The goal of this package is the simplest possible provision of
map images (OpenStreetMap, Google Maps and Google Street View 
are supported). In the simplest case, it is is sufficient to
specify an address.. The package loads the map using the
\write18 feature, which you must activate to use this package.
The image will be downloaded by an external Lua script. You
can use this script also from the command line.

Changes in v1.11:

* Requests to Google Maps' Static Image API are no longer free

	added an API key, which allows 
  
	2000req/day for Google Maps and
	1000req/day for Google Street View

 -x  specify a xsize (600)

 -y  specify a ysize (400)

 -S  short form to specify a size, e.g. 600,400 (osm) or 600x400 (gm)

 -s  specify a scale factor in the range 1692-221871572 (osm) or
     1-2 (gm)

 -z  specify a zoom in the range 1-18 (osm) or 0-21 (17) (gm)

 -t  specify map type {map|sathyb} (map) (osm) or
     {roadmap|satellite|hybrid|terrain} (roadmap) (gm)

 -i  specify image type {png|gif|jpg|jpeg} (png) (osm) or
     {png|png8|png32|gif|jpg|jpg-baseline} (png) (gm)

 -c  specify icon color (yelow_1) (osm) or (blue) (gm)
     see: http://open.mapquestapi.com/staticmap/icons.html
          https://developers.google.com/maps/documentation/staticmaps/#MarkerStyles

 -n  specify the icon number (1)

 -o  specify output basename without file extension (getmap.IMAGETYPE)

 -q  quiet; no output!

 -v  prints version information

 -h  prints help information

 gm mode only:

 -L  specify the language of map labels (xx language code (en,de,fr,...))

 -M  specify markers; see:
     https://developers.google.com/maps/documentation/staticmaps/index#Markers
     e.g.: &markers=size:mid|color:blue|label:1|address or more of these
     location and zoom will be ignored if used!

 -C  specify center of the map

 -V  specify a list of visible locations (loc1|loc2)

 -P  specify path from location to location
     e.g.: &path=weight:7|color:purple|loc1|loc2

 -p  specify a file holding the path specification
     (maybe needed for encoded polylines)

 gsv mode only:

 -H  specify heading (view) (0) (0 -- 360) (east: 90, ...)

 -T  specify the pitch (angle) (0) (-90 -- 90)

 -F  specify horizontal field of view (90) (0 -- 120)
     The field of view is expressed in degrees and a kind of zoom!

 gpx2epl, gps2epl and gpx2gps mode only:

 -G  specify the gpx or gps file

 kml2epl and kml2gps mode only:

 -K  specify the kml file

 gps2gps mode only:

 -B  specify the bound for reducing way points (default: 0.1)

% \Headline{Abstract}
% \begin{abstract}
% The goal of this package is the simplest possible provision of
% map images (OpenStreetMap, Google Maps and Google Street View 
% are supported). In the simplest case, it is is sufficient
% to specify an address. The package loads the map using the
% \cmd\write18 feature, which you must activate to use this package.
% The image will be downloaded by an external Lua script. You can 
% use this script also from the command line.
% \end{abstract}

% \renewcommand*{\abstractname}{Acknowledgment}
% \begin{abstract}
% I want to thank Norbert Preining, who did most of the recoding of \texttt{osmimage}
% (\texttt{Bash} $\rightarrow$ \texttt{Lua}). Moreover many thanks to Taco Hoekwater, Akira Kakuto,
% Reinhard Kotucha and Heiko Oberdiek for their valuable contributions.
% Finally, I want to thank Doug Currie for helping me to implement the algorithm
% for encoded polylines in Lua.

