In this chapter, you learned the basics of using data in a GIS. QGIS 3.4 supports all the formats in OGR and GDAL. The default format for QGIS 3.4 is the GeoPackage. We also looked at creating and editing Vector data, as well as attribute tables and geometries. Furthermore, we joined data and used snapping tools to preserve topology. Don't ignore Raster data though; we will use it many times throughout this book. In this chapter, we briefly reviewed its creation and hinted at the powerful GDAL tools built into QGIS. Finally, we looked at spatial databases in QGIS 3.4 and connected to them in DB Manager.
In the next chapter, we will look at styling and visualizing this data.
