Chapter 8. Spatial Analysis in QGIS

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. Now that we can ease our job by using spatial databases, we will move on and learn about spatial analysis. To have a full-blown example on which we can work, let's assume we are very enthusiastic real estate agents. We are happy to go that extra mile to please our customers who have very specific conditions on their dream houses. The price and size of the house does not matter in this case, although its situation must meet certain criteria.

In this chapter, we will cover the following topics:

  • Vector analysis
  • Building models in QGIS
  • Digital elevation models (DEM)
  • Using GRASS from QGIS
