  3. 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)

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

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

  16. 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). 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

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

  18. Real-time report submission and data upload (from Pocket PC to Server)

  19. Evaluate Land Cover Change by ADAR Images via Internet Map Server (MTRP BMX site)

  20. 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)

  21. REASoN Project Real Time GIS for Emergency Response(NASA funded REASoN Project, $1.8 million for five years)Http://geoinfo.sdsu.edu/reason

  22. Metadata/Data Portal Metadata is the key to effectively search/query GIS data across the Internet

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

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

  33. 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

  34. San Diego State University 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). Solution: Web-based GIS

  35. 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.

  36. San Diego State University 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)

  37. Web-based GIS Advantagesfor 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.

  38. Internship program:GPS IntegrationTraining

  39. San Diego High Tech High School -- biology course • San Diego Bay Biological Survey • Study • Diversity at Different Sites • Affect of Human Activity • Affect of Tidal Flow • Appreciation • Scientific Field Work/Inquiry-Based Learning Barnacle (Boat Channel Study: HTH Biotech Website) Student Field Work (Boat Channel Study: HTH Biotech Website) Flatworm (Boat Channel Study: HTH Biotech Website) Student Field Work (Boat Channel Study: HTH Biotech Website) File Limpet (Boat Channel Study: HTH Biotech Website)

  40. San Diego State University Challenges • Need to develop evaluation methods for Web-based GIS educations and Modules (How effective?) • Cope with technology changes (Web technology changes every month). How to migrate from old technologies to new tools? • Supports from administrative level. Future:Web services? Semantic Webs? Grid computing?
