I'm not sure what you mean by the question. Many parks over here have 'inholdings', which are other land in the parks not owned or managed by the park administration. I'm consistent about mapping those, which is why park boundaries are usually multipolygons. The sites that I mentioned in Bear Mountain are mostly administered by the park administration. The inns are operated by a contractor (but the operator is responsible to the park management), the hiking trails are maintained by an NGO, and the research reserve is some sort of cooperative arrangement with NYS Department of Environmental Conservation and a couple of other government agencies, and I don't know the all the details. To a visitor, all but the last are 'part of' the park. (The research reserve has more restricted access, but is still managed in part by the park under the cooperative agreement.) The park's boundaries are exactly (well, to within the limits of the data source, which is not 100% trustworthy, but I verified against highway, railroad and river alignment, and against a couple of other data sources for the boundary with West Point) as shown by the multipolygon https://www.openstreetmap.org/relation/6467468. The rights-of-way for the railroad and the highways, and both of the settlements that I mentioned, are not part of the park, and are cut out of the multipolygon. I didn't need to use inner ways for those, simply because they all connect to the world outside, but we do have protected areas with quite complex topologies indeed: https://www.openstreetmap.org/relation/6365096 is an example and https://www.openstreetmap.org/relation/6362702 is a worse one that took many hours to map. even with the aid of an import. (I *don't* just drop imported data in blindly!) The Fort Montgomery historic site is technically a separate site (Fort Clinton *is* part of Bear Mountain State Park), and is mapped thus - but it, Bear Mountain, and Harriman and Sterling Forest to the west are under common management. Yes, one of the inn buildings encroaches on the Palisades Parkway right-of-way. The agencies that administer those two objects are friendly. The concessionaires rent their stalls. The rest of the historic sites, I've not done the research to see if they're listed. Many of them are off limits - you're supposed to stay on trail in the backcountry in that park (because many of the old industrial sites are still hazardous - they don't want people falling down mine shafts or being injured by abandoned and decaying machinery). Doodletown has interpretive signs at a lot of its ruins, so I wouldn't be surprised to find NRHP listings there, but I haven't yet looked. I'm not sure what I'd do with a site relation here. I'd use it, if for instance, the park had an office occupying part of a building that wasn't in the park, so I'd need a node for that. I've done site relations for urban universities that have outreach programs in off-campus space, but why bother with a site when a multipolygon will do? _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
