This talk presents a FOSS stack for building, rendering, and using OpenStreetMap vector tiles. Ascend Maps ( https://github.com/styluslabs/maps ) is a cross-platform application for interactive maps. It is extremely customizable, with hiking, cycling, and transit views for the base map, user-editable sources, styles, and shaders for custom maps and overlays, and plugins for search, routing, and map sources.

tangram-ng ( https://github.com/styluslabs/tangram-ng ) extends the Tangram ES map engine originally created by Mapzen, adding support for 3D terrain, embedded SVG, and additional raster formats, along with substantial performance and stability improvements.

geodesk-tiles ( https://github.com/styluslabs/geodesk-tiles ) builds vector tiles on demand from a GeoDesk library, making it possible to start serving tiles for the whole world instantly.
