This was not my original though, but I have found it useful (and mentioned in a sprinkling of places) to think of ZIP codes as a sort of routing algorithm meant to facilitate the efficient movement of mail through the USPS infrastructure. Their history is quite interesting and supports this interpretation, especially with automation and the extensions to 9- and 11-digit codes. > Now I have to wonder if ZCTAs are still around and if they are mapped.

Considering how OSM wants to (and to some decent extent, does) denote census areas as quite distinct from the "OSM-usual" key:value pairs for conurbations, and ZCTAs blend ZIP codes and census boundaries, you'd muddy a lot of water by using ZCTAs, especially as you use OSM data. I, too, (like Clifford) wish you good luck and hope you have fruitful results you might share with us here at the completion of your project.

Re: [Talk-us] National Forest boundaries
A refinement, perhaps Bradley and others agree with me, perhaps not. A USFS NF is a "virtual" multipolygon (not one in OSM, we can get to that later) of three kinds of things: 1) An "outer" (but not the biggest one) which is "the enclosing land which USFS manages, except for inholdings, below," 2) Zero to many "inner" polygons, representing inholdings (and with the usual "hole" semantic of exclusion from 1), above and 3) An even LARGER and ENCLOSING of 1) "outer" which Congress declares is the geographic extent to which USFS may or might "have influence to someday manage." If we ignore 3) as "not real, but rather aspirational or in the future rather than the present, and certainly not on-the-ground" then an OSM multipolygon consists of simply 1) plus 2). Yes?

I think I still need to do some imagination exercises here, and maybe see some examples (in a JOSM buffer, in the real world...) and it will fully crystallize in my mind.

We were doing great there, then I think my (admonishment? might be too strong) way of expressing "owned and operated by the USFS" is technically, accurately stated as "owned by the People, managed / operated specifically by the USFS." If you can agree with me there, I think we can get even closer. If not, that seems like a central core of the snarl in at least my understanding. There are three states we seem to be trying to capture here: 1) land Congress declares is "managed and protected" by USFS, which OSM represents with an enclosing "outer." 2) Excluded from 1) are inholdings, which have role "inner" in the multipolygon. 3) Land Bradley called "owned and operated by USFS" (but which I say is owned by the People and operated by the USFS). See, 1) and 3) seem like the same thing to me. Why would Congress say what Bradley mentions first (at the top of this post) is "managed and protected by USFS" (minus inholdings) and yet there is something "owned by USFS" (when the government owns land, the People own the land; the government agency is operator FOR the People) which I seem to confuse with 3). Am I doing that? Is Bradley? Is Congress? Is it about ownership and operator status being confused in my mind? I'm not stupid, I'm getting closer and I'm grateful for what I hope isn't confused blather.

NF congressionally designated boundary, minus private inholdings (more specifically, non-USFS-owned land), gives you the boundary of land that is actually managed and protected by the USFS. This boundary should be tagged with 'protect_class=6'. USFS owned land is always a subset of this congressional boundary (I suspect it is, in all cases in the US, a proper subset). Subtracting these private inholdings is generally going to change the shape of the 'outer' way such that it no longer is the same as the "designated" boundary. > My slight disagreement with Bradley is as above: I don't think we should put > a "naked" (missing admin_level) boundary=administrative tag on these, it > simply feels wrong to do that. (I READ the point that these are > "Congressionally designated" and that SEEMS administrative...but, hm...). I wasn't clear in what I meant by suggesting 'boundary=administrative' tagging here - I don't think we should tag "declared" boundaries 'boundary=administrative' with no 'admin_level'. This is simply the closest widely-used tag that comes close to representing what this "declared" boundary actually means. This is also why I suggest we think about not including it at all in OSM; should we also start adding boundaries for interstate USFS administrative regions (an 'admin_level', for lack of a better term, more general than a NF boundary), as well as ranger districts within each national forest? The real, on-the-ground objects of importance here are the plots of land that are actually owned and operated by the USFS, not an administrative boundary that declares where each national forest *may* legally be authorized to own and manage land, and that is not surveyable on the ground. ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us

Re: [Talk-us] relations on which thematic data can be connected? eg internet availabilty byt zipcode
Ray, As you learned from Spencer Alves, postal codes are not areas. As far as I know there are no zip code areas in OSM. I would recommend using QGIS and Postgis to construct your queries using OSM and TIGER zip code boundaries. Are you looking for any broadband connectivity, just cellular, DSL, fiber, satellite, or a combination of all of them? My experience is that cellular maps often overstate their reach. Satellite internet service isn't really that great because of the lag time involved. (Upcoming low earth orbit communications satellites promise break thoughts ) Your project is interesting. I hope to read about your conclusions. BTW - I do have friends that only get internet service via their cell phones. Another even used to live off the grid on purpose. When we went looking for a place in rural Washington, we definitely had to exclude places that either didn't have internet service or the cell service was non-existent.

