To fulfill most of our criteria, simple proximity analysis is enough. However, there are two types of criteria. Some of them state that our results have to exceed a distance, while the rest of them require the results to equal a certain distance. For the sake of simplicity, let's separate those requirements, and solve them one by one. The easiest way to do a proximity analysis with fixed distances is to buffer the features we want to compare our houses with, and use a spatial query to get matching results. We can delimit houses far enough from noise-polluted areas by the following (from now on, saving intermediate results as memory layers won't be emphasized):
- Open the roads and landuse layers.
- Apply a filter on the
