What’s a Car Navigation System
Route Guidance
Turn by Turn Maneuver
ex. Turn right 100m ahead
Maneuver List
Simulation of the route
Inform Guidance points
ex. Intersection,Entrance/Exit,Railroad crossing,
Estimate Arriving Time/Remain Distance/Direction of the Destination

What’s a KIWI
KIWI is the best format for Car Navigation DataBase.
- It is only ‘Open PSF’ for car navigation.
- It applies the experience of all Japanese system maker.
- It is light and small size than their proprietary format.
- It is used by all Japanese system maker.
- It is able to contain the temporal information of object.
- It is able to add every country’s requirement.
2003.1.23 KIWI-W consortium
What’s a KIWI
It contains
- Database Control data
- Map data
- Guidance data
- Road network(Route Planning) data
- Search / Index data
- Picture data/ Voice data
- Parameter data
- Corresponding to Traffic information data
2003.1.23 KIWI-W consortium
- Database Control data
Volume/Allocation/Parcel/Region
- Map data
Road data: Node/Link/Shape
Background data: Polyline/Polygon/Point
Name data: Road/background/place/landmark
- Guidance data
intersection name/street name/district name/ /guide spot/road structure/building&facility
