In the last chapter, we discussed vector analysis, and how we can perform it effectively. After explaining the basics in QGIS, we harnessed the power of PostGIS and carried out our analysis with unpaired speed. We also queried rasters, and executed a basic terrain analysis operation getting aspect values in the locations of our randomly generated houses as a result.
In this chapter, we will move on and discuss raster analysis in detail. We will learn how to use the most essential raster tools, and what kind of typical operations we can do with rasters. To spice up this chapter, first we create a scenario where we are decision makers. We search for the ideal site of our business, and we've already evaluated the criteria for the optimal site.
