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

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
