  • We'll be using ArcPro and ArcOnline for today's demo. You'll need to create an ArcGIS Online account here. To download and install ArcPro, go here.

  • ArcOnline is compatiable with Mac and Windows OS; ArcPro is only compatiable with Windows OS

Goal of this workshop

This workshop is meant to serve as an introduction to bivariate choropleth mapping. It's a simple workshop that you should be able to replicate on your own afterwards.




By the end of this workshop you will be able to:

  • Distinguish between univariate and bivariate

  • Use resources from ArcGIS Online public layer sources

  • Knowledge of basic symbology functions

  • Ability to make a bivariate choropleth map and layout

  • Resources and support opportunities



















Considerations

  • Normalize your data (!)

  • Use variables you suspect have a relationship (e.g., rainfall & diabetes vs. obesity & diabetes)

  • Not statistically significant, only looking at highest vs. lowest values of overlaid variables





Data





To be used during demo

  • Join fields "GEOID" from US.shp and "CountyFIPS" from Sheet1$
  • Copy and paste: Obesity and Diabetes Measures 2016 CDC
