Distance is measured along the mapped OpenStreetMap line.
Elevation comes from SRTM 30 m samples roughly every 250 m; ascent ignores changes under 5 m to damp noise.
Walking time uses Tobler's hiking function over the elevation profile.
Difficulty uses the SAC scale when mapped; otherwise distance plus 1 km per 100 m of ascent (under 10 easy, under 20 moderate, under 35 hard).
