Week 6: Proportional Symbol and Bivariate Choropleth Mapping

 
Proportional symbols are helpful for depicting changing values. The above map depicts job activity and one can clearly see which states has the most job growth. Use of differing colors can help to distinguish which values are increasing and which are decreasing. Additionally, only one legend is needed for each symbol.

Bivariate can help to visualize patterns and outliers. by using colors one can see how two variables influence one another, in the above example physical inactivity and obesity. I prepared this data by classifying the percentages into classes. For example, low obesity counties would be class 1, and low physical inactivity would A. I then combined the classes into another field to create unique values for the bivariate and then developed colors that would mesh well together, like red and blue to create purple.

Week 5: Analytics

 

For this week I created an infographic to showcase the trend between counties with higher rural populations and counties with high obesity.

Week 4: Working with Color

 

The map I created this week highlights the population change in Georgia from 2010 to 2014. I chose to create 5 classifications and used quantiles as my classification method. I chose 5 classifications because it helped to distinguish areas with some growth and areas with a large amount of growth. I believe this created a more even looking distribution, and also was able to highlight the regions of Georgia that are growing the most. In addition, There are set at 4 break points: -3, -1, 1, and 3. These breakpoints define the quantiles.

Week 3: Terrain Visualization

 

This week I created an ArcScene that showcases the elevation of Death Valley, CA. I added a dvtin layer to symbolize the change in elevation. I then snipped a screenshot above of an area that best captures the change in elevation.
