Many of the maps you see created from OpenStreetMap data use the battle-hardened mod_tile software stack to render images on-demand directly from a PostGIS database. To work around some of its inherent limitations, Andy started working on an alternative approach based on the mapnik-vector-tile software, storing the map data in protocol-buffer based vector tiles. This opens up a range of cartographic features, from faster map drawing times to easing the burden of hosting multiple styles.

Andy will discuss the approaches taken, the pitfalls encountered and the future possibilities made possible using this vector tile approach.
