The pipeline reads GPX files, applies a naming convention, sanitises coordinates (Kalman, LOESS, Gaussian kernel or Savitzky-Golay smoothing, and red flags for implausible readings), resamples the trajectory to a uniform spatial resolution derived from the Nyquist criterion, and replaces elevation with values from a Digital Elevation Model. Derived measures include speed, slope, elevation gain and kilometre-effort, Tobler hiking function parameters fitted by quantile regression, comparison between streams, detection of passes along a route and map matching to a known reference trail by dynamic programming.
