Subject: MLT vector tile format
The Gist: MapLibre Tile (MLT) is a new vector tile format intended as a ground-up successor to Mapbox Vector Tiles (MVT), targeting planet-scale 2D/“2.5D” basemaps and modern graphics APIs. It aims to reduce tile size and speed decoding via a column-oriented layout plus lightweight, recursively applied encodings that can take advantage of SIMD. Current implementations are described as feature-parity with MVT with one noted exception, and the spec is designed to grow toward better 3D/elevation support and richer attribute types.
Key Claims/Facts:
- Compression & layout: Column-oriented storage with custom lightweight encodings, claiming up to ~6× compression on large tiles.
- Faster decode: Encodings are designed to be fast and SIMD-friendly for improved decoding performance.
- Ecosystem readiness: MapLibre GL JS and MapLibre Native support MLT today via a style
encoding: "mlt"; tooling includes an on-the-fly MVT→MLT “encoding server” and upcoming/available producer support (e.g., Planetiler).
