Schuurman: GIS: A Short Introduction
Ch. 4: Bringing it All Together: GIS Analysis
GIS is often used to store data; analysis greatly extends the functionality of GIS by allowing us to learn more about the stored data
Cadastral systems: property and attribute information (Delaware DALIS project)
- storing data vs analysis (how many residential properties within 1000’ of river)
Examples of analysis:
- measurement & distance calculation (perimeters, areas, line lengths)
- point in polygon queries: does a point lie in an area?
- shape analysis: shape of a line to assess difficulty of driving on a road
- edginess analysis: deer habitat (prefer ediginess, forest grass boundary)
- slope calculation
Overlay Analysis, Set Theory, Map Algebra
- query: a question (show all owl locations > 500’ from road)
- buffer: an area around a pt, line, area (show residences within 500’ of liquor lic. Appl.)
- overlay analysis (find all soils of a particular type within a floodzone)
- difficulty of polygon overlay: extensive calculation
- set theory & map algebra: mathematical basis of GIS analysis
Spatial Analysis in the Field: Environmental Modeling
- ex) modeling industrial pollution
- predict the impact of a new industrial development in a particular location; help
- in decision-making
- air emission, noise, risk
- link environmental modeling to spatial data
Building Intuitive Models: Multi-Criteria Evaluation
- location decision analysis
- find the best location for a new industrial development, given multiple criteria (away
- from people because of pollution; near necessary transportation corridors, labor).
- ex) locating a dump
- factors and criteria: p. 110
- resulting map: worse and better locations: p. 111
The Power of the Eye: Visualization and the New Cartography
- ex) TB example
From Data to Analysis: A Case Study of Population Health
- ex) population health: relating housing to health
- ecological fallacy: aggregation or scaling introduces bias (p. 120)
MCE and Analysis
- example of health vs density of population
Calculation and the Rationalities of GIS
- critical perspectives
Ch. 5: GIS Training and Research
