I have a polygon layer representing agricultural fields, but it was generated from a sloppy raster layer that failed to represent narrow roads separating fields. I downloaded a vector layer showing all the roads and buffered it to represent road width (creating a polygon layer). I would like to split up the field polygon layer using the road polygon layer so that a field bisected by a road will be split into two separate features.
Basically, I want something like Vector-->Geoprocessing-->Difference, but that generates new features along the cuts made by the difference layer.
Alternatively, if there is a way to split the field polygon layer by the original line road layer (without the buffer), I could figure out a way to represent road width later on. The priority is to split up the field polygon.
