[Talk-us] Green Mountain National Forest cleanup

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/talk-us@openstreetmap.org/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
