You are mostly right, except that in addition to the same license, the Share-Alike provision in the OSM license (the ODbL [0]) also enables derivatives to be re-released with "A compatible license." I am not a lawyer, but I would assume someone at Overture has deemed their license (the CDLAv2 [1]) to be "compatible" with ODbL. (edit: From the link in OP, the OSM-based data is being released with ODbL. I think I'm wro…

CDLA Permissive is not downstream compatible with ODbL. ODbL is a sharealike licence, CDLA Permissive (as the name suggests) isn’t. Overture can’t relicense OSM-derived content under CDLA Permissive. From a brief skim of the landing page, it looks like the OSM-derived content is not being offered permissively. See https://overturemaps.org/download/ .

You're right, I was mistaken.

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-…

Another bit of context: OSM mappers were quite discontent with edits of many of Overture members. Be it low-paid contractors or bulk importing stuff that AI derived from satellite imagery.

I like that they provide this data, however when you try to actually retrieve it, It looks like they went out of their way to make it as convoluted as possible to try to retrieve any of the actual data.... so you have to use DuckDB and then do the import using that? why not just support mysql dump files? why require someone to have DuckDB? is DuckDB that popular? also the links they provide don't work so it doesn't l…

yeah, I thought about mentioning that it's kind of rude to lock that data behind AWS or Azure accounts, but realistically no one can be surprised that Big Cloud Providers want people to use more big cloud services

There's nothing stopping either AWS or Azure from granting `s3:Get` and `s3:List` on those buckets to enable unauthenticated reads, if they were thus interested

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 clou…

So one Lambda execution per tile?

Like the other comment says I don't think it's quite that bad but also CloudFront (or whatever CDN you use) is going to cache the response. In my case I'm rendering restaurant locations on a map. I only have X number of items that each have a map of the restaurants they are available at so unless people pan/zoom around a lot I only expect a handful of lamba calls and the resulting tile data will be cached in CloudFront for everyone else.

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.

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-time traffic.

The OSM ODbL is crystal clear that OSM contributors have to be credited. I don't believe that CDLA Permissive v2.0 magically allows Overture to bypass it.

--EDIT: I missed that they're using different licenses per dataset, the transport theme is OBDL, which I'm sure will trip up users who are not careful.

Overture could be seen as hostile to OpenStreetMap, but I do not think they are washing any licenses here. The article explicitly says that the CDLA license applies to data provided by Meta and Microsoft, not data from OSM. I think it's unfortunate that Meta and Microsoft aren't contributing their data to OSM instead of releasing it under a different license, but c'est la vie.
