Location based services answer the call Where
am I, Where is it, Whats around me, Whats
around it and How do I get there.
5
A location based service would determine location
by using one of several technologies for
determining position, and use this location to
provide a personalised application.
6
Spurred on by the demands of technology for
ever-increasing, feature rich applications and
content.

• Call centres
• Emergency services
• Full service navigation
• Fleet and logistics management
• Vehicle and asset tracking
• Web services and
• Business planning and market intelligence.

8
One of the key ingredients to success in the
efficacy of location-based services. geographic
information and electronic mapping data used to
power the application.

Maps and map-like forms have served as both
organisational structures for the location of
human events and navigational aid for travellers
since the dawn of time.
10
We were able to project mapping information into
the digital era by leveraging 50 years of our
mapping research and production in paper-based
products.

Using satellite technology, it allows the
operator to track an entire fleet and check the
precise status and location of each vehicle
24-hours a day, 365 days per year, from anywhere
on the planet.
30
Portable and wireless devices such as PDAs and
mobiles are now able to offer navigation
capabilities enriched with an ever increasing
range of location based products.
31
On-board, factory fitted devices
32
Off-board devices such as PDAs and Pocket PC's 
33
And mobile applications via a mobile phone.
34
VEHICLE AND ASSET TRACKING Stolen vehicle
recovery operators are successfully using
location and geo-referenced data as visual tools
to locate and recover vehicles and assets.
35
Businesses are now able to make decisions based
on exceptions such as a vehicle having left or
entered certain areas, idle times and stationary
periods.
