Combining Web-based GIS and Wireless Mobile GIS for Wildfire Recovery and Watershed Management by Dr. Ming-Hsiang (Ming) Tsou Phone: Fax: The Department of Geography, San Diego State University SDFRN Workshop April 13, 2005, San Diego Natural History Museum

Web-based GIS (Internet GIS) San Diego State University Internet Map Server (ArcIMS) Web Server (map.sdsu.edu Internet Client (Web browser) + Java applets Client (Web browser) + IMS Viewer Client (Web browser) Regional Database (GIS) ServerClient The Network is the Computer The Internet is Your GIS.

San Diego Wildfire Provide Easy and Interactive Access (Web browser) to Geospatial Information

Spatial Query and Display Functions (ESRI ArcIMS examples) combining census data and remote sensing images.

Mobile 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.

Mobile GIS Architecture

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 (802.11b, 11Mbps, 2.4 Ghz), Wi-Fi5 (802.11a, 54Mbps, 5GHz) g, and n (up to 200Mbps) -- MIMO (multiple input multiple output). Short distance: 300 feet. WiMAX (available in late 2006) d, e (Wireless Metropolitan Area Network (WMAN). 30 – 75 Mbps, 4 – 6 miles

Wireless Mobile GIS Integration Prototype Testing (2003 at MTRP) (Notebook Web Server (IIS) + ArcPAD + Blue tooth GPS + Wi-Fi )

User Scenario: Environmental Monitoring and Management Mission Trail Regional Park (short movie) 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. (Link to the movie MTRP.wmv)

Real Time GIS for Emergency Response Real Time GIS for Emergency Response (NASA REASon Project Example) REASoN Project

Metadata/ Data Portal

Real-time Data Update from Pocket PC (ArcPAD) to Internet Map Server (ArcIMS) Submit new polygons (Hot-zones) from Pocket PC to Internet Map Server (ArcIMS) via Wi-Fi channel. Wireless Communication

Real-time Mobile GIS with Real-time Tracking Server ESRI ArcIMS Tracking Server (beta-version) Dynamic Display the location of in-field Agents (Park rangers, Fire fighters, etc.)
