MapLibre Tile (MLT) debuts as a successor to the Mapbox Vector Tile (MVT) format. It's built from the ground up to handle massive geospatial data volumes and next-generation source formats like Overture Maps. The design focuses on leveraging modern graphics APIs for high-performance rendering of planet-scale basemaps.

MLT promises major efficiency gains, offering up to 6x better compression on large tiles through a column-oriented layout. This reduces storage costs and improves cache utilization. The format also delivers faster decoding performance, making it suitable for demanding applications where low latency is critical for user experience.

Currently, both MapLibre GL JS and MapLibre Native support MLT sources. Developers can try it today by setting the encoding property to `mlt` in their style JSON. The project is open-source, with backing from Microsoft and AWS, signaling strong industry support for this new standard in the mapping ecosystem.
