Compute on OSM Roads

Run a WGSL function over OpenStreetMap road segments to fill in missing lane counts, then color roads by lanes.

Live Playground

OpenStreetMap data

This spec reads a pre-downloaded OpenStreetMap extract through pbfFileUrl, so it loads in seconds. Remove pbfFileUrl to query the Overpass API live instead, which can take several minutes because Overpass is rate-limited.

Highlights

  • multi-line WGSL with a conditional
  • compute over an OSM layer table

This example comes from the autk-grammar repository.
