermap/mapdef/north}.
+ It is accessible as \docAuxCommand{mrcmapsouth} (use read-only).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/west}{=\meta{map west longitude}}{no default, initially 11}
+ Western longitude degree of the visible map, possibly negative for the western hemisphere,
+ possibly shifted periodically, but always lower than \refKey{/mermap/mapdef/east}.
+ It is accessible as \docAuxCommand{mrcmapwest} (use read-only).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/east}{=\meta{map east longitude}}{no default, initially 13}
+ Eastern longitude degree of the visible map, possibly negative for the western hemisphere,
+ possibly shifted periodically, but always larger than \refKey{/mermap/mapdef/west}.
+ It is accessible as \docAuxCommand{mrcmapeast} (use read-only).
+\end{docMrcKey}
+
+
+%-------------------------------------------------------------------------------
+\subsection{Further Map Definition Options}
+
+
+The following options are typically implicitly set by \refCom{mrcapplymap}
+and not manually by \refCom{mrcdefinemap}. However, some values are
+computationally used in all cases. They can be ignored as pure technical
+information.
+
+\begin{docMrcKey}{mapdef/xmin}{=\meta{map tile x minimum}}{no default, initially 271}
+ Minimal $x$ coordinate of the map tiles.
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/xmax}{=\meta{map tile x maximum}}{no default, initially 275}
+ Maximal $x$ coordinate of the map tiles.
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/ymin}{=\meta{map tile y minimum}}{no default, initially 173}
+ Minimal $y$ coordinate of the map tiles.
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/ymax}{=\meta{map tile y maximum}}{no default, initially 177}
+ Maximal $y$ coordinate of the map tiles.
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/zoom}{=\meta{map zoom}}{no default, initially 9}
+ Map tile zoom factor alias $z$ coordinate of the map tiles.
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/pixelwidth}{=\meta{map width in pixels}}{no default, initially 100}
+ Width of the visible map expressed in pixels of the source file(s).
+ It is accessible as \docAuxCommand{mrcpixelwidth} (use read-only).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/pixelheight}{=\meta{map height in tiles}}{no default, initially 100}
+ Height of the visible map expressed in pixels of the source file(s).
+ It is accessible as \docAuxCommand{mrcpixelheight} (use read-only).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/westoffset}{=\meta{map tile offset (west)}}{no default, initially 0}
+ Distance of the visible map from the western edge of the most western tile
+ expressed in tiles (range from 0 to 1).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/northoffset}{=\meta{map tile offset (north)}}{no default, initially 0}
+ Distance of the visible map from the northern edge of the most northern tile
+ expressed in tiles (range from 0 to 1).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/southoffset}{=\meta{map tile offset (south)}}{no default, initially 0}
+ Distance of the visible map from the southern edge of the most southern tile
+ expressed in tiles (range from 0 to 1).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/basename}{=\meta{map tile base name}}{no default, initially \texttt{tiles/tile}}
+ File base name for the tiles.
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/attribution}{=\meta{attribution text}}{no default, initially empty}
+ Attribution text for the map source. Typically, it acknowledges the copyright
+ of the map data provider. It may contain hyperlinks.
+ It is accessible as \docAuxCommand{mrcmapattribution} (use read-only).
+\end{docMrcKey}
+
+\begin{docMrcKey}{mapdef/attribution print}{=\meta{attribution text}}{no default, initially empty}
+ Attribution text for the map source.
+ In contrast to \refKey{/mermap/mapdef/attribution} it is intended for media
+ that does not support hyperlinks like printed posters, books, etc.
+ It is accessible as \docAuxCommand{mrcmapattributionprint} (use read-only).
+\end{docMrcKey}
+
+
+\begin{docMrcKey}{mapdef/resource}{=\meta{map resource}}{no default, initially |none|}
+ Available map resource with following feasible values:
+ \begin{itemize}

+\subsection{Map Coordinate System}
+After a map is defined inside a |tikzpicture| environment
+by \refCom{mrcdefinemap}, \refCom{mrcapplymap}, or \refCom{mrcmap},
+a Mercator map coordinate system can be used.
+The border of the visible map is denoted by a \tikzname\ node \docNode{mrcmap}.
+
+\tikzsetnextfilename{def_coordinate_system}%
+\begin{dispExample}
+\begin{tikzpicture}
+ \mrcNPdef{nuremberg}{49.45522}{11.07631}

+ node[below] {M\"unchen};
+ \fill (mrc cs:lat=53.550556,lon=9.993333) circle (2pt)
+ node[above] {Hamburg};
+ \fill (mrcq cs:52.518611:13.408333) circle (2pt)
+ node[left] {Berlin};

+The |mrc cs| coordinate system defines a map point by
+\refKey{/mermap/cs/latitude} and \refKey{/mermap/cs/longitude}
+
+\begin{docMrcKey}{cs/latitude}{=\meta{latitude}}{no default}
+ Sets the \meta{latitude} of a map point.
+\end{docMrcKey}

+\begin{docMrcKey}{cs/longitude}{=\meta{longitude}}{no default}

+ \fill (mrc cs:latitude=48.137222,longitude=11.575556) circle (2pt);

+A map point can also be defined by shorter variants
+\refKey{/mermap/cs/lat} and \refKey{/mermap/cs/lon}
+
+\begin{docMrcKey}{cs/lat}{=\meta{latitude}}{no default}
+ Sets the \meta{latitude} of a map point.

