people kept asking for pmtiles merge, now there is pmtiles merge, inevitably they will ask why it refuses to work for overlapping inputs, here is why merging tilesets is hard (blog post):

New CLI feature: pmtiles merge

The pmtiles CLI now includes the highly requested merge command for combining multiple tilesets into a single archive. As an example use case: the Mapterhorn project distributes several archives: planet.pmtiles for the full planet terrain mosaic, from zoom levels 0 to 12. 6-20-28.pmtiles, 6-21-29.pmtiles, etc for zoom 13 and above in specific areas. These archives can contain up to zoom level 17. These archives are split to ensure each one is at most a few hundred gigabytes: the total size of al

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 anything - just upload your PMTiles to any cloud storage, set up CORS, and deep link to the file on pmtiles.io using embedded URL parameters. pmtiles.io got a re-write! It now features: Light UI mode support for viewing TileJSON (ZXY endpoints) in addition to PMTiles.

New blog post on @mapterhorn@mastodon.social - terrain for web mapping

Mapterhorn - Terrain for Web Mapping

The Protomaps project is the PMTiles format, its tooling, and a 120GB basemap vector cartographic tileset created from OpenStreetMap and other open data sources. PMTiles is not limited to storing vector data - it’s also used for raster data, like scans of historical paper maps. Mapping apps often don’t just need to show vectors of buildings, boundaries and places. Some apps need elevation data, since interesting places on Earth aren’t flat!

Replying to
Please someone discover a new data structure or compression algorithm that makes PMTiles v3 obsolete, that would be amazing
