2. Importance of Location
Information
• Cannot navigate by visually scanning
environment
• Limited access to what is around you
• Dependant on others for directions or
descriptions

3. Benefit of GPS and
electronic maps
• Due to mainstream popularity, maps
and millions of Points of Interest are
in electronic format
• Access to information = Ability to
independently navigate
• Ability to determine where you are,
what is around you, and how to get
to a destination.

I am in control

• Average accuracy 9 m (30 ft) or 3
m (10 ft) with WAAS/EGNOS

multiple directions. Decrease
accuracy in urban canyons
