Shobrooke to Uppincott°

Shape: sustained — 35% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 65 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 (50.7992, -3.5976)'). 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.

| Window | Maximum | Located at | |
|---|---|---|---|
| 2 m (diagnostic) | ≈55% | 433–435 m | under overhead cover |
| 3 m (diagnostic) | ≈55% | 433–436 m | under overhead cover |
| 5 m | ≈46% | 433–438 m | under overhead cover |
| 10 m | ≈36% | 428–438 m | under overhead cover |
| 20 m | 26.0% | 428–448 m | |
| 25 m | 23.9% | 423–448 m | |
| 50 m | ≈18.7% | 411–461 m | under overhead cover |
| 100 m | ≈12.8% | 376–476 m | under overhead cover |
