Field notes
Route data can include longitude, latitude, and ground elevation, along with turn instructions that inherit street names for unnamed sidewalks and crosswalks. The response also carries deterministic engine-version and map-timestamp metadata for judging whether a cached route is still current. The site says it leaves missing OpenStreetMap attributes null instead of inferring values such as speed limits or path widths.
