So ganz akkurat ist die Zählung leider nicht, aber gut 400 #Hydranten sind es dann doch!
While contributing a little to #OpenStreetMap today (which you have to create an account for) I kept seeing edits from another user in my area, making me guess that they probably gotta live in the same hood as me. That made me wonder if you could use #OSM contributions for #OSINT, in particular for #geolocating contributors.
And yes, of course you can!
OSM states in their #privacy policy that email addresses are never ("intentionally") published, however your user name is public and searchable. So I gave it a little test, I picked a random OSM contributor and based on how their edits are clustered on the map I could make a reasonable guess about the neighborhood they likely live in, see screenshot below. Searching their user name on the web I could quickly identify other accounts on Github and social media, as well their OSM contributions, meaning this works in both directions.
So, while obviously I don't want to discourage anyone from contributing to OSM, I do recommend using a user name that's not easily linkable to your accounts on other websites as well as a unique email address, as you never know if there'll be a leak someday.
Das ist heute sicher der 50. #Hydrant, den ich in die #OpenStreetMap eintrage...
Man kann doch sicher eine #Overpass Query bauen, die alle Hydranten in Augsburg auflistet, die ich gemappt habe, oder?
Muss ich definitiv mal machen!
Did some outdoor "#OSINT" today checking shop opening hours, vacancy status and other publicly available information in person, and even measured widths of streets and entrance gateways for #OpenStreetMap. It's a really fun pastime, you get to explore your neighborhood a bit more thoroughly, have a nice walk and casually contribute to a great project at the same time. Absolutely recommend it and the #StreetComplete app makes it super easy to become part of #OSM.
13/ One final bonus toot - we would be remiss not to mention the absolutely thriving Indonesian #OpenStreetMap community (their local organisation is known in Indonesian as "Perkumpulan OpenStreetMap Indonesia" which yields the delightful abbreviation "POI").
Sadly they don't seem to be active on the fediverse
