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

• only queryArea and the extract change between cities

This example comes from the autk-grammar repository.
