What's the difference between this and Open Street Maps?
This license-washes Open Street Maps data into proprietary systems so big corps can use it without contributing back.
Overture Maps Foundation releases open map dataset

Re: Overture Maps Foundation releases open map dataset
#92> 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…
Unless you are making a google maps rival, in 99% of cases you won't need those countries with controversial borders.
And unless you have millions and millions of users, no one will care even in those countries.

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…
The transformation of OpenStreetMap features into the basemap is open source and available under a permissive license now at http://github.com/protomaps/basemaps This is the focus of most development for the next few months - like you said, it's also a matter of aesthetics and context, like if the map is underlying another PMTiles data layer it should be lower contrast then if it's overlaid with pin markers. The end…
Yes, that's what I was using for my basemaps, it's quite fast for Ireland on a relatively fast machine (minutes), but Europe as a whole was hours. (hetzner quad core 8 thread ~3yr old intel machine with 64G ram)
I've got a couple of goals, or at least evaluations for goals --
1) Have a stripped down basemap like Carto Light, but with different emphasis for the "bicycling friendly" roads, and selectively higher contrast/emphasis for those minor through roads that discourage car traffic but are perfect for a bike. (e.g. Irish boreens, those 1 lane or double track "paved" L roads that are everywhere outside of the major cities.) I find that I simply can't see the minor roads on apple/google maps when I'm out unless I'm zoomed in to the point that I can barely see a network. (fading eyesight and super low contrast).
2) Another lighter base map, but with transit focused features to compliment some of the open data in Ireland around transit -- the routes and timetables and so on. I'm aiming for a site that can be 100% statically hosted but will show the routes in a more friendly manner than Bus Eireann's site.
3) If it goes well, I might be doing this in a more commercial context for some clients who are currently using mapbox for their basemaps but due to political concerns need to insert in different names/boundaries for disputed areas/features. We'd love to be able to self host, but quality is a major concern there.
The bugs that I'm seeing in the 1 and 2 cases are things like handling the look of freeway interchanges/flyovers at close zooms, consistently getting rivers to show at appropriate zooms because they're into two separate feature types depending on the width, with the narrow bits getting dropped. And the general mismatch between the styling I'm used to from the mapbox converted layer names/feature types and what's coming out of pmtiles/basemaps. The feature bits look like tippecanoe coalesce/drop densest features tuning, but I'm also looking at just dropping out entire feature sets to drop the size of the tiles. That should help the coalesce/dropping behavior as well.

Thanks - for the issues related to freeway interchanges and rivers, it would be most helpful to report these on GitHub using screenshots and links to lat/lon positions, or even links to OSM nodes and ways.
OSM is a freeform dataset and not a cartographic product, so most of the basemap work now and in the future is on getting good results of this transformation for 200+ countries. The mismatch vs. existing maps must exist because we need to ensure to downstream commercial users that all end products of the map generation are openly licensed - that's why this is being pursued as an independent, self-funded project with support from GitHub Sponsors: http://github.com/sponsors/protomaps

Ok, I’ll dig a bit more to get some good test cases with the local data that I’m familiar with, and make sure that it’s not something that I’m doing wrong.

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
I just updated https://protomaps.com it to use the more detailed file you found, thanks. So instead of a zoom level of 12 it should work down to 20+ - the actual dataset contains up to zoom 15, which is ~1 billion tiles in a single 110GB file. It's important to me that I showcase the system working as advertised - you are free to download the 110GB file from that static storage with no restrictions. Unfortunately, th…
I just wanted to say thank you for everything you've done for Protomaps. It was very easy to get started with and other than a small Vue/ES6-related issue I was able to get it integrated into my codebase very quickly.

So one Lambda execution per tile?
Library author here - yes, one execution happens per tile, if you have CloudFront in front those will only happen when the PoP has a miss. With 512MB RAM these generally complete in under 100ms so the unit costs of Lambda are within a few multiples of Cloudflare Workers (.5USD / million invocations)
Hey, want to say I'm super excited by protomaps. I'm struggling a bit to convert existing OSM pbf files into the pmtiles format. Specifically, I'm trying to convert this guy https://daylightmap.org/
Do you have any tips for doing so without renting memory in the cloud?

> We have seen major cities renamed to racial slurs, for example. Once in 19 years, I think? It’s not great but let’s not pretend it’s more of a problem than it is.
No, it's not a huge issue within the OSM community. But surely you see why it's an issue for large companies looking to use the OSM basemap in their projects.
Perfection is an impossible standard to uphold. Even if you do everything in-house, and even if you are Disney, you cannot avoid the occasional scandal:

Re: Overture Maps Foundation releases open map dataset
#99If 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…
Hmm, thats cool, but I need to have raster maps pushed to my endpoints.
Do you know any easy way to use mvt maps and generate tiles from them
on the fly (CGI backend + caching) and then use Leaflet to render those?
I have my own tiny personal project for maps renderer using Leaflet. For now I use 3 sources for tiles (Google, OSM and Esri) but having more sources would be very cool.

I don't personally know how to do that. It appears the PMTiles format does support raster maps but the dataset I use is only vector as far as I know.
