> bulk importing stuff that AI derived from satellite imagery. That's a thing? This must explain why Google Maps turned into shit over the last few years. Google seems obsessed with replacing humans with half-assed automation.

Yes, indeed. Google AI mapped skylights (roof windows) on a shopping mall near me as buildings.

In my city they made several buildings that overlap a river, and several more that overlap each other. It's been like that for at least 3 years.

It's unclear to me how Overture manages to "license wash" OSM data here. > Transportation: The OMF’s Transportation layer represents a worldwide road network derived from data in the OpenStreetMap project. This community-built data has been recast into the Overture data format which provides consistent segmentation of the data and a linear reference system to support additions of data such as speed limits or real-tim…

Seems that any new data generated out of Overture Maps could be uploaded to OSM if they chose to do so? The CDLA license is permissive;

My read is that they're not going to avoid credited OSM, but rather they're going to credit OSM / maintain the license for the parts they use from OSM and then the rest will be CDLA 2.0 licensed for anyone to use.

What's the difference between this and Open Street Maps?

In some ways OSM is more impressive than Wikipedia. There’s a gravel path near my house that maybe sees 20 people using it daily. Due to some work done nearby, the path was partially moved a few meters to the side. OSM reflected this new reality the day after.

This really depends on the density of contributors. In Paris every single tree is mapped on OSM, while in more remote areas it’s not rare to see entire roads or even villages missing.

> There is the occasional vandalism edit that simply can't be shown to an end-user. I remember the same sort of arguments being made about how web sites could not possibly ever accept user comments or submissions, or could not ever risk having users sending links to one another. Those all proved to be false.

Editing OpenStreetMap isn't quite equivalent to commenting on a post. OSM allows you to edit anything, which is fantastic but also allows for more serious vandalism. We have seen major cities renamed to racial slurs, for example. As with Wikipedia, the community is generally very good about correcting these issues quickly. It's an uncommon problem that a lot of people work to mitigate. But I stand by what I said: van…

Once in 19 years, I think?

It’s not great but let’s not pretend it’s more of a problem than it is.

Could also be that OSM leverages an open data set.

If my French doesn’t deceive me, https://opendata.paris.fr/explore/dataset/les-arbres/informa... has data on 207,688 trees, tagged with species, height, and circumference.

> Administrative Boundaries: A global open dataset of national and regional administrative boundaries, this boundary data includes regional names which have been translated into over 40 different languages to support international use.

Oh that is going to be fun. If I recall correctly Google Maps alters the boundaries of places based on the views of the location the map is being requested from to avoid getting in the middle of disputes.

Not "correctly" showing boundaries is a crime in many countries.
