Gi science discipline_foloo

  1. 1. OLOO FrancisGeographic Information Science Seminar Msc winter 2012/13
  2. 2.  1. Introduction 2. Development 3. Components 4. Laws of GIScience 5. Impacts of GIScience 6. Conclusion
  3. 3.  Geographic Information Information about phenomena and features in thevicinity of the earth’s surface Geographic Information Science The basic research field that seeks to redefinegeographic concepts in the context of GIS
  4. 4.  Scientific motivation Facilitate (complete) understanding of geographicphenomena and their representation Contribute to conceptualization, methods and toolswith which to approach geographic phenomena Contribute to the infrastructure of science for all theother disciplines dealing in geographic space
  5. 5.  Technological motivation Ensure logical and consistent representation ofgeographic phenomenon in view of advances intechnology Societal motivation Address impact of GI technology in societal issuese.g. democracy, empowerment, privacy
  6. 6.  Alber R, F (1987) Began to advocate for a center to be funded byNational Science Foundation Suggested potential areas of research as▪ Spatial analysis and spatial statistics▪ Spatial relationships and DB structures▪ AI and expert systems▪ Visualization▪ Social, economic and institutional issues
  7. 7.  Goodchild (1992) Introduced the term Geographic Information Science Suggested research areas for possible recognition ofGIScience in NAS Mark DM (2000) Published a comprehensive approach of defining thefield of GIScience
  8. 8.  UCGIS (2002) Dedicated to the development and use ofmethods, technology and data for understandinggeographic processes, relationships and patterns Transformation of geographic data to usefulinformation is central to GIScience Has been active in setting research Agenda forGIScience
  9. 9. The human•How do people conceptualizetheir surrounding?Society•What factors determineadoption and how does GItechnology impact society?Computer•How can we take advantage oftechnology to improvefunctionality?Goodchild (2010)
  10. 10.  Should address scientific questions that arenot yet solved Topic should be generic Topic should be hard and should berecognized as such
  11. 11.  Tobler’s First Law Found an (application) home in GIScience▪ Spatial Autocorrelation▪ Interpolation▪ Resampling▪ Contour mapping
  12. 12.  Principle of spatial heterogeneity Results of any analysis depends on the bounds Fractal principle Geographic phenomena reveals additional information thecloser one looks at it (GE) Principle of uncertainty Geographic world is complex, every representationcontains “uncertainty”

  18. 18.  Institutional frameworks University Consortium of Geographic InformationScience (UCGIS) Association of Geographic Information Laboratoriesin Europe (AGILE) Geo-Information Society of South Africa (GISSA) Association of Geographic Information (AGI) UNIGIS
  19. 19. AGILE Members
  20. 20.  Education curricula (post graduate) There are many study programs in GIScience andrelated disciplines all over the world Closer interaction between the industry andeducation 79 Universities as members of UCGIS (76 from US) UNIGIS study program (9 University members)

  22. 22.  Wide areas of application Disaster management Medicine Climate change Agriculture Energy Refugee management Pollution control etc
  23. 23.  GIScience is developing into a scientificdiscipline Well defined field with its own scientific domain andunique questions Emerging laws/ principles Growing institutional framework Impact in scientific research, education Ability to meet specific and vital needs
