In the past I made a map of train lines in and around Prague, which required quite a complex stack, since the information I wanted was in relations. How does Protomaps deal with relations?
It can deal with relations more flexibly than PostGIS-based workflows, because the tiles are generated from a near lossless representation of OSM instead of having to convert to OGC Simple Features first.
Can you email me at brandon@protomaps.com with what specific tags and relations you are interested in? I want to support transit layers as part of basemaps and ideally this is an option when generating a PMTiles archive.
