Description:

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.
