Thanks Michael and Liz. I've been thinking about this for a while, and putting off mapping many of the streams/rivers in the Sierra Mountains because of this uncertainty. It seems that there is no general consensus, so I would like to propose what I think is the best trade-off: I think that if

I'd prefer relations. Duplicating the line to offset is borderline micro-mapping; I don't think micro-mapping is practical in a lot of cases right now. On Tue, Aug 10, 2010 at 3:08 PM, Erik G. Burrows wrote: > >> I have several cases where a border polygon (national park, wilderness, > >> etc.)

I have several cases where a border polygon (national park, wilderness, etc.) is defined based on a natural feature, such as a stream/crestline/etc. What is the preferred way to handle this dual-purpose way? Splitting the border way, creating a relation of the border pieces, and adding the natur
