Slide1:  Types of knowledge –andgt; idiographic vs. nomothetic What is a model? Simplified structure Essential components Purposive Bridges theory and observation MODEL Slide2:  Characteristics of models: selective structured suggestive approximates reality reapplication (replication) to real world conditions. Slide3:  Types of models: Descriptive versus Normative Descriptive: static (equilibrium) dynamic (historical) classificatory (taxonomic) theoretical, symbolic, conceptual, or mental mathematical: deterministic v. stochastic Slide4:  Overview of geographic models locational relativity geometrical form 0th order: points 1st order: lines, networks 2nd order: areas, states 3rd order: surfaces, terrain. 4th order: space-time Slide5:  Three-Stage Model for the Analysis of Regional Systems (Chorely and Haggett, 1967) Geographical Form Spatial Model Analytical Techniques Heritage of Spatial Model {0,2} 0 1 3 4 0-4 Dimension Stage I.
