Chapter 6 Maps

Learning Objectives: - Plot simple maps using geom_polygon() - Using simple features sf to plot GIS data geom_sf() - Work with map projections and underlying sf data structure - Draw maps using Raster data

Plotting geospacial data is a common visualization task. The process may require spcialized tools. You can decompse the problem into two paths: - Using one data source to draw a map (if you have GIS data) - Adding metadata from another information source to the map (more common with relation to geographic areas)

NOTE: X = Longitude, Y=Latitude. When pronounced “Lat/Lon” it is actually measured as Y/X. Not confusing….just keeping with vocabulary and measurements!
