I have two shapefiles that I want to use to see all the roads in one particular province of The Netherlands.

So I have one layer with all the roads in The Netherlands and one layer with the boundaries of every province.

How can I 'select' or 'show' the roads in this one particular province? The attributes of the roads file doesn't contain data saying in wich province it is.

I am a beginner in using QGIS 2.0.1.


You can use an intersection of the features. You can find it here: Vector > Geoprocessing Tools > Intersect...

enter image description here

As the input layer you use the roads. As intersect layer you use the provinces of the netherlands. Either you can make a filter for the province you need or you select the province and check the Use only selected features box. Then you can process a new shapefile with only the streets of the area.

If you want that the roads are clipped at the province boundaries, you can use the clip function of qgis: Vector > Geoprocessing Tools > Clip....

  • I think this is what I was looking for, but the resulting shapefile appears to be empty. I tried this with leaving the checkboxes clear: no result. Then I selected one province, checkboxed 'Use only selected features'. Processing took 3 minutes and it created the new layer but it's empty. – Sander Feb 24 '15 at 14:40
  • Are the layer in the same coordinate reference system? The systems are in left click in the layers menue > Properties > General > Coordinate Reference System If you open the generated file in another project it is still empty? – Martin Feb 24 '15 at 14:54
  • They aren't. But when I change the CRS in that menu, the shapefile/polygons disappear. – Sander Feb 25 '15 at 8:23
  • Try to save the both files in the same crs. Here is the QGIS manual on how to do this: docs.qgis.org/2.2/de/docs/training_manual/vector_analysis/… This should transform the coordinates to the other crs and the position should be the same. – Martin Feb 25 '15 at 8:39
