Data
A good router relies on good data and the
OpenStreetMap
data is a good source. There are however a number of things that need to be
considered about
the data used.
Tagging
In addition to the raw data the way that are tags are used is also important.
With Routino the
tagging rules
are contained in a configuration file and can easily be customised to change the
interpretation of each tag.
Program Usage
There are four programs that make up this software, two create the routing
database and use the information in it and the other two perform additional functions.
Full instructions
for using the four programs are provided.
Configuration Files
When the programs are run they read in one or more
configuration files.
These files contain information about the routing preferences (types of highways,
preferred speeds etc), tagging rules and translation information for the outputs.
Output Files
The final result of running the router is one or more
output files
that contain the calculated route.
Numerical Limits
When processing data there are
numerical limits for the
range of data identifiers that can be handled and the size of the database.
Algorithm
The
algorithm that is used by
Routino takes the OpenStreetMap data and creates a local database of the
important information for rapid routing.
Installation
The Routino source code comes with a set of files that can be used to create
a working server very easily. The full information about
installation describes how
to compile the programs and install them on UNIX-like systems such as Linux.
MS Windows Installation
Routino can also be compiled and used on Microsoft Windows systems (with some
limitations). There are specific
MS Windows installation
instructions describing how to compile the programs.
Library
The Routino routing algorithm is also available as a
shared library
that can be linked with other programs to allow routing from within them.
