GIS & A Spatial Question
• London Cholera Epidemic of 1854
Image from http://www.ph.ucla.edu/epi/snow/watermap1856/watermap_1856intro.html
Map on following page from http://www.crissycorkboard.org/gis_class/london.htm
A Spatial Question?
Each dot represents one death from cholera.
500 people died in the epidemic, caused by a contaminated well.
So what is GIS
really…
Image from Google Earth
GIS is a representation of the
„real‟ world
• Layers with attributes
• Vector Data
– Points
– Lines
– Polygons
• Raster Data
– Images
– Grids Image from ESRI
Three „views‟ of GIS
• Database
• Map
• Model
The kinds of questions you can
answer with GIS
• Measurement: How far is it? How large is it?
• Location: Where is it?
• Condition: What location fits specific
conditions?
• Proximity: What is it near? What is adjacent to
it?
• Trends: What has changed since....?
• Patterns: Which spatial patterns exist?
• Routing: Which is the best way?
• Modeling: What if...?
Questions obtained from http://www.ruralgis.org/publications/documents/citizen.pdf
The GIS Process
• Ask a question
• Obtain necessary data
• Determine best method of analysis
– Temporal
– Spatial
– Attribute
• Analyze
• Present results
Chance is not enough!
“Planning is the idea that…changes are not
best left to chance; land, cities, natural
resources, economy, and infrastructure all
deserve directed attention and guidance.”
(University of Michigan Taubman College of Architecture & Urban Planning)

TOP sites were
located in them?
A few miscellaneous words

& assets
• Web services
– Letting people shape their future online