% \section{Options}
% The following options can be used as package options with global scope,
% as well as options for the \cmd\getmap\ command with local scope!
% \subsection{General options}
% \subsubsection[\texttt{mode}]{\texttt{mode (\underline{osm}\textbar{}gm\textbar{}gsv})}
% This option sets the mode, that is the source of the images. OpenStreetMap, Google Maps or Google Street View!
% Please note that -- if used as local option (mixed modes) -- the default values of the \texttt{scale}, \texttt{zoom}, \texttt{type} and \texttt{color} 
% options for the respective mode are reset to guarantee correct download URLs!
% \subsubsection[\texttt{inputencoding}]{\texttt{inputencoding}}
% This option specifies the input encoding of your file.
% The download script requires the strings encoded in utf8.
% For the safe conversion the input encoding of the file is required.
% Normally, you don't have to specify an encoding.
% The package tries to evaluate the encoding given to \package{inputenc} or assumes utf8.
% Usually that should work.
% \subsubsection[\texttt{overwrite}]{\texttt{overwrite (\underline{false}\textbar{}true)}}
% With this option, you can specify whether the image should be downloaded in any case.
% By default, the option is set to \texttt{false} in order to save bandwidth and compilation time.
% Nevertheless a check is performed on the existence of the image and the
% image will be downloaded, if it is not present.
% In the case of \texttt{true}, the image will be downloaded anyway!
% BTW, \texttt{overwrite} is equivalent to \texttt{overwrite=true}.
% \subsubsection[\texttt{file}]{\texttt{file (\underline{getmap})}}
% This \marginpar{\begin{gmbox}changed default value to \texttt{getmap} in version 1.2!\end{gmbox}}
% option allows you to specify the name of the image (without extension).
% \subsection{\texttt{osm} mode}
% \subsubsection[\texttt{key}]{\texttt{key (\underline{Fmjtd\textbar{}luur20u22d,75=o5-9aylh6}})}
% In \texttt{osm} mode, the download script requires a key in order to use the service of MapQuest.
% By default, it uses a key, which is registered for \package{getmap}.
% But you can register and use your own key with this option.
% The default key is stored in \texttt{getmap.cfg}. You can copy this file to your local \TeX\ tree
% and store your own key there\footnote{Mapquest will deliver an url-encoded key, which must
% be decoded to ASCII, e.g. by \href{http://urldecode.org/}{Url decode}}!
% This file will be found after running \texttt{texhash}!
% \subsubsection[\texttt{scale}]{\texttt{scale (\underline{3385}})}
% This option allows you to specify a display scale for the map image in the range of
% 1692 -- 221871572. You will not necessarily see a difference between 5000 and 5500.
% A scale value of 3385 corresponds to a zoom level of 17.
% \subsubsection[\texttt{zoom}]{\texttt{zoom}}
% This option allows you to specify a zoom level in the range of 1 -- 18.
% This option overwrites a possibly given scale.
% \subsubsection[\texttt{xsize}]{\texttt{xsize (\underline{600})}}
% This option specifies the width of the map in pixels.
% If \marginpar{\begin{gmbox}changed default value to \texttt{600} in version 1.2!\end{gmbox}}
% you only want to slightly increase or decrease the map extract,
% you should adjust the size of the map. You still have full control over the size of
% the map in the document with the options of \cmd\includegraphics. (max: 3840)
% \subsubsection[\texttt{ysize}]{\texttt{ysize (\underline{400})}}
% This option specifies the height of the map in pixels. (max: 3840)
% \subsubsection[\texttt{imagetype}]{\texttt{imagetype (\underline{png}\textbar{}jpeg\textbar{}jpg\textbar{}gif)}}
% This option allows you to specify the type of the image.
% \subsubsection[\texttt{type}]{\texttt{type (\underline{map}\textbar{}sat\textbar{}hyb)}}
% This option specifies the type of the map.
% It seems as if there would be only a few regions of Mother Earth,
% for which satellite and hybrid images are available.
% \subsubsection[\texttt{color}]{\texttt{color (\underline{yellow\_1})}}
% This option specifies the color of the marker. Possible colors:
%
% \href{http://open.mapquestapi.com/staticmap/icons.html}{http://open.mapquestapi.com/staticmap/icons.html}
% \subsubsection[\texttt{number}]{\texttt{number (\underline{1})}}
% This option specifies the number of the marker.
% \subsection{\texttt{gm} mode}
% From 2018 on, Google Maps APIs are no longer accessible without a key.
% Since \texttt{getmap.sty} is an open source project, it is impossible to finance an infinite number of requests, but Google allows a limited number of requests for \enquote{free}.
% As a consequence, the following restrictions arise:
%
% \begin{tabular}{rl}
% Google Maps & 2000 requests per day \\
% Google Street View & 1000 requests per day
% \end{tabular}
% \subsubsection[\texttt{scale}]{\texttt{scale (\underline{1})}}
% For the free version of Google Maps the image size is limited to 640x640.
% You can set \texttt{scale} to a value of 2, to get exactly the same map in doubled size in pixels.
% \subsubsection[\texttt{zoom}]{\texttt{zoom} (\underline{17})}
% This option allows you to specify a zoom level in the range of 0 -- 21.
% \subsubsection[\texttt{xsize}]{\texttt{xsize (\underline{600})}}
% This option specifies the width of the map in pixels.
% If you only want to slightly increase or decrease the map extract,
% you should adjust the size of the map. You still have full control over the size of
% the map in the document with the options of \cmd\includegraphics. (max: 640)
% \subsubsection[\texttt{ysize}]{\texttt{ysize (\underline{400})}}
% This option specifies the height of the map in pixels. (max: 640)
% \subsubsection[\texttt{imagetype}]{\texttt{imagetype (\underline{png}\textbar{}png8\textbar{}
% png32\textbar{}gif\textbar{}jpg} (progressive)\texttt{\textbar{}jpg-baseline} (flat))}
% This option allows you to specify the type of the image.
% \subsubsection[\texttt{type}]{\texttt{type (\underline{roadmap}\textbar{}satellite\textbar{}hybrid\textbar{}terrain)}}
% This option specifies the type of the map.
% \subsubsection[\texttt{color}]{\texttt{color (\underline{blue})}}
% This option specifies the color of the marker. Possible colors:
%
% black, brown, green, purple, yellow, blue, gray, orange, red, white or in hex format \texttt{0x3399FF}
% \subsubsection[\texttt{number}]{\texttt{number (\underline{1})}}
% This option specifies the number of the marker. Google Maps also allows uppercase letters: [A-Z]!
% \subsubsection[\texttt{language}]{\texttt{language} (\underline{en})}
% This option specifies the language of the map labels.
% Of course, not all languages are supported for all countries.
% At least, english and one of the national languages should be supported.
% Possible option values: en, de, fr, es, it, fi, ...
% \subsubsection{\texttt{markers}}
% This option allows you to set more than just the standard marker, which will no longer be used!
% You don't have to specify an address, as Google Maps will deliver an image with all markers on the map.
% Nevertheless, you can specify an address, which will define the center of the map.
% This option expects one or more URL parameters like:
%
% \texttt{\&markers=size:mid\textbar{}color:blue\textbar{}label:S\textbar{}loc1\textbar{}loc2\textbar{}...}

