Week 7 - Choropleth Mapping

GIS 3015

 

 

In the above choropleth map I utilized Natural Breaks classification in order to show the percent changes in the U.S. Population Growth from 1990 to 2000.  This project was done initially using ArcGIS and later modified within Adobe Illustrator to move items around and make the map more presentable.

 

 

 

 

In the above choropleth map I utilized Adobe Illustrator to modify the original map to be grayscale.  Then using an excel spreadsheet I calculated the percent change in each Division.  Analyzing the percent change, I chose Equal Interval classification to assign a color (grayscale) scheme to my map.  The intervals were 5.52 (rounded to nearest tenths value in legend), with one outlier.  Displaying this data using this classification method was the most practical.
