Ingested from OpenStreetMap relation 357581 (ODbL). The mapped line and 2D length are derived from that geometry. Ascent, descent, and high/low points are sampled from Copernicus GLO-30 (copernicus-dem:glo-30) and remain provisional. Water, permits, and hazards were not taken from OSM tags and must be verified.

OSM 2D length is 62.4 km (relation 357581; network=rwn, operator=Wanderland Schweiz, ref=71). lengthKm is verified: 62.4 km is 2.13% over the official 61.1 km (https://www.schweizmobil.ch/en/hiking-in-switzerland/route-71; ch.astra.wanderland Route attributes (opendata.swiss langsamverkehr-wanderland-schweiz, dataset 2026-02-25, parsed 2026-09-09)). Official km is the ±3% cross-check, not this DataPoint.

DEM high 649 m. GLO-30 cumulative ascent 875 m is the same order as the official 761 m figure (ch.astra.wanderland Route attributes (opendata.swiss langsamverkehr-wanderland-schweiz, dataset 2026-02-25, parsed 2026-09-09)). High point left as Copernicus.

typicalDays 3 is the official SchweizMobil stage count (https://www.schweizmobil.ch/en/hiking-in-switzerland/route-71, checked 2026-09-09), not Math.round(lengthKm/12) and not a duration statute. A calendar season is not published on the federal Route record; it is not invented here.

Water was not mapped to named WaterSource points (no honest atFraction). Villages and inns exist; they were not positioned from an official named list this pass.