+\subsection{Named Positions}\label{sec:names_positions}
+
+
+\begin{docCommand}{mrcNPdef}{\marg{name}\marg{latitude}\marg{longitude}}
+ A coordinate pair of \meta{latitude} and \meta{longitude}
+ can be saved as \emph{named position} (NP) to a \meta{name} for later use.
+ The \emph{named position} just stores the given values as evaluated
+ floating points but without coordinate system processing.
+ Therefore, a named position can be used outside a map definition
+ or |tikzpicture| environment, even as a preset for the whole document.
+ Note that this saving is not global but only effective inside the
+ current \TeX\ group.
+ \begin{dispListing}
+ \mrcNPdef{nuremberg}{49.45522}{11.07631}

+
+\begin{docCommand}{mrcNPfrompoint}{\marg{name}\marg{\tikzname\ point}}
+ \emph{Latitude} and \emph{longitude} of a given \meta{\tikzname\ point} are
+ calculated and saved as \emph{named position} (NP) with given \meta{name}.
+ \refCom{mrcNPfrompoint} can only be used after a valid a map definition
+ inside a |tikzpicture| environment.
+ \begin{dispListing}
+ \mrcNPfrompoint{mapcenter}{mrcmap.center}

+\begin{docCommand}{mrcNPlat}{\marg{name}}
+ Inserts the \emph{latitude} of a \emph{named position} with given \meta{name}.
+ \refCom{mrcNPlat} is expandable and may be used in floating point expressions.
+ \begin{dispExample}
+ \mrcNPdef{nuremberg}{49.45522}{11.07631}
+ Latitude: \mrcNPlat{nuremberg}\\
+ Longitude: \mrcNPlon{nuremberg}
+ \end{dispExample}
+\end{docCommand}
+
+
+\begin{docCommand}{mrcNPlon}{\marg{name}}

+\subsection{Tests for Points to be inside or outside a Map}
+
+When a map is drawn, \refCom{mrcclipmap} can be used to set up a
+\tikzname\ clip environment which automatically removes all content which
+is not inside the defined map. However, the \tikzname\ position of a geographic
+point has to be computed first to decide, if this point is to be drawn.
+Since \TeX\ length registers do not allow large dimensions, compiler errors
+are possible to happen.
+
+The following tests check given geographic coordinates before they are
+transformed to \TeX\ dimensions and avoid such compiler errors.
+
+\begin{docCommand}{ifmrcinmap}{\marg{latitude}\marg{longitude}\marg{true}\marg{false}}
+ If the given \meta{latitude} and \meta{longitude} describes a point
+ inside the visible map, the \meta{true} code is executed, otherwise
+ the \meta{false} code.\par
+ Inside the \meta{true} code a \tikzname\ coordinate \docNode{mrcpos}
+ describes the given point. Also, \docNode{mrclastpos} denotes the
+ \emph{last} position before.
+ \begin{dispListing}
+ \ifmrcinmap{48.137222}{11.575556}{\fill (mrcpos) circle (2pt);}{}
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{ifmrcNPinmap}{\marg{name}\marg{true}\marg{false}}
+ If the given \emph{named position} (NP) \meta{name} describes a point
+ inside the visible map, the \meta{true} code is executed, otherwise
+ the \meta{false} code.
+ \begin{dispListing}
+ \mrcNPdef{munich}{48.137222}{11.575556}
+ \ifmrcNPinmap{munich}{\fill (mrcpos) circle (2pt);}{}
+ \end{dispListing}
+\end{docCommand}
+
+
+Very similar to \refCom{ifmrcinmap} is \refCom{ifmrcinvicinity}.
+
+\begin{docCommand}{ifmrcinvicinity}{\marg{latitude}\marg{longitude}\marg{true}\marg{false}}
+ If the given \meta{latitude} and \meta{longitude} describes a point
+ inside a vicinity of the visible map, i.e. the map \emph{plus} a margin of \refKey{/mermap/vicinity},
+ the \meta{true} code is executed, otherwise
+ the \meta{false} code.\par
+ Inside the \meta{true} code a \tikzname\ coordinate \docNode{mrcpos}
+ describes the given point. Also, \docNode{mrclastpos} denotes the
+ \emph{last} position before.\par
+ \refCom{ifmrcinvicinity} may be used for objects of a certain size like
+ markers which could be partly visible even when their reference point
+ is outside the visible map (but nearby).
+\begin{dispListing}
+ \ifmrcinvicinity{48.137222}{11.575556}{\fill (mrcpos) circle (2pt);}{}

