In QGIS 2.0.1 Dufour, is there a way to connect different layer roads? Say i have 2 kinds of roads on 2 layers. One is main roads, the other is smaller ones. At the moment they go over each other depending on which of the layers is over another. Is there a way to somehow connect them but keep them on separate layers (with separate markings, line styles etc.)?
If you have something like an TYPE on both shapefiles it is easy:
merge both shapefiles to one using vector-data management tools-merge shapefiles to one.
Add the resulting shapefile to the map and use categorized in the layer properties dialog and use the TYPE to determine the symbol.
