Part Eight: Final Exercise


Slide2 l.jpg

Final Exercise

A farmer is found with a high fever and developing pustules on his

outer extremities, especially on the souls of his feet and

palms of his hands.

The EOC draws an immediate exposure

area of 500 meters around the farm.


Slide3 l.jpg

In GIS speak, what is this exposure area called?

In epidemiology speak what would this area be called?

Why did the EOC do this?

How would this area be turned into an exposure buffer

on the ground?

What data sets are visible, what other datasets would be useful?

10 minutes


Slide4 l.jpg

Two more exposure areas of

An additional 500 meters have been

drawn


Slide5 l.jpg

Why would these additional buffers be added?

What additional information would the

EOC ask the field team for?

5 minutes


Slide6 l.jpg

All roads entering or within the buffer have been selected


Slide7 l.jpg

What type of GIS data is a roadway?

Where would you get this data layer?

Why would you want to query roads inside the buffer?

5 minutes


Slide8 l.jpg

The Roadway has been buffered to 100 meters


Slide9 l.jpg

Why would you want to buffer the road?

5 minutes


Slide10 l.jpg

All surrounding farms have been added


Slide11 l.jpg

Why would you want to add these farms?

What type of GIS feature are farms?

Name three ways these farms could be added into the GIS

7 minutes


Slide12 l.jpg

The farm size has been visualized to show amounts of an attribute


Slide13 l.jpg

What is an attribute?

What possible attribute could be relevant to be visualized

in this way for this example?

3 minutes


Slide14 l.jpg

Those farms meeting a specific query

have been selected out


Slide15 l.jpg

How do we know which farms have been selected out?

What might the query of the GIS have been?

What would the attribute table look like?

5 minutes


Slide16 l.jpg

Contact information on the farm is displayed


Slide17 l.jpg

What is the easiest way to get this information

about a single farm in the GIS?

If the EOC believes the disease is airborne – what

Other GIS layers would be needed?

If instead of an isolated farm, multiple cases of the disease had

started to develop in a nearby urban area, how could the EOC

have found a possible origin?

10 minutes


Slide18 l.jpg

How would the concept of social

vulnerability mapping be incorporated in the the EOC

decision making process?

What data would be needed to make a choropleth map?

What dangers are involved in using this cartographic display?

How could spatial sampling, and point-in-polygon improve

what the EOC knows about the vulnerability of populations?
