Now we'll have a rail_buffer.shp file that has a 0.5 kilometer radius around the railway line:

Intersection

Intersection gives us back the intersection of two vector files. So, if we have point vector data and line vector data, the intersection will give all of the point data that intersects with the line data. We will now use food court locations, saved as food_dhaka.shp, and see whether there are any food courts within a 0.5 radius of the railway line in Dhaka (contained in rail_buffer.shp); we interpret this by seeing all of the points where food_dhaka.shp intersects with rail_buffer.shp. We can do so by performing the following steps:

Load food_dhaka.shp and then load rail_buffer.shp:
