  1. July 26, 2012 Thinking Spatially with GIS Dr. Joseph Kerski Laura Bowden

  2. Agenda • Session goals and guidelines • About spatial thinking • Demos / examples • Q & A • Resources

  3. Audience poll

  4. Workshop goals • Identify key components of spatial thinking • Understand spatial thinking process • Help you apply spatial thinking to your work

  5. Guidelines • Observe … • How we model spatial thinking and analysis • The tools we use • Relate to … • YOUR OWN data and decisions

  6. What is spatial thinking?

  7. Demo: Your built-in locator

  8. NRC Report: Learning To Think Spatially Education perspective Spatial thinking combines … Concepts of space Tools of representation Processes of reasoning To … Structure problems Find answers Express solutions

  9. Gersmehls: Modes of Spatial Thinking Brain science perspective Location conditions, connections Aspects of spatial thinking comparison, influence, region, hierarchy, transition, analog, pattern, association Spatio-temporal thinking change, movement, diffusion Exceptions

  10. Dr. Berry: An analytical framework for GIS modeling Geotechnology approach Geotechnology(GPS, RS, GIS) GIS (maps, databases, map analysis) Map Analysis (spatial relationships and patterns) Spatial analysis (geographic context) Reclassify, overlay, proximity, neighbors Spatial statistics (numeric context) Surface modeling, spatial data mining

  11. Why think spatially with GIS?

  12. Advantages • Uncover more efficient ways to solve problems • Uncover other problems to grapple with • Methods can serve as an example to others • May lead to use of new tools, expanding your GIS skills

  13. Effective spatial thinkers need …

  14. Earth quiz Scale Perspective Physical and cultural processes Imagery vs. maps

  15. Spatial pattern quiz Reasoning process Disciplinary knowledge Classification Symbology

  16. Tornadoes & earthquakes Temporal and spatial data Representation Scale dependency Density vs. counts Data source and quality

  17. Boundaries Lines vs. zones Uncertainty Mapping standards Fitness for use Truth in labeling Metadata

  18. Business locations Patterns and relationships Regional vs. national patterns Community Analyst ArcGIS Online Site selection analysis

  19. Population centers Map projections and measurement Change over time Spatial statistics

  20. Questions?

  21. Developing as a spatial thinker • Develop a habit of spatial thinking • Use spatial data to construct, articulate, and defend a line of reasoning or point of view • Solve problems and answer questions • Develop your skills • Deepen knowledge of spatial concepts • Expand knowledge of GIS analysis tools • Be spatially critical • Evaluate quality of spatial data and validity of spatial arguments • Expand content knowledge in your domain