+\subsection{Flexible Tile Size}\label{sec:flexible_tile_size}
+
+Typically, the pixel size of a map tile is fixed and a map tile is a
+pixel graphics file. The actual size of such an included picture inside
+the document is freely selectable. Note that a very small
+\refKey{/mermap/tile size} results in very small map lettering,
+while a very large \refKey{/mermap/tile size} results results in
+very blurred images.
+
+The general idea of a \emph{flexible} tile size is to specify an aspired
+tile size called \refKey{/mermap/flex tile size} and to give \LaTeX\
+the freedom to select \refKey{/mermap/tile size} in \emph{about the same size}
+as \refKey{/mermap/flex tile size}.
+This freedom is used to achieve a \emph{pseudo zoom} called
+\refKey{/mermap/flex zoom} which is a nearly arbitrary rational number instead
+of \refKey{/mermap/supply/zoom} which is a natural number.
+
+This \emph{pseudo zoom} is applied by several options which share \emph{flex}
+in their names, e.g.
+\refKey{/mermap/flex scale}, \refKey{/mermap/named flex scale},
+\refKey{/mermap/supply/flex reference scale},
+\refKey{/mermap/supply/flex area scale},
+\refKey{/mermap/supply/flex area fit}.
+
+
+
+\begin{docMrcKey}{tile size}{=\meta{length}}{no default, initially |32.512mm|}
+ Width and height of a drawn tile picture are set to \meta{length}.
+ For standard tiles with 256 times 256 pixels a tile size of
+ \SI{32.512}{mm} = \SI{1.28}{in} results in an approximate
+ \SI{200}{dpi} output for the document.
+ For a |beamer| document, consider to use a \refKey{/mermap/tile size} of
+ \SI{21.333333}{mm} to get approximate 1:1 pixel input and output (depending on |beamer| settings
+ and used hardware). Also see \refKey{/mermap/mapdef/tile size}.
+\end{docMrcKey}
+
+\begin{docMrcKey}{flex tile size}{=\meta{length}}{no default, initially |32.512mm|}
+ Aspired width and height of a tile picture are set to \meta{length}.
+ This value is used while applying \refKey{/mermap/flex zoom}.
+\end{docMrcKey}
+
+
+\begin{docMrcKey}{flex zoom}{=\meta{pseudo zoom}}{style, no default}
+ This style sets \refKey{/mermap/supply/zoom} and \refKey{/mermap/tile size} in combination.
+ \begin{itemize}
+ \item
+ If \meta{pseudo zoom} is a natural number,
+ \refKey{/mermap/supply/zoom} is set to \meta{pseudo zoom} and
+ \refKey{/mermap/tile size} is set to \refKey{/mermap/flex tile size}.
+ \item Otherwise, \refKey{/mermap/supply/zoom} is set to the natural number
+ closest to \meta{pseudo zoom} and \refKey{/mermap/tile size} is such
+ enlarged or reduced that the \meta{pseudo zoom} value is simulated,
+ i.e. the \emph{impression} of a rational zoom factor is given.
+ \end{itemize}
+ Note that \refKey{/mermap/flex zoom} has to be used \emph{before}
+ \refCom{mrcsupplymap} or \refCom{mrcmap}, because the zoom setup is
+ adapted.
+\end{docMrcKey}
+
+
+\clearpage
+\begin{docMrcKey}{flex scale}{=\meta{scale denominator}:\meta{latitude}}{style, no default}
+ For different latitude scopes, an identical zoom factor produces maps of
+ different scale. With \refKey{/mermap/flex scale}, a \refKey{/mermap/flex zoom}
+ is computed to achieve the given \meta{scale denominator} at a given \meta{latitude}.
+ Note that this only applies to the center of a map. If the produced
+ map is not centered at \meta{latitude}, the produced scale may
+ differ from the intended one.
+ Also see \refKey{/mermap/supply/flex reference scale}.

+\subsection{Geodetic Network}
+
+\begin{docCommand}{mrcdrawnetwork}{\oarg{options}}
+ Draws a geodetic network with meridians and parallels.
+ All \meta{options} share the common prefix |/mermap/|.
+ The displayed lines are selected automatically according to some tuning
+ parameters.
+ The map is sliced in \emph{about} maximal \refKey{/mermap/network pieces} in each
+ direction. Meridians and parallels share a minimal distance of
+ \emph{about} \refKey{/mermap/network distance}. The algorithm is
+ allowed to violate these conditions \emph{somewhat}.

+\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*}.

+The following example shows a more or less smooth zoom increase.
+The same technique is used by all options starting with |flex|, e.g.

+\section{Introduction}%
+
+The \texttt{mercatormap} package enables map drawing with the
+Web Mercator projection. This is done as an extension to
+\tikzname\ \cite{package:tikz} with is complemented by a map
+coordinate system and many additional commands and options to add elements
+like markers, geodetic networks, bar scales, routes, orthodrome
+pieces, distance calculations, etc. Also, the seamless integration of graphics
+from public map tile servers is provided through a Python script.
+
+If you are interested in the mathematical background of the Web Mercator projection
+and the algorithms of this packages, you are invited to read
+\enquote{\fullcite{Sturm:2020}}.
+
+With very few exceptions, the package is programmed with the
+|expl3| \cite{package:expl3} programming interface for \LaTeX3
+and loads the packages
+|xparse| \cite{package:xparse} and |siunitx| \cite{package:siunitx}.

+%-------------------------------------------------------------------------------
+\subsection{Quick Start}
+
+The package is accompanied with a Python script. You should read
+\Fullref{sec:python} for the Python preparations.
+The package can be used in three ways:
+\begin{itemize}
+\item Completely without the Python script.
+ This is not recommended, because the usage will be quite restricted.
+\item With Python script, but without map tile download.
+ There is no usage restriction, but you have to create all content yourself.
+ To prevent map tile download, set
+ \begin{dispListing}
+ \mermapset{supply/target=none}
+ \end{dispListing}
+\item With Python script and map tile download.
+ You need permission and access to a map tile server.
+ \Fullref{sec:maptileserver} lists a selection of servers with free
+ access (some require registration of an API key).
+\end{itemize}
+
+After Python is prepared, you may try to compile
+|mercatormap-example.tex| (found in the documentation directory)
+which contains a map of Bavaria with map tile download.
+\Fullref{sec:examples} exhibits further examples which may serve as
+tutorials what can be done. After the examples you find the reference
+manual for the package.
+

