Transition of car navigation in Japan
• In 1991 Released Car navigation system by
various manufacturers
– Adoption of GPS and Gyro sensor
– From single purpose to multi purpose → The rise of
commercial items

Birth of Format
• Expansion of car navigation market
• Expectation of entering into the navigation
market by Audio makers which have no map
data
• Standardization of map disc, and entry the
navigation market with map disc provided by
map maker
• Birth of Naviken Format Ver1.0 in 1988
• After adding more function, birth of Ver2.1 in
1995

Intensification of functional race
• Quantitative race
– Map
• 1-10 thousandth scale model
of the whole country
• Adoption of foot prints
– 1400 cities
– Search for destination
• Search by phone number
– Corporation 10 million cases
– Individual 60 million cases
• Search by address
– 26 million cases

Alternation of Map disc format
• The format needs to be changed for
corresponding to upgrade.
• Naviken S Format Ver2.2
• The function which stands out from the rest is
required in order to overcome in market
competition.
– The format is not compatible on each year.

Increase of kinds of maintained version
• Map data needs to be maintained every year.
• The kinds of maintained version run up to one hundred and
dozens of kinds.

Limits of Naviken format
• Correspondence to upgrading reaches the limit.
– No expandability.
– The data format depends on the facility of the navigation
system.
• Compatibility of Naviken disc disappears.

Birth of Kiwi format
• The time of creation of industry standard format
– Correspondence to sophisticated navigation system
– Expandability
• Foundation of Kiwi-W Review committee in 1996
– 17 companies concerned in car navigation system
participate.
– Disclosure of X format from Xanavi
– Review of standard format
• Kiwi Ver1.1 was completed and estimated by demonstrative
experiment in 1998 .

Summary of Kiwi format
• Explanation of summary of the format
The name “Kiwi” was derived
from the fact the format had
been deliberated as
International standardization
at ISO meeting in Sydney.

Kiwi format aims…..
• To describe the real world
• To speed-up of data reference
• To compress the volume of the data
• To magnify the expandability
• To enlarge the field of application

Speed-up of Data Reference
• Main map data (parcel)
– Kiwi format refers to the data in a constant area
• Route planning data (region)
– Kiwi format refers to the data of wide area as much
as possible
• Hierarchical structure
– Kiwi format quickly refers to the data which exist
between one level and another, or which exist
nearby area
© 2002 Kiwi-W consortium

17.

Main Map Data (Parcel)
• They are used for Map-display, Location, and
Route guidance
• The area is divided by rectangles (parcel)
• Data has Hierarchical structure

Compression of the Volume of the Data
• Data management by the size of data
– Kiwi format sets the fixed size for each data block
and manages whole size of the data
• Data management by flags
– Kiwi format manages the existence of fluid data by
flags which correspond to bits.
• Multi link structure
– Kiwi format integrates the roads which have same
attribute, and describe the existence of a
intersection.

The Expandability of the Data
• The expandability of basic data
– Kiwi format prepares the expanding part so that expansion
may not have any effect on the data reference
• Kiwi format manages the data by the number of elements and
the volume of the data
• Kiwi format controls the expansion by the flags which correspond
to the bits
– The expandability enables Kiwi format to expand in the future
and to store the individual data by each manufacturers
• The structure of file
– Kiwi format enables each manufacturers to store the individual
data.
