On-device, open source mobile vector rendering of OpenStreetMap
summary
Mapbox announces an on‑device, GPU‑accelerated renderer that draws OpenStreetMap data as vector tiles on Android and iOS with a C++ core and platform bindings, plus a separate JavaScript WebGL variant. The toolchain uses Mapnik and tilelive to bake and simplify geometry, a JSON style specification for smooth zooming and label collision, and runs live on devices (iPad, Nexus 9). Project ships hundreds of open source components across almost 500 GitHub repos and leans on two million OSM contributors.
