Layer Opacity

Combine OpenStreetMap layers for Manhattan with a semi-transparent GeoJSON layer of neighborhood boundaries on top.

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

  • OSM and GeoJSON sources in one spec
  • per-layer opacity