% \section{Command(s)}
% \subsection[\textbackslash{}getmap]{\cmd\getmap}
% With the \cmd\getmap\ command\margcs{\cmd\getmap\oarg{options}\marg{address}} you can download
% a map, if you enable \cmd\write18 (TeXLive: \texttt{-shell-escape}, MiKTeX: \texttt{-{}-enable-write18}).
% This is only necessary if you actually download an image.
% You can use the options described above to specify the properties of the downloaded image.
% After executing the command, the image is available in the current working directory!
%
% In the simplest case, you only need an address, a POI or geographic coordinates
% (\texttt{latitude,longitude}) to download the map. \marg{address} must be fully expanded and must not contain macros!
% By default, the image is saved under the name \texttt{getmap.png}!
% If you need only one map (e.g. the office of Dante e.V.) in your document, it can be as simple as:
%

% \section{The \texttt{getmapdl} Lua script}
% Basically, the \texttt{getmapdl} Lua script downloads static map images
% depending on command line options and allows to parse \texttt{kml}, \texttt{gpx} and
% \texttt{gps} (a plain list of geographical coordinate pairs \texttt{(latitude,longitude)}
% on each line) files and outputs \texttt{gps} or encoded polylines (epl).
% The script offers the following modes (\texttt{-m}):
% \begin{description}
% \item[osm] downloads a static map image based on OpenStreetMap data
% \item[gm] downloads a static map image based on Google Maps data
% \item[gsv] downloads an image based on Google Street View data
% \item[kml2epl] parses a \texttt{kml} file and outputs geographical coordinates of places and
% encoded polylines (\texttt{epl}) for routes and lines  to \texttt{STDOUT}
% \item[kml2gps] parses a \texttt{kml} file and outputs geographical coordinates
% \item[gpx2epl] parses a \texttt{gpx} file and outputs encoded polylines

% This encoded polyline can be used for the \texttt{path} or \texttt{pathfile}
% option of \cmd\getmap.
% \section{How to define routes}
% Routes are described by so called encoded polylines and can be used with
% \texttt{enc:polyline\_data} as location specifier in a \texttt{path}.
% This string can contain all sorts of troublesome characters for \LaTeX{}.
% \cmd\getmap\ can deal with them, with the exception of curly braces!
% These will break your \LaTeX{} document. As a work-around, use the \texttt{pathfile} option.
% Please note that the length of the URL is limited to 2048 bytes. So, there's
% no way to support extreme long paths!
% \subsection{OpenStreetMap}
% OpenStreetMap does not offer routing service directly, but you can
% use an OpenStreetMap based route service\footnote{\href{http://maps.openrouteservice.org}{http://maps.openrouteservice.org}}
% to create your route and export it to a \texttt{gpx} file\footnote{This also means that you can visualize your own routes tracked with hardware or a software app!}.
% It's basically a xml-packaged list of geographical coordinates.
% You can use the \texttt{getmapdl} script to convert a route to encoded polylines, e.g.
% a pedestrian route from Berlin Central Station to Brandenburg Gate:

% \subsubsection{Long routes}
%
% Long routes are defined by a huge number of way points, but the URL length
% is limited to 2048 bytes. The following \href{https://bitbucket.org/kleberj/getmap/downloads/MucBer.kml}{example}\footnote{https://bitbucket.org/kleberj/getmap/downloads/MucBer.kml}
% (Stachus, Munich $\rightarrow$ Brandenburg Gate, Berlin) consists of more
% than 6000 way points. A created polyline would hugely exceed the URL length limit!
%
% After transfering the \texttt{kml} file into a \texttt{gps} file, you can use
% the \texttt{gps2gps} mode of \texttt{getmapdl} to reduce the number of
% way points by a given bound. It takes a new pair of \texttt{gps} coordinates
% only if the difference of latitude or longitude is larger than the given bound!
% Finally, you can use the new \texttt{gps} file to create an encoded polyline.
