How this service works
Measures maximum slope for two to ten named European sites and ranks the observed values with ties preserved.
Output
Returns a ranked list of the submitted named sites ordered by their measured maximum slope value, from highest to lowest, with ties preserved using standard dense or competition ranking. Each entry includes the site name, its maximum slope measurement, and its rank position.
Example use cases
Shortlisting steep vineyard sites
“I'm evaluating six potential vineyard locations in France and Spain — rank them by maximum slope so I can identify which sites have steep enough gradient for quality drainage. Here are the coordinates: Priorat (41.19N, 0.74E), Roussillon (42.72N, 2.88E), Rhône Valley (44.93N, 4.82E), Côte de Nuits (47.18N, 4.95E), Douro Valley (41.15N, -7.78E), and Alentejo (38.55N, -7.91E).”
Construction site feasibility screening
“We're shortlisting four candidate plots in Germany and Austria for a hillside development project — can you rank them by maximum slope so we know which will need the most expensive groundwork? Plots: Berchtesgaden (47.63N, 13.00E), Zugspitze foothills (47.42N, 11.00E), Schwarzwald slope (47.93N, 8.13E), and Wachau valley (48.37N, 15.43E).”
Erosion risk ranking for conservation
“I need to prioritize erosion control efforts across seven sites in the Apennines — please rank them by maximum slope so I know where intervention is most urgent. Sites: La Spezia (44.11N, 9.82E), Pistoia (43.93N, 10.91E), Arezzo (43.46N, 11.88E), Perugia (43.11N, 12.39E), Rieti (42.40N, 12.86E), Isernia (41.60N, 14.23E), and Campobasso (41.56N, 14.66E).”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/rank-sites-max-slopeWhen to prefer
Use this endpoint when you need to compare and rank terrain steepness across multiple (2–10) named European sites simultaneously and want a single ranked output with ties preserved, rather than fetching individual slope values and sorting them yourself. Prefer this over the two-site signed-difference sibling endpoint when you have more than two candidate locations and need ordinal ranking rather than a pairwise difference score.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) cause validation errors
- Fewer than 2 or more than 10 locations triggers schema validation failure
- Missing required latitude or longitude for any location returns an error
- Network or upstream DEM data unavailability may cause transient failures
- Malformed location objects with extra properties rejected due to additionalProperties:false
