Guidelines

Guidelines

  • Observe …

    • How we model spatial thinking and analysis

    • The tools we use

Education perspective

Spatial thinking combines …

Concepts of space

Tools of representation

Processes of reasoning

To …

Structure problems

Find answers

Express solutions


Gersmehls modes of spatial thinking

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

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


Why think spatially with gis

Why think spatially with GIS?


Advantages

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

Developing as a spatial thinker

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