+%-------------------------------------------------------------------------------
+\subsection{Installation of Python and Packages}\label{sec:python}
+
+A Python~3 script is part of the |mercatormap| package.
+The main purpose of this script is to download selected map tiles for
+the maps of the document. Also, some coordinate system computation is
+done by this script.
+
+\subsubsection{Python 3}
+Python 3 is a required prerequisite and can be downloaded from\\
+\url{https://www.python.org/downloads/}\\
+On systems like Linux Python is typically already installed.\par
+To test your installation, type into a command or terminal window:
+\begin{dispListing}
+ python --version
+\end{dispListing}
+This should give a version number starting with 3. Otherwise, try
+\begin{dispListing}
+ python3 --version
+\end{dispListing}
+If this is successful, \refKey{/mermap/python} has to be adapted to |python3|
+
+\subsubsection{Python Packages}
+The Python packages |Pillow| (\url{https://pypi.org/project/Pillow/})
+and |requests| (\url{https://pypi.org/project/requests/}) have to be present.
+With some luck, they are already installed. With
+\begin{dispListing}
+ pip3 list
+\end{dispListing}
+and/or
+\begin{dispListing}
+ pip3 list --user
+\end{dispListing}
+the installed packages are listed. If |Pillow| and |requests| are not
+among these package, they have to be added by
+\begin{dispListing}
+ pip3 install --user Pillow
+ pip3 install --user requests
+\end{dispListing}
+or
+\begin{dispListing}
+ pip3 install Pillow
+ pip3 install requests
+\end{dispListing}
+The second choice needs administrative rights and may give conflicts
+with package managers. Pythonians know furthers installation methods.
+
+\subsubsection{Document Setup}
+For your map document you need the following:
+\begin{itemize}
+\item Add \refCom{mrcactivatescript} to the document preamble.
+ Without this command, the script is not active.
+\item Compile the map document with the |--shell-escape| compiler option.
+ This allows to execute external programs like the Python script.\\
+ \textbf{Be aware that |-||-shell-escape| should only be used
+ with trusted documents. Note that external programs can do anything!}
+\end{itemize}

+\section{Limitations and Caveats}%
+
+%-------------------------------------------------------------------------------
+\subsection{No Polar Regions}
+ The standard Mercator projection is not suited for north or south polar
+ regions.
+ The Web Mercator projections only covers
+ positions between \mrcformlat{-85.0511} and \mrcformlat{85.0511}
+ with map tiles. Equally, the |mercatormap| package does only provide support for
+ this area.
+
+ If your map overlaps to south of \mrcformlat{-85.0511} or to north of \mrcformlat{85.0511},
+ compiler errors are possible because of internal computation limitations.
+ In any case, there are no map tiles.
+
+ \tikzsetnextfilename{limit_polar}%
+ \begin{dispExample}
+ \begin{tikzpicture}
+ \mrcmap[type=reference,latitude=-85.0511,longitude=0,zoom=3,
+ source=opentopomap,
+ tex width=\linewidth, tex height=8cm]{}
+ \mrcdrawmap
+ \node[above=4mm,font=\fontsize{7pt}{7pt}\sffamily] at (mrcmap.south)
+ {\mrcmapattribution};
+ \mrcclipmap
+ \mrcdrawnetwork[network pieces=10,network distance=10mm]
+ \path[draw] (mrcmap.south west) rectangle (mrcmap.north east);
+ \mrcmarker{type=pin,position=-85.0511:0,
+ contents={End of the mapped world}}
+ \end{tikzpicture}
+ \end{dispExample}
+
+%-------------------------------------------------------------------------------
+\clearpage
+\subsection{International Dateline (180th Meridian)}\label{sec:dateline}
+ If your map includes the 180th meridian (more or less the international dateline),
+ remember that the eastern hemisphere lies \emph{west} and
+ the western hemisphere lies \emph{east} for your map.
+ Consider the following example displaying Vladivostok and Anchorage.
+ Here, \refKey{/mermap/supply/west} is set to \ang{130}\,E (|130|)
