MVT Wrangler

A high-performance CLI tool for modifying Mapbox Vector Tile (MVT) archives with spatial and attribute filters.

We use this at KotobaMedia to make a Japan-oriented variant of Protomaps' tiles generated from OpenStreetMap without having to download and reprocess OpenStreetMap data from scratch.
