Redesmouth to Woodcock Hill°

Shape: sustained — 38% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 169 m.
Found purely from mapping and LiDAR data, and not yet matched against books, race records or lists — it may be well known to locals under a name we've never heard. It was cross-checked against the OS road network, surface models and map tags, but a discovery can still be an artifact of the terrain model or the map. Treat it as a well-evidenced hypothesis until someone has ridden it. If you know this road, tell us what you found — photographs, corrections and local knowledge all welcome; the map links below let you scout it first.
° The name is provisional: this climb is not yet matched to a documented name, so it was named from nearby map places. There is no evidence of local usage — (auto-named from gazetteer (hypothesis, unreviewed); discovered as 'Discovered lane (55.1344, -2.2119)'). Corrections welcome.
≈ Overhead cover (tree canopy or structures) spans 6% 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.
Gradient ladder what do windows mean?
| Window | Maximum | Located at | |
|---|---|---|---|
| 2 m (diagnostic) | ≈40% | 2–4 m | under overhead cover terrain reads 109.7% at 364–366 m across a structure — excluded |
| 3 m (diagnostic) | ≈37% | 1–4 m | under overhead cover terrain reads 107.4% at 364–367 m across a structure — excluded |
| 5 m | ≈33% | 0–5 m | under overhead cover terrain reads 97.3% at 363–368 m across a structure — excluded |
| 10 m | ≈26% | 0–10 m | under overhead cover terrain reads 57.2% at 360–370 m across a structure — excluded |
| 20 m | ≈23.0% | 217–237 m | under overhead cover terrain reads 29.0% at 360–380 m across a structure — excluded |
| 25 m | ≈22.1% | 213–238 m | under overhead cover terrain reads 23.5% at 360–385 m across a structure — excluded |
| 50 m | 19.4% | 211–261 m | |
| 100 m | 15.7% | 194–294 m |
