Mobile GISMobile GIS

• Mobile GIS refers to an integrated software/hardware framework for the access of geospatial data and services through mobile devices via wireline or wireless networks (Tsou, 2004).

(Notebooks, PDA, Tablet PC, Pocket PC, etc.)

WHY mobile GIS – Field works: data collection and validation

process, coupled with GPS and wireless communications.

– Real-time update / change– GPS integration.

Wireless Local Area Network (WLAN)Wireless Local Area Network (WLAN)

Wi-Fi or WiMAX TechnologyWi-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 (802.11b, 11Mbps, 2.4 Ghz), Wi-Fi5 (802.11a, 54Mbps, 5GHz).

802.11g, and 802.11n (up to 200Mbps) -- MIMO (multiple input multiple output). Short distance: 300 feet.

• WiMAX (available in late 2006) 802.16d, 802.16e (Wireless Metropolitan Area Network (WMAN). 30 – 75 Mbps, 4 – 6 miles

Movies shot before the 2003 Wildfire.

After the Wildfire, another testing was conducted by helping the park ranger to evaluate the damages of wildfire and landform changes.
