# Builder overview

> geolith builds protomaps-compatible PMTiles vector tile archives and the .glx geocoding index from Overture Maps and OpenStreetMap data, at planet scale, in Rust.

The geolith builder is a Rust program that turns Overture Maps and OpenStreetMap data into two artifacts: a PMTiles vector tile archive that follows the Protomaps basemap schema, and the `.glx` geocoding index that [geolith Search](/search/hosted/overview) answers from. One build writes both, so names on the map and names in search come from the same data.

## How it works

- [Pipeline](/builder/architecture/pipeline): read, transform, merge and write.
- [Modules](/builder/architecture/modules): the crates and what each one does.
- [Ecosystem](/builder/architecture/ecosystem): the tools that read what the builder writes.
