Development of a Scalable GIS Education Program
(National Science Foundation 770,000, 3 years

5
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

6
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

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.

Web-based GIS Learning Modules for High Schools

• Two versions
• Desktop version ESRI ArcExplorer Java Edition
  for Education (AEJEE) Stand-alone without
  network.
• Web version ESRI ArcIMS 9.0 with JavaScript
  customization.
• Two initial learning modules
• Earthquake Chasers Mapping Earthquake Magnitude

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)

13
GEOG 104(http//map.sdsu.edu/geog104)
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.

14
GEOG 104 (at San Diego State Unversity)Geographic
Information Science and Spatial Reasoning

• Fundamental core course in the new B.S Degree in
  Geography Department with Emphasis in Geographic
  Information Science. (Major code 22061).
• Can be used for the Geographic Information
  Science Certificate program (as parts of 27
  required units).
• Promising Career Pathways in GIS
• The U.S. Department of Labor and the U.S.
  Department of Education Career Voyages Web site
  identify the geospatial industry as one of the
  key emerging and evolving industries, along with
  nanotechnology and biotechnology.
• Current Job Listing Examples (searched via Web on
  April-22-2005).
• Salary 47,164.00-73,103.68 annually. GIS

  Operations, and Aerospace.

15
Mobile 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
Mobile GIS Architecture

Global Positioning Systems
18
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

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?
