All 22,848 published climbs — the UK, the US, Switzerland, Austria, France and New Zealand on one map (699 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:
Coverage footprint — shaded ground is where the survey has screened the LINZ Topo50 road network against the national 1 m LiDAR terrain model (Toitū Te Whenua Land Information New Zealand). 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.
