Hey I am a first time user of GIS and I am working for a transportation map of North Carolina for a project at my work. So what I have been doing is first placing the Tiger County Boundary by using the add vector layer tool and selecting the directory setting and then select tiger. I then do the same thing for a layer that contains all of the roads. They do not line up and the road layer is significantly larger than the county boundaries. I tried to mess with the CRS, but it did not seem to change anything. I am just taking a guess, but I am assuming that it is a scaling issue? Anyway please help
If you turn on On the Fly Projection in the Options, that will make sure layers with different CRS's will line up correctly, assuming they have the correct CRS assigned.
