Introduction to Spatial and Temporal Analysis in Health
Summary
Begin the Slide Show
- History of spatial analysis: some examples
- from other fields or problems (travel, commerce, development
planning, etc.)
- plant and animal ecology; agriculture
- medical geography
- Examples of health-related problems
- characterizing location of health services
- describing the path of an epidemic
- How and why does space matter in epidemiology?
- Depends on question: often assumed/implied in analysis (person,
place, time)
- ignored if looking at entire region
- certain variables may serve as proxy for space
- heuristic value of seeing where and how changes
- analytic value in advancing understanding of mechanism
- gaining insight into process from underlying pattern
- Characteristics of spatial data
- nature of 2-d space, projection, etc.
- description of space: point, line, polygon
- comparisons with other data
- experimental vs. observational
- level of uncertainty: location, attributes
- nature of sample: events, spatial unit
- lack of independence
- Different kinds of spatial patterns and measurements
- Simple methods that evaluate pattern
- mean-variance for point pattern
- Nearest neighbor measures
- Some new technologies relevant to spatial analysis
