Hello all, I'm planning to do some cleanup of the Green Mountain National Forest in Vermont and figured it might be useful to provide the opportunity for feedback before embarking on this project.
The Green Mountain National forest is currently mapped as two large outer-area relations that include large swaths of private land and many ways and relations that mark independent parcel boundaries -- the latter having a multitude of tag schemes. Outer area boundaries: - northern section: https://www.openstreetmap.org/relation/2030450 - southern section: https://www.openstreetmap.org/relation/1610349 Many parcel boundaries (examples): - https://www.openstreetmap.org/relation/6850907#map=13/44.0444/-73.0668 - https://www.openstreetmap.org/relation/6631735#map=12/44.0070/-72.9569 - https://www.openstreetmap.org/way/116060714#map=12/44.0123/-72.9418 - .... There is very little consistency in the tagging of the parcel boundaries -- many are tagged as boundary=national_park, others are tagged as boundary=protected_area. As well, many [most?] are tagged with landuse=forest even if they are sensitive areas (protected watersheds), wilderness areas (no logging allowed ever), designated recreation areas, or otherwise not open to logging. I propose to group all of the parcel boundaries into two super-relations, one for the northern half of the GMNF and one for the souther half of the GMNF. These super-relations would have: - type <https://wiki.openstreetmap.org/wiki/Key:type>=boundary <https://wiki.openstreetmap.org/wiki/Tag:type%3Dboundary> - boundary <https://wiki.openstreetmap.org/wiki/Key:boundary>= protected_area <https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dprotected_area> - protect_class <https://wiki.openstreetmap.org/wiki/Key:protect_class>=6 - protection_title <https://wiki.openstreetmap.org/wiki/Key:protection_title>=National Forest - protected <https://wiki.openstreetmap.org/wiki/Key:protected> =perpetuity - operator <https://wiki.openstreetmap.org/wiki/Key:operator>=United States Forest Service - leisure=nature_reserve (this seemed to be recommended in the "Okanogan-Wenatchee National Forest (landuse=forest and US National forests again) <https://www.mail-archive.com/[email protected]/msg16713.html>" discussion a few months ago) as described on US Forest Service Data wiki page <https://wiki.openstreetmap.org/wiki/US_Forest_Service_Data#National_Forest_Boundaries>. The members of this super-relations would have their own tags either normalized to the same values above the super-relation (maintaining additional parcel-specific details) or would have their duplicative tags removed. In particular, the boundary=national_park tag would be be normalized to boundary=protected_area and the landuse=forest tag would generally be removed. I'm planning to do all of this cleanup manually sometime soon and just wondered if anyone had any further suggestions. I guess an alternative process would be to reimport the parcel boundaries from the latest "Survey Boundaries maintained by the US Forest Service <https://data.fs.usda.gov/geodata/edw/datasets.php>" file, but I'm not sure if that might be more difficult or easier. Thanks for any input! Adam https://www.openstreetmap.org/user/Adam%20Franco
