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-…

How do they do that? I thought OSM was licensed in such a way that if you combine it with other data, the whole thing needed to be released with the same license?

Great stuff, at some point I feel like Google is going to have to try to extract even more revenue out of maps than they currently get and it will really empower these sorts of collaborative map systems.

I wish there was a way for people to fund satellite imagery that got pushed into these systems after purchase. Sunnyvale, for example, paid for a lot of imagery of the city that they use/used in staff discussions about traffic, zoning, etc. It would be nice if they could then push those images into the open data set.

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 wrong about license compatibility. Again, not a lawyer.).

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?

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/.

> 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…

Seems like a play at the old Microsoft "Embrace, Extend" approach. Whether or not there's an Extinguish after that is yet to be determined.

These things don’t matter when one side has 100x the lawyers of the other side.

> 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! [0] https://github.com/alltheplaces/alltheplaces/issues/5133

Sadly copyright and copyright-like restrictions are really complex. I am not 100% entirely sure whether concerns that I raised in this issue are really problematic, but...

Are they releasing OSM data or OSM derived data on CDLAv2 anywhere?

It shouldn’t be required if the range requests are right and you have a compatible renderer in the client.

To expand a bit -- There are adapters for mapbox(gl/libre) and leaflet, and so on that will allow you to use a .pmtiles directly from the client with a range request supporting server, like s3 or nginx.

I've used protomaps basemaps to generate an Ireland and EU basemaps for a project from OSM data. I still haven't quite figured out the tuning for which features should be shown, combined, or excluded yet, and the generated layer names are sort of, but not quite compatible with similar base layers + styles from mapbox (which uses the same base data, but a different, proprietary conversion). This part takes a reasonable skill as a GIS person and some taste in the design of the feature symbology.

The downside of doing this on S3 directly is that you might wind up publishing a link to a 100 gig file that would cost $10 if someone just downloaded it. Lambda invocations seem cheap compared to that risk. OTOH, throwing it on a hetzner box is quite reasonable.