+ and \refKey{/mermap/supply/east} is set to \ang{149}\,W (|211| instead of |-149|).
+
+ There is some automatic correction for positions to fit inside the
+ defined map (see Anchorage in the example below), but
+ \emph{west} should be lower than \emph{east}.
+
+ \tikzsetnextfilename{limit_dateline}%
+ \begin{dispExample}
+ % \mrcsetapikey{openrouteservice}{YOUR-API-KEY} % registered key
+ \begin{tikzpicture}
+ \mrcmap[type=areafit,tex width=\linewidth,tex height=8cm,
+ source=openrouteservice mapsurfer,
+ south=42,north=62,west=130,east=-149+360]{}
+ \mrcdrawmap
+ \node[below,font=\fontsize{7pt}{7pt}\sffamily] at (mrcmap.south)
+ {\mrcmapattribution};
+ \mrcclipmap
+ \draw (mrcmap.south west) rectangle (mrcmap.north east);
+ \draw (mrc cs:lat=\mrcmapsouth,lon=180)
+ -- node[sloped,above] {180th meridian}
+ node[sloped,below,red] {add 360 to longitude for eastern border}
+ (mrc cs:lat=\mrcmapnorth,lon=180);
+ \mrcmarker{type=pin,position=61.22:-149.88,contents={Anchorage}}
+ \mrcmarker{type=pin,position=43.12:131.9, contents={Vladivostok}}
+ \end{tikzpicture}
+ \end{dispExample}
+
+%-------------------------------------------------------------------------------
+\clearpage
+\subsection{Very small Scale Maps}
+ If a map has a very small scale, a coordinate point may appear more than once
+ on the map. But, the map coordinates of this package will only
+ pilot to a single point:
+
+ \tikzsetnextfilename{limit_small_scale_1}%
+ \begin{dispExample}
+ \begin{tikzpicture}
+ \mrcmap[type=reference,latitude=48.14,longitude=11.57,
+ source=opentopomap,
+ tex width=\linewidth,tex height=4cm,zoom=1]{}
+ \mrcdrawmap
+ \node[below,font=\fontsize{7pt}{7pt}\sffamily] at (mrcmap.south)
+ {\mrcmapattribution}; \mrcclipmap
+ \path[draw] (mrcmap.south west) rectangle (mrcmap.north east);
+ \mrcmarker{type=pin,position=61.22:-149.88,contents={Anchorage}}
+ \mrcmarker{type=pin,position=43.12:131.9,contents={Vladivostok}}
+ \end{tikzpicture}
+ \end{dispExample}
+
+ You cannot trust too much in figures from
+ \refCom{mrcprettymapscale},
+ \refCom{mrcprettymapwidth},
+ \refCom{mrcprettymapheight}, etc
+ for large and medium scale maps.
+ For small scale maps, these figures are worse and even misleading.
+ Better do not use them:
+
+ \tikzsetnextfilename{limit_small_scale_2}%
+ \begin{dispExample}
+ \mermapset{supply/source=opentopomap}
+ \begin{tikzpicture}
+ \mrcmap[type=reference,latitude=48.14,longitude=11.57,
+ tex width=\linewidth,tex height=6cm,zoom=2]{}
+ \mrcdrawmap
+ \node[below,font=\fontsize{7pt}{7pt}\sffamily] at (mrcmap.south)
+ {\mrcmapattribution}; \mrcclipmap \mrcdrawinfo
+ \end{tikzpicture}
+ \end{dispExample}
+
+
+%-------------------------------------------------------------------------------
+\clearpage
+\subsection{Zoom is not Scale}
+
+ Using the same zoom value for different latitudes can give completely
+ different scales. The following example for Oslo and Rio de Janeiro
+ at zoom 12 scales to 1:151000 and otherwise 1:277000.
+ \tikzexternaldisable
+
+ \tikzsetnextfilename{limit_zoom_scale_1}
+ \begin{dispExample}
+ \mermapsetsupply{source=stamen terrain, type=reference, zoom=12,
+ tex width=7cm, tex height=5cm}
+ \begin{tikzpicture}
+ \mrcmap[latitude=59.91,longitude=10.75]{oslo1} \mrcdrawmap
+ \end{tikzpicture}\hfill\begin{tikzpicture}
+ \mrcmap[latitude=-22.91,longitude=-43.20]{rio1} \mrcdrawmap
+ \end{tikzpicture}
+ \begin{center}\fontsize{7pt}{7pt}\sffamily\mrcmapattribution\end{center}
+ \end{dispExample}
+
+ Same example again, but with \refKey{/mermap/flex scale} which gives
+ 1:150000 for both cities and comparable maps.
+
+ \tikzsetnextfilename{limit_zoom_scale_2}
+ \begin{dispExample}
+ \mermapsetsupply{source=stamen terrain, type=reference}
+ \begin{tikzpicture}
+ \mrcmap[latitude=59.91,longitude=10.75, flex reference scale=150000,
+ tex width=7cm, tex height=5cm]{oslo2} \mrcdrawmap
+ \end{tikzpicture}\hfill\begin{tikzpicture}

