In this chapter, we learned about the most popular spatial data exchange formats for both vector and raster data. We learned not only their specialities but also how QGIS can create them. We also know now how to export our digital maps both as a regular image and in SVG for post-processing. Finally, we learned how to shrink our data or enhance our map by reducing the layers to only cover the relevant parts.
In the next chapter, we will look into the definition and types of databases and how spatial databases compare to them. We will discuss the possibilities of building our spatial data structure and build our very own database with PostGIS and QGIS. Additionally, we will see how QGIS communicates with PostGIS and how we can build basic PostGIS queries.
