link roads missing from a generated map

[andrey-abstracted]

motorway_links and primary_links are present on OSM maps but missing when a freshly generated map is viewed using PMTiles viewer.

In protomaps-basemap-opensource-20230408.pmtiles primary_links are present but motorway_links are not.

The screenshots are from the freshly generated map viewed using PMTiles viewer.

Thanks, I can verify that this is an issue in specific cases where links consist of multiple ways, working on a fix.

PR https://github.com/protomaps/basemaps/pull/57 is progress towards improving this, but the logic in LinkSimplify needs to change to handle more complex cases like the 2nd.

Great, thank you. On a slightly irrelevant note - would it be possible to change the zoom range for motorways from 12-15 to 11-15. That feature is quite a significant visual landmark and is still visible at lower zoom levels.

@andrey-abstracted a major rework of both the display style and base tileset is coming soon; The best option for right now though, and in the future, is to generate your own tileset while modifying the configuration to your needs. This will likely require a small modification to both Java code and JSON styles.

Our goal is to make this kind of adjustment easy via configuration changes and/or style parameters, but that is a medium to long-term project.

@bdon yes, absolutely, I've been doing that. In this particular case it felt like a better user experience but that is of course quite subjective.

I think this one can be closed as complete (link simplify bug).
