I'll also share some latest developments using @protomaps.com and @maplibre.org to self-host vector maps with custom layers, beautiful rendering and seamless zoom, in case you are interested in that type of thing 🗺️

mapgl for #rstats supports @protomaps.com PMTiles as a data source in both @maplibre.org and @mapbox.com maps.

If you need to visualize large datasets but struggle with hosting / infrastructure requirements, PMTiles may be exactly what you need.

Have you been waiting for "Protomaps Terrain"?

It's arriving! @mapterhorn.com is an independent project created by @oliverwipfli.ch - a global elevation model built from multiple sources, distributed as a single PMTiles archive

Added a section to the PMTiles docs on fast uploading to @source.coop using only the pmtiles single binary CLI:

docs.protomaps.com/pmtiles/clou...

Easier to install than awscli or rclone - just bring your repo credentials!

I'd like to give a big thanks to @protomaps.com for their fantastic work. Our open source Android port of Soundscape, the navigation and exploration app for visually impaired uses a protomaps server and it's reduced the cost to the supporting charities by a huge amount. github.com/Scottish-Tec...

There's an ongoing issue preventing PMTiles hosted on GitHub Pages from being loaded correctly in Firefox

Issue:

Minimal Reproduction using raw fetch and plain files:

A Tour of the New pmtiles.io

pmtiles.io is an open source viewer for PMTiles tilesets. It’s a great way to inspect tilesets before you publish them on your site or app. It’s also a simple way to share GIS datasets without coding ...

Leaflet 0.8-dev from 10 years ago with a high performance @protomaps.com basemap canvas renderer from 2025? Yes it works 😅
So if you have legacy systems running where you don't have the resources to upgrade you can still replace costly raster tile APIs.
