tools: steep_segments.js — extract steep bike-track sections to GPX + brouter
Two-pass extractor for the steepest sections of recorded bike tracks: - pulls gps_points/gps_sessions from baldav.db (adb run-as), bike only; - refines elevation online (--gpxz Copernicus GLO-30 with the user's key, deduped to ~33m cells + cached; falls back to open-elevation / on-device altitude_srtm_m); - distance-window smoothing, grade over a configurable base (default 120m) with a GPS-gap guard, keeps the steepest base-window core per section (so a real steep core is not averaged away by a long gentle stretch), spatial de-dup of repeats; - outputs steep_segments.gpx (named by grade/length/drop) + a brouter lonlats string. Verified against two ground-truth spots the rider confirmed; open-elevation/SRTM30 flatten short steep features that GLO-30 resolves. Key + data stay gitignored.