+ tex width=7cm, tex height=5cm]{rio2} \mrcdrawmap
+ \end{tikzpicture}
+ \begin{center}\fontsize{7pt}{7pt}\sffamily\mrcmapattribution\end{center}
+ \end{dispExample}
+
+
+%-------------------------------------------------------------------------------
+\clearpage
+\subsection{Distances}
+
+There are at least three kinds of distance measures between two points
+on the map:
+\begin{itemize}
+\item Measure the distance with a ruler on the printed (or displayed) map
+ and multiply with the \refCom{mrcmapscaledenominator}.
+ Note that the map scale denominator is only (approximately) correct
+ for the map center.
+\item Compute the loxodromic distance, e.g. with \refCom{mrcstoreloxodistance}
+ which gives the (approximated) distance following a loxodrome.
+ On our Mercator map, this would be equal to the ruler method from above,
+ if the map scale would be constant.
+\item Compute the orthodromic distance, e.g. with \refCom{mrcstoreorthodistance}
+ which gives the (approximated) shortest distance following an orthodrome.
+\end{itemize}
+Apart from the approximate nature of the implementation, these distances
+are expected to be quite identical for large scale maps, but not for
+(very) small scale maps.
+

+
+As illustrated above, the script aided map definition is a process with
+several stages.
+
+\begin{itemize}
+\item Map Supply: \refCom{mrcsupplymap} is the replacement of the manual setup by
+ \refCom{mrcdefinemap}. Actually, it is quite similar to \refCom{mrcdefinemap}.
+ With \refCom{mrcsupplymap} directions for the following Python script
+ are formulated.
+\item Python Script: The script is executed by \refCom{mrcsupplymap} during
+ compilation. It does some coordinate system computations and downloads
+ map tiles from a Web server. Finally, it writes a map definition into
+ a file \meta{id}|.def|.
+\item Map Apply: \refCom{mrcapplymap} reads and applies the
+ map definition from \meta{id}|.def|.
+\item Map Drawing: Afterwards, the map can be drawn by \refCom{mrcdrawmap}
+ and other commands.
+\end{itemize}
+
+A map can be applied more than once, e.g. reused later in the document.
+If this is not needed, map supply and map apply can be combined by
+\refCom{mrcmap}.
+
+
+%-------------------------------------------------------------------------------
+\subsection{Script Activation}
+
+Remember to install Python beforehand, see \Fullref{sec:python}.
+
+\begin{docCommand}{mrcactivatescript}{}
+ Use this inside the preamble of your document to activate the
+ accompanying Python script.
+ Without this command, the script is not executed!
+ If the document is final (or the maps are final),
+ this line could be removed and the document
+ should be compilable without script.
+\end{docCommand}
+
+
+\begin{docMrcKey}{python}{=\meta{python}}{no default, initially |python|}
+ Names the Python~3 interpreter as \meta{python}. If your Python~3 interpreter
+ is not called |python|, but e.g. |python3|, then use
+ \begin{dispListing}
+ \mermapset{python=python3}
+ \end{dispListing}
+\end{docMrcKey}
+
+
+\clearpage
+%-------------------------------------------------------------------------------
+\subsection{Map Types}
+Currently, there are three methods provided how a map is computed by the
+accompanying Python script. The technical background is documented in
+\cite[Section~5]{Sturm:2020}.
+
+\begin{enumerate}
+\item \refKey{/mermap/supply/type}|=|\docValue{reference}:
+ \tcbsidebyside[sidebyside adapt=left,blankest,grow to left by=1cm]
+ {
+ \tikzexternaldisable
+ \begin{tikzpicture}
+ \useasboundingbox (0,0) rectangle (3,2);
+ \path[draw,fill=yellow!10] (0,0) rectangle (3,2);
+ \path[fill=red] (1.5,1) circle [radius=1mm];
+ \end{tikzpicture}
+ }{
+ The default method determines the map dimensions from a reference
+ position and given document map dimensions.
+ Also, a zoom level \refKey{/mermap/supply/zoom}
+ is required which relates to the Web Mercator map tile covering of the Earth.
+ A higher zoom level gives a growing number of smaller map tiles.
+ Alternative to the zoom level, a \meta{scale denominator} can be provided
+ by \refKey{/mermap/supply/flex area scale}, \refKey{/mermap/flex scale}
+ or \refKey{/mermap/supply/flex reference scale} which determines
+ the zoom level implicitly.
+ As default, the reference position is the center of the map, but can be
+ aligned at the map borders. This method is quite safe to use and could
+ be the preferred one for many applications like showing the neighborhood
+ of a route target.
+ Finding the best reference point for depicting a certain area could
+ be more tricky.
+ }
+
+\item \refKey{/mermap/supply/type}|=|\docValue{areafit}:
+ \tcbsidebyside[sidebyside adapt=left,blankest,grow to left by=1cm]
+ {
+ \tikzexternaldisable
+ \begin{tikzpicture}
+ \useasboundingbox (0,0) rectangle (3,2);
+ \path[draw,fill=yellow!10] (0,0) rectangle (3,2);
+ \path[draw=red,line width=0.5mm] (0.2,0.5) rectangle (2.8,1.5);
+ \end{tikzpicture}
+ }
+ {
+ The map dimensions are determined by an area with
+ latitude and longitude boundaries which is fitted into given
+ document map dimensions. The zoom level is computed accordingly
+ for a fixed document tile size or by \refKey{/mermap/supply/flex area fit}.
+ In any case, the map contains the target area plus some protrusion.
+ This method is also quite safe to use and may be
+ the preferred one for many applications like showing a map which contains
+ a bunch of markers (e.g. for locations of universities).
+ If the map borders are required to exactly meet the boundaries,
+ the third method can be regarded.
+ }
+
+\item \refKey{/mermap/supply/type}|=|\docValue{boundaries}:
+ \tcbsidebyside[sidebyside adapt=left,blankest,grow to left by=1cm]
+ {
+ \tikzexternaldisable
+ \begin{tikzpicture}
+ \useasboundingbox (0,0) rectangle (3,2);
+ \path[draw=red,line width=0.5mm,fill=yellow!10] (0.2,0.5) rectangle (2.8,1.5);
+ \end{tikzpicture}
+ }{
+ The most obvious method determines the map dimensions from
+ latitude and longitude boundaries. For this, a corresponding zoom level
+ \refKey{/mermap/supply/zoom}
+ is required which relates to the Web Mercator map tile covering of the Earth.
+ Alternative to the zoom level, a \meta{scale denominator} can be provided
+ by \refKey{/mermap/supply/flex area scale}
+ or \refKey{/mermap/supply/flex reference scale} which determines
+ the zoom level implicitly.
+ Note that a too high zoom level imposes the risk of downloading an unwanted
+ high quantity of map tiles resulting in a much too large document map.
+ Therefore, this most obvious method is \emph{not recommended} for the
+ beginner and may be explored after some experience.

+\subsection{Map Supply}
+
+\begin{docCommand}{mrcsupplymap}{\oarg{options}\marg{definition}}
+ The \meta{options} provide parameters for the Python~3 script to supply all
+ materials for a map.
+ All options share the common prefix |/mermap/supply/|.\par
+ The map is identified by\\
+ \meta{id}=\refKey{/mermap/definition prefix}+\meta{definition}\\
+ for later drawing.
+ This identifier \meta{id} has to be unique for the document.
+ It corresponds to generated files \meta{id}|.def|, \meta{id}|.md5|, and
+ possibly \meta{id}|.png|.
+ Do not use spaces or special characters like umlauts for \meta{definition}.
+ \par
+ If \refCom{mrcactivatescript} is used inside the preamble,
+ \refCom{mrcsupplymap} executes the Python~3 script, otherwise nothing happens.
+\end{docCommand}
+
+
+\begin{docCommand}{mermapsetsupply}{\marg{options}}

