  3. In Terms of Geography “People manipulate objects (but cultivate fields).” Helen Couclelis 1992

  4. 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

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

  6. “GIS&T match.com” GIS&T BoK Candidate 3 Candidate 2 Candidate 1 GISP Job Posting Other Domain BoKs

  7. Semantic Wiki VPE BoKVis BoKScorecard Text Mining Interface Course Page Job Posting Article External Applications Web Service BoKOnto • Taxonomy • Instances • Inferences • Mappings BoKOnto Server Layer Web Interface

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

  9. Identity Socket Similarity Socket

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

  11. From Measurement to Visualization(via Standards) • Measure  size and shape 2. Standardize • reference system 3. Reduce Dimensionality  domain-ignorant 4. Reproject  domain-appropriate 5. Overlay  look for patterns It’s about Space! Standardization, Conceptualization Abstraction It’s about Things In Space!
