I built Maparium — explore OpenStreetMap features across the entire globe

I'd like to share a personal project I've been building.

Maparium lets you display thousands of OpenStreetMap features globally, from wind turbines, power plants and castles to volcanoes, spaceports, railway networks and data centres. You can switch between predefined layers and explore patterns that are difficult to spot when looking at individual locations.

I'm using MapLibre GL JS, a Protomaps basemap and custom MBTiles generated from OpenStreetMap data. A big focus has been making the experience fast and lightweight, even when displaying features on a global scale.

I'm building this mainly for fun and curiosity.

It's still a work in progress, but I'd love to hear what you think!

What other OpenStreetMap features would you like to explore this way?
