Open‑source mapping has just had a break‑out year. This talk surveys the latest developments across MapLibre, OpenStreetMap, Overture Maps, and Protomaps, showing how contributors and developers can participate in building a truly independent, production‑ready mapping stack.

Highlights include:

• Major performance improvements in MapLibre’s core renderer
  * The release of Martin v1.0, a high‑speed vector tile server
  * New ready‑to‑render tile layers and extraction tools hosted by OpenStreetMap US
  * Expanding community programs, global microgrants, and initiatives supporting open‑source geodata

Attendees will learn how these projects fit together, how to contribute, and how open‑source mapping is rapidly becoming a powerful alternative to proprietary map platforms.

Target Audience:

• Developers
  * Open‑source enthusiasts
  * Map enthusiasts
