Here's the official USFS map online: the dark green line is the declared outer boundary of the National Forest. When you zoom in, 2 different colors are shown: the slightly darker green areas are the land owned by the Federal Government, while lighter areas are privately owned. This is easier to see if you click on the gears (Tools) and change the base map to "world terrain".
Sometimes the privately owned land is right up against the outer boundary, which makes it difficult to make valid multipolygons if you exclude them. https://www.fs.usda.gov/detailfull/klamath/maps-pubs/?cid=fseprd533703&width=full I advocated for mapping the outer boundary since land ownership is not something we normally map, but other mappers are saying that the land ownership is more verifiable than the declared boundary and more important for actual protection status and access. – Joseph Eisenberg On Tue, Jun 23, 2020 at 8:18 AM Joseph Eisenberg <joseph.eisenb...@gmail.com> wrote: > On the Talk-US mailing list, other mappers from the USA have been > discussing how National Forest boundaries should be mapped. > > There is now generally consensus that these should be tagged > boundary=protected_area + protect_class=6 but there are 2 possible lines to > follow: > > 1) The boundary declared by Congress (the legislature), which includes > large areas of private land and whole towns in many cases > > 2) The actual land owned by the Federal Government of the United States > within that declared boundary. > > The argument in favor of the second is that the privately-owned land > within the boundary has no actual protection against development.
