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 ２００３．１．２３ KIWI-W consortium What’s a Car Navigation System Address Location Address search Place name search the coordinate search Map code search Service/POI Category/Genre search (TM) Facility search Surrounding search Phone number search Postal code search ２００３．１．２３ KIWI-W consortium 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 What’s a KIWI - Database Control data Volume/Allocation/Parcel/Region -
