On-device, open source mobile vector rendering of OpenStreetMap

Accepted Session
Short Form
Scheduled: Tuesday, June 23, 2015 from 10:00 – 10:45am in B304


Learn about the moving pieces of Mapbox GL, an open source framework for rendering beautiful maps based on OpenStreetMap-based data on Android and iOS. Find out what goes into making completely configurable world maps that are always up to date and always available in your pocket.


Mapbox GL is a completely open source framework for turning OpenStreetMap, and other, map data into beautiful, device-rendered maps. This means that the style can change at 60 frames per second, including when offline. Come learn about the pieces that go into this stack, from vector “tiles” of map data, to low-level rendering, on to developer APIs and eventually, apps. We’ll have plenty of demos on Android and iOS to show off the capabilities.
