Chapter 4. Spatial Analysis

In this chapter, we will use QGIS to perform many typical geoprocessing and spatial analysis tasks. We will start with raster processing and analysis tasks such as clipping and terrain analysis. We will cover the essentials of converting between raster and vector formats, and then continue with common vector geoprocessing tasks, such as generating heatmaps and calculating area shares within a region. We will also use the Processing modeler to create automated geoprocessing workflows. Finally, we will finish the chapter with examples of how to use the power of spatial databases to analyze spatial data in QGIS.
