Mobile GIS
Mobile GISrefers to an integratedsoftware/hardware frameworkforthe access of geospatial data andservices through mobile devicesviawireline or wireless networks(Tsou,
2004).
(Notebooks , PDA, Tablet PC, Pocket
PC, etc .)
WHY mobile GIS
Field works:data collection and validationprocess, coupled with GPS and wirelesscommunications.
Real-timeupdate / change
GPS integration.

How GPS and mobile information systems have
enhanced GIS
Ability to define data to be collected prior to
field work
Data dictionaries
Ability to quickly and accurately collectinformation
Location and attribute information
Various levels of positional accuracy
Error checking on attribute entry Compatibility with GIS and CAD systems

Ways GPS can be used in GIS
Data collection
Recording something, somewhere
What do I have?
What condition is it in?
Data maintenance
Verifying something, somewhere
Is the information I have correct?
Data use Current and accurate data to
support decision making

Wireless Local Area Network (WLAN)
Wi-Fi or WiMAX Technology
Different from cellular phone communication (CDMA, GPRS)Fast Transmission Speed, Good for GIS applications (large size of data/images)
Wi-Fi-- MIMO (multiple input multiple output). Short distance: 300 feet.
WiMAX(available in late 2006) (Wireless Metropolitan Area Network
(WMAN). 30 75 Mbps, 4 6 miles
