3Why 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,
etc.) Real-time Information Update and
Distribution Gather data from (?????????) client
sides (polices, firefighters), Distribute updated
data from server sides (control centers)

16Web-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)
17Web-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.
18Mobile GIS (???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.
19Mobile GIS Architecture
20Global Positioning Systems
21Wireless 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

37Problems
- 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
38NSF- 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.

41Challenges
- 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?