Re: [Talk-us] National Forest boundaries
I (momentarily?) recede from my "watching mode" in this thread to offer my agreement with Mike and to reiterate a slight disagreement with Bradley (or maybe to ask Bradley and especially the wider list here for clarification), as while it seems we get closer to a "more definitive" way to tag NF boundaries, this discussion doesn't seem close to having yielded a complete agreement (yet). Nor even full understanding, at least on my part. My agreement with Mike is noticing that (in California only), CPAD data for NFs are excellent quality; I believe OSM users in California should feel comfortable using them for NFs, as when I look at the "SuperUnit" version of CPAD's release of these (there are also "Unit" and "Holdings," a sort of "parcel-level") NFs invariably have a big, SINGLE outer polygon (and up to hundreds of inners). I wrote wiki on how CPAD data might be best utilized in OSM, see https://wiki.osm.org/wiki/California/Using_CPAD_data . However, I'm not exactly sure how the outer polygons found in NFs differ from either the "Congressional" boundary or the one Bradley says he would tag "boundary=administrative" (and I don't think we should tag it that, especially while excluding a specific value for admin_level), but I'm willing to listen to more discussion about what this "different from Congressional" boundary is and how the two differ. Apologies if that isn't clear, I'm doing my best, but I remain unclear on some concepts here. My slight disagreement with Bradley is as above: I don't think we should put a "naked" (missing admin_level) boundary=administrative tag on these, it simply feels wrong to do that. (I READ the point that these are "Congressionally designated" and that SEEMS administrative...but, hm...). One major problem I have is that we're multiplying polygons (by two) here for a SINGLE national forest. Isn't there a way we can keep all these data in a single relation? Yes, inner can remain as the right role for inholdings, maybe outer is better placed on either "Congressional" or "the other one that is more on-the-ground", maybe we coin a third role ("congressional"?) for that one, allowing us to keep the "bigger, enclosing" polygons in a single multipolygon relation, which I think is an "OSM-sane" thing to do. Summarizing, CPAD data for California: very good. Maybe even excellent, though I think some examination of the differences of NFs between the SuperUnit, Unit and Holdings flavors of CPAD data is a very good idea that somebody (a Californian OSM multipolygon and shapefile jockey who knows something about national forest structure) should take some time to examine. Differences between "the two" kinds of "more outer" multipolygon boundaries of NFs? Murky, well, remaining somewhat murky in my mind, at least how these should best logically be expressed by OSM relations. The discussion is good, I simply reiterate my "I still don't quite understand all of this very well" here and now. Brian seems to agree with me and I don't think I'm alone. Let's keep the momentum rolling until more / most of this achieve that "a-ha" moment as to how OSM should best express NFs with multipolygons.

Re: [Talk-us] Is summit register something that is often found in USA mountains?
Another feature that is often found at summits around here is a roughly constructed shelter, such as: https://images.app.goo.gl/KogTgXChrGx93Ab96 These have been made over the years by various hikers stacking rocks in a semicircle. One can sit down inside them and obtain some shelter from the wind. Some summits have multiple such shelters.

Is summit register something that is often found in USA mountains? ("A summit book or summit register is a record of visitors to the summit of a mountain. It is usually enclosed in a weatherproof, animalproof metal canister.") I am asking as I plan to implement summit register part of https://github.com/westnordost/StreetComplete/issues/561 and I wonder whatever it makes sense to ask this question in USA. So far this kind of object is not mapped at all in USA ( https://taginfo.openstreetmap.org/keys/summit%3Aregister#map ) but https://en.wikipedia.org/wiki/Summit_register claims "The Sierra Club places official registers on many mountains throughout California and the United States."
