DIY OSM PBF VECTOR TILESNorbert Renner (ikonor)

DIY OSM PBF VECTOR TILESA simple, do-it-yourself solution of generating your own

vector tiles and using them in the Browser with Leaflet - nodatabase and no special vector tile server needed.

WORK IN PROGRESSVery alpha and inefficient right now, so it's slow and might

also crash your Browser.

VECTOR TILES“Vector tiles are a way to deliver geographic

data in small chunks to a browser or otherclient app. Vector tiles are similar to rastertiles but instead of raster images the datareturned is a vector representation of the

features in the tile.”

alternative to the XML formatfile extension *.osm.pbf30% smaller than a bzipped planet6x faster to read than a gzipped planet(not with JavaSript/Browser?)

MOTIVATIONalready global Mapnik Vector Tiles by Michal Migurski

but: optimized for Rendering

I WANT THE RAW THING!as in editors, but larger areain the Browserinteractivity (on hover)

probably will replace with / osm-read ProtoBuf.js
