I'm trying to clip a 30 meter buffer polygon built around a highway line feature using a smaller 6 meter buffer that represents the actual width of the road, so that the original 30 meter buffer is actually 6 meters away from the highway line feature it was created from.
This is so I can calculate slope and land cover, etc., on the edge of the road without including the road itself.
Whenever I try this, it just clips the 30 meter buffer down to 6 meters.
Is it possible to clip a buffer off of its source feature in this way?
