You might try something like:
How about buffering the country polygon by your tolerance and then get
the results of the buffered country and the river.
Thanks so much, that got me pointed in the right direction. What I
settled on doing is:
intersection(
buffer(exteriorring(geometryn(n.geom,1)),0.02),
r.geom
)
So I turn the county polygon into an exteriorRing and then buffer it out a
bit. Then see what portions of the river intersect that buffered polygon.
thanks!
