Selecting optimum sites
Optimum site selection is a pretty common problem, for example, when planning shop or warehouse locations or when looking for a new apartment. In this recipe, you will learn how to perform optimum site selection manually using tools from the Processing Toolbox option, but you will also see how to automate this workflow by creating a Processing model.
In the optimum site selection in this recipe, we will combine different vector analysis tools to find potential locations in Wake County that match the following criteria:
Locations are near a big lake (up to 500 m)
Locations are close to an elementary school (up to 500 m)
Locations are within a reasonable distance (up to 2 km) from a high school
Locations are at least 1 km from a main road
Getting ready
To follow this exercise, load the following datasets, lakes.shp, schools_wake.shp, and roadsmajor.shp.
As all datasets in our test data already use the same CRS, we can get right to the analysis. If you are using different data...
