Geographic Information Science & Technology Body of Knowledge (GIS&T BoK) • Developed by University Consortium for Geographic Information Science ( UCGIS ) ~ 2000 – 2006 – 10 knowledge areas, 73 units, 329 topics, and 1,660 learning objectives • Influence on GIS&T education globally – U.S., Europe, Latin America, China • “GIS&T BoK2: Foundational Research” – NSF funded for Fall 2010 – Spring 2013 – existing BoK1: top-down construction (experts only) – future BoK2: bottom-up construction (knowledge corpus, community) – components: • BoKOnto – Hunter College • BoKVPE – New Mexico State U. • BoKVis – SDSU • BoKWiki – BYU

The Fabric of the GIS&T Knowledge Domain • GIS&T Body of Knowledge driven by the GIS&T knowledge corpus • BoK : a reference system for the knowledge space we inhabit GIS&T BoK Our Degree My Course GTCM Level 4 Your Job Her Ability Other Domain BoKs

BoKVis: Visualizing the GIS&T BoK • http://geography.sdsu.edu/Research/Projects/BoKVis/ • Plan: – Base map creation from: 1. Current BoK hierarchy 2. Current BoK content 3. GIS&T knowledge corpus – Provide sockets for overlays of: • Text queries • Personal Competencies, CVs • Courses, curricula, institutions  semantic Web based representations

From Measurement to Visualization (via Standards) 1. Measure  size and shape 2. Standardize  reference system 3. Reduce Dimensionality  domain-ignorant 4. Reproject  domain-appropriate 5. Overlay  look for patterns
