Sharing Data, Information, and Knowledge

NSF project: Adopting Web-based GIS for the Development of a Scalable GIS Education Program (National Science Foundation: $770,000, 3 years

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

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

San Diego Wildfire 2003 C ombining census data and remote sensing images. (Update daily

Web-based GIS Advantages Web-based GIS Advantages for 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.

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 ). Salary: $47, $73, annually. GIS Analyst II, Clark County Department of Aviation, Las Vegas, Nevada, US # Salary: $60, to $ 80, per year. US-FL-Orlando-GIS Analyst, Hudson Engineering, Operations, and Aerospace.

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. Mobile GIS

Mobile GIS Architecture

Global Positioning Systems

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) g, and n (up to 200Mbps) -- MIMO (multiple input multiple output). Short distance: 300 feet. WiMAX (available in late 2006) d, e (Wireless Metropolitan Area Network (WMAN). 30 – 75 Mbps, 4 – 6 miles

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

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

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

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. San Diego State University Future: Web services? Semantic Webs? Grid computing?
