Shapefile I am referring to is 'NUTS_RG_03M_2010' which is together with several other shapefiles available in a ZIP file on the Eurostat web site.
I am importing NUTS_RG_03M_2010.shp as a vector layer.
Actually I am interested in the NUTS 2 or 3 level - not the here displayed national level. Now I print this map in a PDF and when I open it I can see the different layers in short intervals displayed - from very fine grained to the national level. The screen shot shows one intermediate level:
My conclusion is that those levels, layers or whatever it is called are "hidden" somewhere and must be displayable and editable in QGIS. How do I access them?
My ultimate goal is to convert a NUTS 3 level layer to GeoJSON or SVG.
