Roadmapper preliminary homepage
Roadmapper is the name of a project which goal it is to
create a fully Open Sourced travel-assistant. Roadmapper
consists of various pieces of standard hardware and (fully Open
Sourced) software and data.
Roadmapper bases on standard PC hardware and other
standard hardware components, like radio, mobile phone and a
GPS receiver. It receives data from hardware inside your
vehicle, e.g. GAL pulses from your speedometer and signals
from your gearbox, oil-pressure sensor, on-board-computer etc.
Roadmapper will be able to process various dataformats,
like RDS, SMS and (Open Source) digital maps on CD and
Roadmapper can be used for various tasks, amongst them:
- navigation - it enables you to find your way using a map and/or
spoken directions, and additionaly uses a unique 3 dimensional map
to show you where you are and which obstacles there may be on your way.
It will inform you about traffic jams, detours, bad weather,
speedlimits and more.
- fleet-control - this enables (authorised) people to find out where
you are annex have been;
- theft-alert, car-alert - not only will your car be able to honk
and beep if somebody moves it or breaks in to it; additionally the
system will inform the outside world about it's location on a regular
basis too. This enables easy retrieval of your property;
- automated cruisecontrol - you car is constantly informed about the
the (current) maximum speed limit on a certain road, and about
radar-posts, control-loops in the road etc. - it will adjust
your speed accordingly. Also, it may be connected to radar-detection
equipment and/or laser detection equipment (note: in as far this is
allowed in your country);
Roadmapper is a bi-directional system: it is able to send and
receive messages to and from various hardware- and software systems.
It uses a standardized, open messaging format named Roadmapper
Universal Messaging (RUM). RUM messages are handled by a set of
(software-)modules. These modules in turn communicate with the
various hardware components. RUM is able to use encryption and
has authentication mechanisms built-in.
E.g. a RUM message could be sent to your car, originating from
your dealer. Of course, the dealer would need to have your
permission to send you this type of messages, and you, and only
you, are in control of who is allowed to send/receive data
to and from your Roadmapper box.
Say, the dealer has permission to read out the values stored in
your car's board computer. Your car would transmit these, using
RUM encryption/authentication, the dealer's computers would decrypt
the data and analyze it. Perhaps they will send you a RUM message
to inform you that you should visit the garage. Of course, your PDA
will be informed too and the route to the garage is automatically
calculated by the navigator in your Roadmapper box.
The same messaging system can be used to update the digital maps or to
inform you about traffic jams and bad weather. They can be used
to send you e-mail's too. And RUM enables you to sent messages
yourself: peer-to-peer or to (sub-)groups of Roadmapper users
e.g. to inform them about traffic jams, speed-traps etc, or simply
to arrange a meeting during lunch. Gateways between e.g. Teletekst
and RUM, RDS and RUM and e-mail and RUM are foreseen (and probably
there will be many more).
The Roadmapper team will meet for the first time somewhere during
this summer. Initiators are Henk
Klöpping and Dirk-Jan Faber.

About the NMEA 0183 Version 2.0 standard, used by a lot of GPS equipment
GPS Manager (GPSMan) is a graphical manager of GPS data that makes possible the preparation,
inspection and edition of GPS data in a friendly environment. GPSMan supports communication and real-time logging with both Garmin and Lowrance receivers and accepts
real-time logging information in NMEA 0183 from any GPS receiver.
Open Source GPS software -
The software available is the Linux GPS receiver software based on the Qt toolkit. This provides
for simple logging of a journey, replay of a logged journey, a real-time moving map display and the ability to
add and edit your own maps and features. For copyright reasons this software does not come bundled with a usable
set of maps. The current release level is 1.0 and the gzipped archive is approximately 1.5MB including a fully
working binary and one sample map.
