  • You will now have a grid of points that runs to the extent of the site boundary.

  • Go back to the Processing Toolbox and search for ‘Clip’. Open this tool and select ‘Grid’ as the input layer and ‘site_boundary’ as the output, this will cut out a layer of points that fall only inside the site_boundary.
