Hi Brad, thanks for proposing this import and posting it here. I would strongly prefer that we not import boundaries like this into OSM. Boundaries of all sorts are almost impossible to verify with OSM's "on the ground" rule, but BLM boundaries in particular are such an edge case (they have no other analog in the world, really) and almost never have apparent markings on the ground to check. Since these boundaries aren't visible, this data can never be improved by an OpenStreetMap contributor. The boundaries are defined by the government, and any sort of change to them would make them diverge from the official source.
But having said that, I'm curious why you wanted to import this data? Did you want to have it show up on the osm.org map? Are you trying to build a custom map? Or are you excited to participate and improve OSM? If it's the latter, there's lots of other data that is a better fit to import into OSM: address points and building footprints come to mind, for example. -Ian On Sat, Jan 5, 2019 at 9:03 PM brad <bradha...@fastmail.com> wrote: > I'd like to import BLM (US Bureau of Land Management) boundaries into > OSM.
