Visualizing spatial data I

Overview

• Introduce the major components of a geospatial visualization
• Identify how to draw raster maps using ggmaps and get_map()
• Practice generating raster maps
• Demonstrate geofacet and facet_geo()

Before class

• Read Introduction to geospatial visualization
• Read Drawing raster maps with ggmap

Class materials

• Practice drawing raster 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. Cornell authentication required.

Additional resources

• Learn Spatial Analysis - tutorials and workshops conducted by the Center for Spatial Data Science at the University of Chicago. Lots of materials developed using R.

What you need to do after class

• Obtain an API key and store it securely on your computer. We will be using tidycensus next class, so you will save time if you set this up in advance.
