Austrian Hill Climbs — road gradients measured by LiDAR

Road climbs across 9 Länder of Austria, measured on the national 1 m airborne-laser terrain model (BEV and the Länder) and ranked by the steepest 25 m — part of the HowSteep survey. What the survey is, and how to read a gradient ladder →

Surveyed here: the great pass roads and the village ramps alongside the steep lanes only the locals knew, found by the same systematic search that produced the UK catalogue.

Every climb here carries a surface and access chip from GIP.at, Austria’s official transport graph, cross-checked with OSM; a road the graph opens to bicycles but not to motor traffic (forest and alp roads) ranks with that restriction stated. Where a check is still pending, the page says so.

4394 climbs published · 1105.7 km of total ascent (a rough total — it adds every small rise in the unsmoothed 1 m profile, noise included) · Burgenland, Kärnten, Niederösterreich, Oberösterreich, Salzburg, Steiermark, Tirol, Vorarlberg and Wien · share

Ranked by one steepest window, a row may be a brief sharp pitch or a sustained traditional climb — the Length and Overall columns tell you which.

≈ measured under tree canopy or near a structure at that window — the value stands but is less certain — the flag does not say whether the true value is higher or lower. Rankings include evidence quality A and B only; every row carries its surface chip, and restricted-access roads (toll/park) carry a controlled-access note — a real road lists, with its restriction stated.

Largest net rise

Net rise is the endpoint elevation difference; total ascent counts every metre climbed, including dips regained — and, since it adds the small rises of an unsmoothed 1 m profile without ever subtracting, read it as indicative rather than surveyed (why).

Provisional measurements

Measured by exactly the same method, but the evidence quality sits below B — usually short-window maxima steep enough to trigger the plausibility review, awaiting a closer look. The numbers stand as measured; treat them as provisional until reviewed. What the evidence-quality letters mean →

Road status under review

Measured like everything else, but these roads are absent from (or barely touched by) the GIP.at graph — usually a forest or farm track, a private drive, or a map phantom. The class sits out of the rankings until verified — each one returns as evidence clears it. Pages stay live and honest.

…and 2,010 more roads under review — see them all in the catalogue.

Restricted roads rank too — with their restriction stated

130 roads open to bicycles but closed to general motor traffic (forest and alp roads, toll roads) are fully measured and rank in the tables above — a real road lists, with its restriction noted rather than silently ranked away. Their rows carry a controlled-access note (fees, gates, seasons) and each page has the details.
