This chapter provided a refresher on the basics of QGIS and a look at some of the new functionality of 3.x. We covered how to install the software on several platforms. We then covered how to load vector, raster, and database data layers. Next, you were shown how to work with coordinate reference systems and style data. We covered the basics of working with tables, including how to perform a table join. The chapter concluded with a refresher on composing maps, how to find, install, and manage plugins, and a primer on QGIS custom variables.
The next chapter will cover styling vectors and raster data. Now that you have had a refresher on the basics of QGIS, it is time to learn how to expand your work to include spatial databases. In Chapter 3, Creating Spatial Databases, you will learn how to create and manage spatial databases within QGIS.
