- QGIS will automatically zoom to the extent of the bus stop features
- Run the buffer process from the menu: TOOLS -> Geoprocessing Tools -> Buffer(s)
- Set the Input vector layer to busstopsall
- Enter Buffer distance of 200. This will be 200 metres.
- Set the Output shapefile by pressing Browse button. Navigate to the data folder and enter the new filename as busstops_200m_buffer.shp. Press Save button to select that filename.
- Press OK button to run the process.
- After running, the system asks Would you like to add the new layer to the TOC? select Yes and the resulting shapefile will be added as a layer in your map view.
- Buffer(s) window remains open. Press Close to close the window.
- Reorder the layers so the resulting buffer polygons layer is on the bottom of the layer stack. Click and drag the busstops_200m_buffer.shp layer to beneath busstopsall.
