Why Internet Mapping? Flexible Information Access / Exchange (End-Users only need a Web browser) ( 便捷的資訊取得 / 交換 ) Information Sharing and Integration ( 資訊分享及整合 ) (Access multiple Internet Map Servers at the same time– Local governments, USGS, EPA, Census, etc.) Real-time Information Update and Distribution Gather data from ( 即時資訊更新及發布 ) client sides (polices, firefighters), Distribute updated data from server sides (control centers)

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 –Global Positioning System (GPS) integration. Mobile GIS ( 行動式 GIS)

Mobile GIS Architecture

Global Positioning Systems

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

A Scalable GIS Education Program High Schools Community Colleges Universities (four years undergraduate and graduate study – M.A., M.S. and Ph.D. programs) (Seamless GIS Education Integration) Career Ladder for different levels of GIS professionals

Problems Different school levels have different resources and GIS lab setting. (High school: no GIS software/hardware, community college: small GIS labs, few instructors, etc.) Lack of entry-level GIS courses for curriculum articulation (GIS courses in Community colleges (techniques-oriented) are quite different from Universities (theories and research-oriented). Need a Web portal for sharing research findings and publications to the GIS education community (K-12, community colleges, and Universities). San Diego State University Solution: Web-based GIS

NSF- ATE ( Advanced Technological Education) Program) 2004 Award – 3 years Overview: Provide on-line, Web-based GIS learning modules for high school students and teachers. Provide grounding in fundamental GIS theory and concepts for community college students. Create GIS curriculum articulation between community colleges and universities. Help students assess their interest in and aptitude for GIS-related careers, Form an on-line community and portal for GIS- education research and related projects.

Web-based GIS Learning Modules for High Schools Provide Web-based GIS exercises for existing High school courses in Geography, Earth Science, Biology, or Mathematics. Rather than create a brand-new courses for high school students. (Difficult to implement a new course in current high school schedules) Teach ________ with GIS (First Step) Teach ________ about GIS (in the future) San Diego State University

Web-based GIS Advantages Web-based GIS Advantages for high school teachers and students Avoid the complicated (and often expensive) software installation in traditional GIS. Students can utilize a Web browser to access maps and GIS from anywhere (schools, homes, or libraries). Combine with Multimedia (sounds, animation, and 3D) in an integrated Web environment.
