Clipping features

In order to clip our layers we need two things--an input layer, and a clip layer. The clip layer contains the cookie-cutter, while the input layer is clipped to the clip layer's shape. As we have a filter on our administrative boundaries layer, we have the perfect clip layer at hand. Any vector layer can act as an input layer, however we should only consider layers sticking out from our study area. For every input layer, we have to iterate the following steps one by one:

1. Select QGIS geoalgorithms | Vector overlay tools | Clip from the Processing Toolbox.
2. Select the current input layer as Input layer.
3. Select the filtered administrative boundaries layer as Clip layer.
4. Type memory: as the output name.
5. After running the algorithm, ...
