== Generating turn-by-turn directions ==

[[PageOutline]]

=== Turn type ===
The turn type depends mostly on the turn angle.

Angle ranges are currently based on values from the [http://code.google.com/r/robertvoigt-monav/source/browse/client/instructiongenerator.h?name=permaroute Monav permaroute branch].

==== 8° < angle <= 45° ====
Turn slightly left

==== 45° < angle <= 135° ====
Turn left

==== 135° < angle <= 172° ====
Turn sharply left

==== 172° < angle <= 188° ====
Make a U-turn

==== 188° < angle <= 225° ====
Turn sharply right

==== 225° < angle <= 315° ====
Turn right

==== 315° < angle <= 352° ====
Turn slightly right

==== 352° < angle <= 8°  ====
Head straightforward

=== Compiling without GUI ===
To compile the Monav routing daemon, run this:
{{{
qmake CONFIG+=release DEFINES+=NOGUI monavroutingdaemon.pro && make
}}}

'''NOTE:''' The [http://code.google.com/p/monav/wiki/CompileGuide Monav compile guide] is wrong as it uses the correct syntax is ''NOGUI'' not ''nogui''. If ''nogui'' is used, the option does nothing and Monav still tries to compile the GUI components.
=== Routing data ===
Data from [http://monav.openstreetmap.de/] have a combined size of about 45 GB and are slightly outdated (April 2011).

Monav has its own map data repository - might be a good idea to ask them for their map generation script.

=== Compiling the Monav preprocessor ===
Compiling the current repository master branch is problematic due to some weird Mapnik dependencies.
