GIS

Maps are used to represent many things we are familiar with, such as roads, the geography of politics, climate, resources, and economics. Maps of animal migrations, storms, and McDonald’s locations can be used to visualize patterns across space. By displaying data geographically, maps can reveal patterns that might be hard to discern from a table.

To work with raster data, we will be using a few different packages. If you do not have one or more of the packages, you can install them using install.packages(). After installing packages, you can load them using library().

Note: This version of the article contains static images of maps generated with Leaflet. You can view a version with interactive maps here.
