In the previous chapter, we learned how spatial RDBMSs work on the example of PostGIS. We went through the typical data types, tables, views, functions, and other objects, while also discussing how we can construct a great spatial database, which can effectively enhance our work.

In this chapter, we will cover the following topics:
- Vector analysis
- Building models in QGIS
- Digital elevation models (DEM)
