Why Internet MappingWhy 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.

A A ScalableScalable GIS Education Program 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
ProblemsProblems
• 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 AdvantagesWeb-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.

ChallengesChallenges
• 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.
