Strynefjellet (Rv 15) from Hjelle

25234.0 m · net rise 1505.0 m · overall 6.0% · evidence quality B (good) · Stryn · Vestland

Shape: stepped — 49% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 1032 m.

Not yet matched against documented climbs — the measurement stands on its own.

≈ Overhead cover (tree canopy or structures) spans 12% of this route — detected by comparing the surface model (DSM, treetops and rooftops) against the terrain model (DTM, bare ground). Under cover the bare-ground model is built from fewer laser returns, so metre-scale readings can wobble; maxima whose window sits in a covered zone are marked ≈ below — less certain — the flag does not say whether the true value is higher or lower. Longer windows average over more clean ground and are steadier.

This climb's data: OCL JSON — the full gradient ladder, quality flags and provenance in the OpenClimb Ladder format.

Surface: paved (0% unpaved), according to NVDB, Norway's National Road Database: paved for the first 14,894 m; off the road model from 14,894 m to 15,464 m; paved from 15,464 m to the top.

Pending human review: about 49% of this line (0–25234 m) runs through tunnels or covered galleries, where the laser reads the hill above and not the road. Tunnels are never the source of a published number, so the covered stretch is left out of the window figures and the total ascent, and a page that is mostly underground is listed, not ranked.

Measured, not vetted. This page records what the laser record shows about the road's shape — nothing more. Nobody has necessarily ridden or inspected this road for the survey, and a page here is not a recommendation and no guarantee that the road is open, surfaced, rideable or safe. Gates, private sections, missing rights of way and hazards do not show up in elevation data. Check access and conditions on the ground and make your own judgment.

Profile

The map, profile and gradient chart share one position — move your pointer over them and the marker follows. Colors are the gradient bands; the shaded span is the steepest 25 m. Any 25 m figure is good to about a point either way (why).
