Every climb on one map
All 21,803 published climbs — the UK, the US, Switzerland, Austria and France on one map (3,487 in this country) — coloured by their steepest 25 m. Click a dot for the climb’s page; the buttons below re-frame the map on another country. Coverage follows the open LiDAR record — an empty region usually means missing data, not missing hills.

The interactive map could not load (the map library or the basemap tiles are unreachable). The survey’s own picture of the same climbs:
The two optional layers show the survey behind the pages: profiled roads carry a full measured gradient ladder but sit below the page cutoffs (or await review); coarse-only candidates passed only the 50 m screen — unverified, some will be terrain-model artifacts. Both are drawn as hollow rings (○ profiled, ○ coarse), never as filled dots: a filled dot is always a page, and its colour is always the 25 m gradient, on this map and the US one. Together they are the ~54,000 roads measured so far; the map is a picture, the tables are the product.
Coverage footprint — shaded ground is where the survey holds open 1 m LiDAR and has screened every public road: England and Wales as national composites, Scotland where the national programme has published so far, Northern Ireland’s river-basin surveys. Unshaded ground is where no open 1 m LiDAR was in the record when the survey ran: not “no hills”, not yet measurable. The footprint is computed from the survey’s own tile archive, never asserted.
Filled dots are climb pages. Dot colour: ● <15% ● 15–20% ● 20–25% ● 25–30% ● 30%+ — steepest 25 m window, the same figure the tables rank by. A grey-blue or blue dot is a page that earned its place another way (a long climb, a big total ascent, a listed or founding climb) — the same rule in every country.
