Why Internet Mapping? Flexible Information Access / Exchange (End-Users only need a web browser) Why Internet Mapping? Flexible Information Access / Exchange (End-Users only need a web browser) Information Sharing and Integration (Access multiple Internet Map Servers at the same time– local governments, USGS, EPA, Census Bureau, etc. ) Real-time Information Update and Distribution Gather data from client sides (polices, firefighters), distribute updated data from server sides (control centers)

Mobile GIS • Mobile GIS refers to an integrated software/hardware framework for the access 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 work: data collection and validation process, coupled with GPS and wireless communications. – Real-time update / change – Global Positioning System (GPS) integration.

Wireless Local Area Network (WLAN) Wi-Fi or Wi. MAX Technology Different from cellular phone Wireless Local Area Network (WLAN) Wi-Fi or Wi. MAX Technology Different from cellular phone communication (CDMA, GPRS) Fast Transmission Speed, Good for GIS applications (large size of data/images) • Wi-Fi (802. 11 b, 11 Mbps, 2. 4 Ghz), Wi-Fi 5 (802. 11 a, 54 Mbps, 5 GHz). 802. 11 g, and 802. 11 n (up to 200 Mbps) -- MIMO (multiple input multiple output). Short distance: 300 feet. • Wi. MAX (available in late 2006) 802. 16 d, 802. 16 e (Wireless Metropolitan Area Network (WMAN). 30 – 75 Mbps, 4 – 6 miles
