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

OpenStreetMap is community of people creating fully open map database. From roads, shops and rivers to tourism attractions, hiking routes and hospitals, with all kind of detail. Anyone can contribute (and as someone quite involved in OSM: if you want to map something, especially area near you: you are welcome!).

Overture is a new group of companies releasing some datasets on open licenses, but methods used to create them remain proprietary. Some of released data is theirs, many datasets are repackaged OpenStreetMap data.

> 2. There is no published tooling for how someone else can reproduce the same data. This is true, and is actually the whole point of Overture. Overture was developed to enable private companies to leverage open data (like OpenStreetMap) but also combine it with their proprietary data and processes. The intention is to share the result with a relatively permissive license (a new thing called the Community Database Li…

Wouldn't the closed processes and underlying data severely limit communities such as OSM from using Overture Maps results for anything other than a validation of what OSM already knows from other sources? Perhaps Overture Maps has used impressively accurate satellite imagery tracing to detect the demolition and rebuild of a structure somewhere in Sudan, and can output a new polygon. No OSM mapper is setting foot in S…

These are all valid questions, and commonly raised concerns, about the Overture Project.

If you are looking for maps themselves (a la Google Maps) I highly recommend checking out Protomaps [0]. It provides a single file (PMTile format) that contains all the map data and you can request ranges from the single file to get the required vector data you need for a given area/zoom.

So you can setup something like the following:

    S3 (host the myfile.pmtiles) 
Then you can setup tiles.mydomain.com (or use the cloudfront domain directly) and then use Leaflet or similar on the frontend to fetch/render the tiles. For Leaflet you use the protomaps plugin/lib and give it a url like "https://tiles.yourdomain.com/20230408/{z}/{x}/{y}.mvt" where "20230408" maps to "20230408.pmtiles" in your S3 bucket. Now I can drop new pmtiles files into that bucket and update my clients to use the new source. And since the tiles are in vector format you can theme them however you want in the client which is neat. Lastly you don't have to use the 100+GB whole-earth tileset. You can use a tool [1] (provided by the same guy) to download a dataset for just a given geographical region.

The .pmtiles file is a little over 100GB but the whole setup took me only an hour or two max to get running and will cost way less than Google Maps to run.

For context, Overture Maps is a project that intends to enable large players in the geospatial space (TomTom, Amazon, Microsoft, but notably _not_ Google) to leverage open data sets (OpenStreetMap among them) alongside proprietary data and processes that they own. The consortium intends to enable a framework for enhancing geospatial data based in open data sets (e.g. OSM) with their own proprietary processes, and re-…

I came to ask for this info so thanks for the succinct summary!

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.

Yes, exactly. Overture is, for better or worse, looking to create a dataset that is more difficult to mess with / contribute to. I'm big on OpenStreetMap, but I can't deny its a bit of a liability for Facebook and other companies that display maps to their users. There is the occasional vandalism edit that simply can't be shown to an end-user. Facebook put significant effort into maintaining a moderated version of th…

> It would be so cool to see AllThePlaces integration into RapID for example, if there isn't already(?) Part of the problem is not entirely clear copyright/copyright-like status of this dataset. Thanks to https://en.wikipedia.org/wiki/Database_right and similar things (in general OSM is really careful with legal status of datasets being imported).

Ah, great catch. After posting my comment I came across this GitHub issue that touches on this point as well [0]

As always, I will be vigilant about checking licenses before adding data to OSM!

their demo isn't doing them any favors since it seems to stop at some random zoomlevel, eliding the kind of detail that I'd care about if I were evaluating that solution

digging into their GH repos surfaces https://protomaps.github.io/PMTiles/?url=https%3A%2F%2Fr2-pu... which is at least more detailed if not quite a GMaps killer

The GitHub repo is here; https://github.com/OvertureMaps/data -- Licenses look super permissive - I'm not that familiar with the state of Open Mapping but the GERS idea looks great too. https://docs.overturemaps.org/gers/

The CDLA license feels like NIH... but at least it looks genuinely permissive, as opposed to fake open source.

Curiously, two of the four layers use the ODbL.

> 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: vandalism on OSM is in many cases unacceptable to show to end-users.

The OSM basemap is used in many official publications, in many social media applications, etc. I'd actually recommend using the basemap for most simple mapping cases, as long as it's being continuously updated from upstream (or, it is the upstream basemap). If you take a snapshot of that data, however, you risk capturing some bad stuff. That is a real risk for a company like Meta.
