{"about":"The vertical profiles of the 12 axes of the Granville Bridge, copied from urbanstyle's data/bridges-measured/granville-bridge.bridge.json (format urbanstyle.bridge/1, made 2026-10-12). Heights are metres of the deck top above the bridge's reference ground. They come from the City of Vancouver LiDAR 2022 (open data, Open Government Licence - Vancouver): the deck top (the 25 % quantile of the deck returns) at a station every 10 m along each axis. `points` and `curves` are the fit of the stations: grade points [s, z] and the length of the vertical curve at each point.","source":"City of Vancouver LiDAR
