Nobody's proposing that they just be combined. The wilderness area is still "part of" the National Forest; it will be mapped separately, but will not be cut out of the National Forest boundary. We've done things that way for non-Federal wilderness areas in New York for quite a while now. For example, the Indian Head Wilderness https://www.openstreetmap.org/relation/6365026 is mapped, and is not cut out of the larger Catskill Park https://www.openstreetmap.org/relation/6265477 because the Indian Head Wilderness is a part of the Catskill Park. To map the Catskill Park as being, "the designated area of the Catskill Park. minus the State-designated Wilderness, Wild Forest, and Primitive Areas, the New York City Watershed Recreation Areas, the state campgrounds, the Catskill Visitor Center, the Catskill Center for Conservation and Development, the Nature Conservancy and Open Space Institute reserves, and the Belleayre Ski Center (and I'm probably forgetting a few other more-protected areas)" would be pretty nonsensical. I think data consumers have to be prepared to deal with the fact that national parks and other large reserves will have parts that have a different protection class from the default for the reserve as a whole. This practice is also consistent with IUCN recommendations: see https://portals.iucn.org/library/sites/library/files/documents/PAG-021.pdf pp 36-38. "Can a protected area contain more than one category?" which specifically contemplates that management zones within a larger protected area should acquire their own protection class when they are clearly mapped, recognized in law or by other effective means, have unambiguous management aims that are distinct from those of the larger protected area taken as a whole, and are of significant extent. A wilderness area within a National Forest satisfies all of these conditions. Moreover, the same section of the guidelines specifically warns that a data model must guard against overcounting when using such 'nested' areas for statistical analysis. -- 73 de ke9tv/2, Kevin _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
