Vector tiles

Vector tiles are something that is still not in the mainstream, but they are more flexible than raster tiles:

https://wiki.openstreetmap.org/wiki/Vector_tiles

We have some vector tiles with OSM data already even in production. Most common use are mobile apps (like OsmAnd, Maps.me or Yanosik). Some other examples are vector tiles being internally (server side) converted into raster tiles, like the maps served by Thunderforest:

There can be however client side rendering used on the desktop, for example multilingual Belorus or India maps:

You can also play relatively easy with local vector tiles server:

There are multiple software solutions (and problems) for serving and rendering vector tiles - there's a nice overview made by Paul Norman:

For me the biggest challenge now would be to move the standard tiles layer into vectors internally (just like in the Thunderforest case):

Re: Vector tiles

Vector tiles can be useful not only for map rendering. There's a project accepted for GSoC - Vector Tiles for iD Editor:

Re: Vector tiles

Paul Norman has just announced new vector style called Bolder:

https://www.openstreetmap.org/user/pnorman/diary/43814
https://github.com/pnorman/bolder

It is a candidate for osm-carto migration, but there are still many moving parts, so expect no immediate results.

[UPDATE:] Bolder is unrelated to osm-carto vector migration. It's just a new, client-side vector style using the same database schema as osm-carto.

Re: Vector tiles

There's a discussion on the OSM Carto issue ticket about migrating to vector tiles:

Re: Vector tiles

Interesting article and tool from Mapbox - "Millimeter precision HD Vector Maps":
