Advanced vector and raster analysis with processing

In the following sections, we will cover more advanced processing tools and see how we can use the modeler to automate our tasks.

Finding nearest neighbors

Finding nearest neighbors – for example, the airport nearest to a populated place – is a common task in geoprocessing.

To do this, load the popp.shp into QGIS as well as the airports.shp, if this is not already loaded. Then search for the Distance to Nearest Hub tool (Line to Hub) in the toolbox.
