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

Internet GIS -- Key Technologies

• Internet Map Server (ESRIs ArcIMS, AutoDesks
  MapGuide, INTEGRAPHs GeoMedia Web Map,
  SmallWorlds Internet Application Servers, etc.)
• Componet Programming (JAVA, .NET, ASP..
  (cross-platform Java applets and Java Servlets)

Intro Geospatial Technology Movie (5 minutes)

• On-line lecture notes
• Web-based GIS exercises
• On-line Quiz
• Introduction to Cartography, Remote sensing,
  GPS, GIS and spatial analysis.

13
Mobile 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.

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

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
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
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.

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?
