Hurricanes, Beer, and Money
In this exercise we'll make 3 maps:
Hurricane Map
- Download the csv file containing information about Hurricane Katrina. Open the file and view the data.
- Upload the data to GeoCommons.
- Use the latitude and longitude columns for geolocating the data.
- Once you provide metadata and set permissions, make a map from the data.
- You'll notice there's a new option on the left menu window of the map called 'Animate'. GeoCommons recognizes a column that holds a time/datestamp and can use that field to create a time animation.
- Select the timestamp field for the animation, and experiment with the animation functionality.
- See if you can make the size of the circle correspond to the wind speed (wd_sp). Pretty cool!
- Save your map.
Beer, Wine, Obesity
- Download the csv file containing information about wine and beer consumption and obesity per state. Open the file and view the data.
- Upload the data to GeoCommons.
- GeoCommons is pretty smart. It can use the name of the state to join the data to a state boundary file. Choose US Boundaries-->US States. Select the columns on which to base the match.
- Use what you know about GeoCommons to create a choropleth map which symbolizes beer or wine consumption (or both).
- Try different classification schemes as well. Which scheme is your favorite? Why?
- Save your map.
Median Income
- Download the csv file containing information about median income for each county in South Carolina. Open the file and view the data.
- Upload the data to GeoCommons.
- This is pretty tricky, but see if you can join a column in the csv file to county boundaries based on a common attribute. Use trial and error and see if you can get 46 matching attributes.
- Once you do, create a choropleth map which symbolizes median income (from the 2010 American Community Survey).
- Try different classification schemes as well. Which scheme is your favorite? Why?
- Save your map.
