Create a new QGIS project and save it in the QGIS Training > Essentials folder

Open the nat_parks_england and railway_naptan layers

In the nat_parks_england layer, Select the Lake District national park (check in the Attribute Table if you are not sure which one this is)

Find the Buffer tool by searching in the Search box, and create a 10km buffer round the Lake District National park - be sure to check Selected features only, and create a temporary layer

Use the Select by location process to find out how many railway stations are within the Buffered layer - look at the attribute table for railway stations to get the count

Open the boundaryline.county_region layer from the Postgres training database

Find the Centroids process, and use it to create a new layer of the centroids (the centre point) of each county

Use the Join Attributes by Nearest process to add the details of the nearest railway station to each centroid feature

Look at the attribute table for the Centroids layer to check the result, and add a label showing the name of the nearest station to the

centroids layer

Zoom to the extent of the railway stations layer

Create a 30km hex grid for the extents of the layer, with settings as shown in the screenshot - to get Grid extent, click the three dots to the right of the

field and use Calculate from Layer

Get the number of stations in each hexagon by using Count points in polygon, and check the attribute table for the results

If you have time and want to try some styling, create an appropriate Graduated style for the grid layer, so that areas with higher concentrations of stations are shown darker than those with no or few stations, and add a label showing how many stations there are in each hexagon
