This is about https://www.iso.org/obp/ui/#iso:code:3166:IO which will stop to exist „by the end of the year“ https://digitalcourage.social/@mat@friendica.exon.name

We will mark it as "deprecated" and send an `Update` then.
What else to do?

SayWhere Geocoding System: Human-Memorable Geographic Coordinates

This document specifies SayWhere, an open-source system for encoding geographic coordinates (latitude, longitude, and optional altitude) into human-memorable word phrases and decoding them back to coordinates. The system provides deterministic, reversible encoding with two-layer error detection (per-word parity and optional terminal word-phrase checksum) and supports three-dimensional positioning for multi-level structures. SayWhere introduces hierarchical variable- length phrases with true prefix relationships, enabling precision scaling from regional (1 word) to meter-level accuracy (6 words). The system uses the Bitcoin Improvement Proposal 39 (BIP-39) mnemonic wordlist for multilingual support and geohash spatial indexing for efficient location encoding.

I just stumbled upon @socialcg's Geosocial efforts and added a bit of my perspective on public transit checkins https://github.com/swicg/geosocial/issues/20. Would be really cool to have these on the social web :)

Checking into public transit · Issue #20 · swicg/geosocial

Hi! I just stumbled upon this repository while researching event formats viable for federating a platform like träwelling or travelynx. I'm happy to see such recent work on this area and would like...

We're experimenting with federated geosocial features in Bonfire, free from surveillance capitalism.
Check into your local community garden. Add location to mutual aid requests. Find tools nearby.
Imagine your local fablab or community center sharing check-ins, calendars, events, opening hours - all federated. A living hub for what's happening there.

This unlocks new possibilities for local organizing, let's explore together 🔥

Seeking interop testing for geosocial ActivityPub client

Hey, all! I’m seeking some help testing an application I whipped up for the Geosocial task force of the W3C Social Web Community Group. It’s called https://checkin.swf.pub/ , and it’s a barebones checkin service, similar to Swarm, but implemented as a pure Web client. You can watch the application in action.

@Jeremiah #geosocial
working now on a compact representation of all the geo things described in https://github.com/w3c/activitystreams/issues/582#issuecomment-2498916869

It is for a kv store which would play nicely with fedify @hongminhee

I have a question about the conversion of as:Place properties to the geo: uri scheme cause I am pretty bad at math.

Can we convert geo: `Uncertinty` to as:accuracy ?
https://en.wikipedia.org/wiki/Geo_URI_scheme#Uncertainty

And:
The most compact representation would be geohash again but then we might loose some precision if it is "certain".

E.g. the link
geo:37.786971,-122.399677;u=35?info=a

is normalized to a kv key array (like any link by user/pw, host, pattern or path, parameters, hash, search etc.)

resulting in e.g.
2|9q8yywzm0ccy|;35|?info=a
but reversed then to

geo:37.78697108,-122.39967691;u=35?info=a

[semantically ok cause uncertainty but not strictly equal]
But can we calc what uncertainty means e.g. 1 floating point of the coordinates?

btw: enums, using fedidb for constant host shorts, most popular have then 1 byte, then 2 :)
