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.