+\end{docMrcKey}
+
+\begin{docMrcKey}{supply/target}{=\meta{setup target}}{no default, initially |tiles|}
+ Defines the type of output for the Python~3 script. Feasible values are:
+ \begin{itemize}
+ \item\docValue{none}: No tiles are downloaded and no merged map is generated, just map computation.
+ This is the fastest method and needs no tile supplier.
+ \item\docValue{tiles}: Download map tiles from a tile map service (TMS) \refKey{/mermap/supply/url}.
+ Compilation of a document with map tile takes longer than compilation
+ with a merged map and transparency should not be used with tiles,
+ but the resulting document is smaller than a document with merged maps.
+ \item\docValue{mergedmap}: Download map tiles from a tile map service (TMS)
+ \refKey{/mermap/supply/url} and merge them into a single map picture.
+ This speeds compilation and allows transparency effects, but
+ the resulting document is possibly larger than a document with map tiles,
+ because map tiles often are optimized 8-bit image files while the merged
+ image is a 24-bit PNG file. Additionally, synergy effects of using the same map tiles
+ for different maps are lost.
+ Also, since the pixel map is clipped to full pixels, the resulting map
+ may differ (shift/size) from the more accurate tile representation by
+ one pixel.
+ \item\docValue{wmsmap}: Download a single map from a web map service (WMS)
+ \refKey{/mermap/supply/url}. Internally, the package treats a WMS like

+
+\begin{docCommand}{mrcapplymap}{\marg{definition}}
+ A map which is supplied by \refCom{mrcsupplymap} is applied
+ inside a |tikzpicture| environment by
+ \refCom{mrcapplymap} where \meta{definition} identifies the map.
+ \refCom{mrcapplymap} replaces a manual setup by \refCom{mrcdefinemap}.
+ The same map can be applied more than once inside a document.
+ Note that applying a map does not mean to draw the map, but to prepare
+ everything for drawing.
+\end{docCommand}

+
+\begin{docCommand}{mrcmap}{\oarg{options}\marg{definition}}
+ This is a combination of
+ \refCom{mrcsupplymap} with the given \meta{options}
+ followed immediately by \refCom{mrcapplymap}.
+ If \meta{definition} is left empty, an automated unique identifier is
+ inserted.
+ If a map is to be used just once, \refCom{mrcmap} may be preferred.

+\subsection{Map Tile Server}\label{sec:maptileserver}
+
+
+To use map tiles with this package you obviously need access to a map tile server.
+Thanks to all the many contributors to
+\href{https://openstreetmap.org/copyright}{OpenStreetMap},
+map data is free for everyone to use.
+\textbf{But, map tile servers based on OpenStreetMap are not necessarily free}.
+
+A list of online raster tile servers based on OpenStreetMap data is found here:\\
+\url{https://wiki.openstreetmap.org/wiki/Tile_servers}
+
+\begin{itemize}
+\item\bfseries I do not run a map tile server.
+\item I do not and cannot grant any permission to access a map tile server.
+\item I do not and cannot grant any permission to use map tiles in
+ private, academic, free, or commercial publications.
+\item All operators of map tile servers require to mention an attribution
+ for their maps.
+\end{itemize}
+
+The following option allows easy usage of very few selected tile servers.
+The tile server of \href{https://openstreetmap.org/copyright}{OpenStreetMap}
+is not included because of its
+\href{https://operations.osmfoundation.org/policies/tiles/}{Tile Usage Policy}.
+I am aware that the following list could be enlarged much more, but I do not
+want to add more to avoid any legal uncertainties.
+
+\begin{itemize}
+\item\bfseries I will remove an entry immediately, if the tile server operator
+ asks for it.
+\item\mdseries If \textbf{YOU} operate a tile server and you want an entry here, I would be
+ glad to add it to the following list.
+\end{itemize}

+\section{Orthodromes and Loxodromes}\label{sec:orthodromes}%
+
+A loxodrome is a curve which crosses all meridians with
+a constant angle. On Mercator maps, loxodromes are depicted as straight lines
+and can be drawn by simple \tikzname\ |path| elements.
+
+On a sphere, the shortest path
+from one point to another runs along an orthodrome where
+an orthodrome is a great-circle.
+
+The mathematical background and further information are found in \cite{Sturm:2020}.
+
+
+%-------------------------------------------------------------------------------
+\subsection{Orthodrome Drawing}
+
+\begin{docMrcKey}{samples}{=\meta{number}}{no default, initially |100|}
+ An orthodrome curve is approximated by a polygon trajectory with
+ \meta{number} pieces.
+\end{docMrcKey}
+
+
+\begin{docTikzKey}{mermap samples}{=\meta{number}}{style, no default}
+ \tikzname\ variant to set \refKey{/mermap/samples}.
+\end{docTikzKey}
+
+
+\begin{docCommand}{mrcdraworthodrome}{\oarg{options}\marg{lat1}\marg{lon1}\marg{lat2}\marg{lon2}}
+ Draws an orthodrome curve from a point with
+ latitude \meta{lat1} and longitude \meta{lon1}
+ to a point with
+ latitude \meta{lat2} and longitude \meta{lon2}.
+ This is a \tikzname\ path object where \meta{options} are
+ \tikzname\ settings for this path. There are two orthodrome pieces connecting
+ two positions (forming a great-circle). \refCom{mrcdraworthodrome} does
+ not necessarily choose the shorter one, see \cite{Sturm:2020}.
+ The drawn orthodrome is a spherical approximation instead of an ellipsoidal
+ one.

