Week 3: Thinking Spatially/GIS Flashcards
Spatial cognition
How we think about the world around us
Associated with cognitive mapping: process by which we acquire, code, store, recall and decode information about the relative locations and attributes of phenomena in environment
Spatial reasoning
How we come to conclusions about the relationships among phenomena in space
Spatial knowledge discovery
Synthesizing information about spatial relationships in support of decision making
Questions answered by cognitive mapping
Where are things of value?
How to get to where they are from where we are?
Signature of a map code
The way in which spatial information is encoded and decoded
Dependent on rotation of a point of view to a vertical perspective, change and selection of scale, abstraction to a set of symbols
GIS
Geographic information systems
Technology, information handling strategy
A system for capturing, storing, checking, integrating, manipulating, analyzing and displaying data which are spatially referenced to the Earth. This is normally considered to involve a spatially referenced computer database and appropriate applications software
GIS has developed from
Digital cartography and CAD
Database management systems
Topography
Connectedness
Adjacency
Containment
Directional
Common outputs from epidemiological analysis
Tabular output
Cartographic output
Air pollution exposure assessment
How do we estimate exposure to air pollution for people who may have respiratory or cardiovascular risk factors who live in locations for where we do not have measured air pollution data
Reducing misclassification of exposure (or access)
How can we incorporate GPS data to improve models of exposure to health harming or promoting factors in the environment
Location-allocation modeling
Frequently used for solving location problems and involves the locating of facilities by selecting a set of sites from a larger set of candidate sites
