| USGS lidar, 1 m | 1,941m | reference |
They differ because a GPS file picks up noise on every wiggle and often takes its heights from a coarse terrain model, while lidar maps the ground itself to about a metre. We sampled this route every 30 m against USGS 3DEP and counted each rise of 3 m or more, on Oct 26, 2026. The planner still uses the course file.