+\section{Routes}\label{sec:routes}%
+
+Routes are \tikzname\ |path| objects which can be drawn with the appropriate
+\tikzname\ macros and the coordinate system documented in
+\Fullref{sec:map_definition}.
+Nevertheless, in the following some alternatives are described which allow
+to specify a path by a sequence of points (\refCom{mrcpoint}).
+The idea is that such a sequence of points is exported by a third-party
+application for inclusion in a \LaTeX\ map, see \Fullref{sec:routes_gpx}.
+
+
+%-------------------------------------------------------------------------------
+\subsection{Route Path Definition}
+
+\begin{docEnvironment}{mrcroute}{\oarg{options}}
+ This environment creates a \tikzname\ |path| with given \tikzname\ \meta{options}.
+ The \meta{environment content} is a sequence of points made by \refCom{mrcpoint}.

+ ...
+ \end{mrcroute}
+ \end{dispListing}
+ Note that a map definition by \refCom{mrcdefinemap}, \refCom{mrcmap},
+ or \refCom{mrcapplymap} is needed before a route |path| can be drawn.\par
+ %A |path| can be closed by adding \docAuxCommand{pgfpathclose} as last entry

+\section{Scales and Sizes}%
+
+Inside a defined map several size values and scaling options are
+available. Please note that due to the nature of the Mercator projection and several
+simplifying assumptions all specifications for map scale, map width, map height,
+etc. are imprecise in the best case and even misleading in the worst case.
+They are suited for representative diagrams,
+but not for critical navigation purposes etc.
+
+\subsection{Map Sizes and Document Sizes}
+
+\begin{docCommand}{mrctexwidth}{}
+ \TeX\ length denoting the document width of the current map.
+\end{docCommand}
+
+\begin{docCommand}{mrctexheight}{}
+ \TeX\ length denoting the document width of the current map.
+\end{docCommand}
+
+\begin{docCommand}{mrcscale}{}
+ Scaling factor between map and real world.
+ A \TeX\ length given in |pt|, but stripped from that unit,
+ multiplied by \refCom{mrcscale} corresponds to a real world length
+ given in kilometers.
+ Note that this is \emph{not} the map scale.
+ Actually, it is reciprocal proportional to the map scale
+ and proportional to the map scale denominator, see \refCom{mrcmapscaledenominator}.
+\end{docCommand}
+
+\begin{docCommand}{mrctextokm}{\marg{length}}
+ Computes a given \TeX\ \meta{length} (with unit) into the corresponding
+ real world length in kilometers (without unit).
+ \begin{dispListing}
+ Map width: \mrctextokm{\mrctexwidth}\,km
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrctextomile}{\marg{length}}
+ Computes a given \TeX\ \meta{length} (with unit) into the corresponding
+ real world length in miles (without unit).
+ \begin{dispListing}
+ Map width: \mrctextomile{\mrctexwidth}\,mi
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrckmtotex}{\marg{number}}
+ Computes real world length \meta{number} in kilometers (without unit)
+ to a \TeX\ length (with unit).
+ \begin{dispListing}
+ % draw a circle with radius 20km
+ \draw (mrcpos) circle (\mrckmtotex{20});
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrcmiletotex}{\marg{number}}
+ Computes real world length \meta{number} in miles (without unit)
+ to a \TeX\ length (with unit).
+ \begin{dispListing}
+ % draw a circle with radius 20 miles
+ \draw (mrcpos) circle (\mrcmiletotex{20});
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrcmapscaledenominator}{}
+ Approximate map scale denominator.
+ \SI{1}{cm} on the map corresponds approximately to
+ \mbox{\refCom{mrcmapscaledenominator}$\cdot$\SI{1}{cm}} in the real world.
+ Do not confuse with \refCom{mrcscale}.
+ \begin{dispListing}
+ Map scale: 1:\mrcmapscaledenominator
+ \end{dispListing}
+\end{docCommand}
+
+
+\subsection{Pretty Size Output}
+
+
+\begin{docCommand}{mrcprettymapscale}{}
+ Approximate map scale given with three valid digits
+ with a representation like |1:1000|.
+ \begin{dispListing}
+ Map scale: \mrcprettymapscale
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrcprettymapwidth}{}
+ Approximate map width in kilometers (or meters) with three valid digits:
+ \begin{dispListing}
+ Map width: \mrcprettymapwidth
+ \end{dispListing}
+ To create a pretty printing to your own liking, you can do like the
+ following:
+ \begin{dispListing}
+ \newcommand{\myprettymapwidth}{\SI[round-mode=figures,round-precision=3]%
+ {\mrctextokm{\mrctexwidth}}{km}}
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrcprettymapheight}{}
+ Approximate map height in kilometers (or meters) with three valid digits:
+ \begin{dispListing}
+ Map height: \mrcprettymapheight
+ \end{dispListing}
+\end{docCommand}
+
+
+\begin{docCommand}{mrcprettymapresolution}{}
+ Approximate map resolution in dpi (dots per inch):
+ \begin{dispListing}
+ Map resolution: \mrcprettymapresolution
+ \end{dispListing}
+\end{docCommand}
+
+\begin{docCommand}{mrcprettytilesize}{}
+ Approximate tile size inside the document (\TeX\ size) in millimeters:
+ \begin{dispListing}
+ \TeX\ tile size: \mrcprettytilesize
+ \end{dispListing}
+\end{docCommand}
+
+

+\subsection{Scale Bars}
+
+
+\begin{docCommand}{mrcdrawscalebar}{\oarg{options}}
+ Draws a scale bar according to the given \meta{options}.
+ All \meta{options} share the common prefix |/mermap/scalebar/|.
+ The most essential option is the \emph{width} of the scale bar.
+
+ \tikzsetnextfilename{scales_scalebar1}

+
+ The size, position, and appearance of the scale bar can be customized by
