Overview

• Define shapefiles and import spatial data using the sf package
• Draw maps using ggplot2 and geom_sf()
• Change coordinate systems
• Generate appropriate color palettes to visualize additional dimensions of data

Before class

• Read Drawing vector maps with ggplot2 and sf

Class materials

• Selecting optimal color palettes

• Practice drawing vector maps

• Mapping data in The Truthful Art by Alberto Cairo - excellent chapter on designing data maps with lots of examples. Though really the entire book is useful if you do a lot of work with data visualizations of any type. UChicago authentication required.

What you need to do after class
