How this service works
Measures local relief for two to ten named European sites and ranks the observed values with ties preserved.
Output
Returns each named site with its measured local relief value and an ordinal rank (1 = highest relief), with tied values assigned identical ranks and subsequent ranks adjusted accordingly.
Example use cases
Site selection for infrastructure project
“I'm evaluating six candidate sites across Europe for a wind farm and need to know which has the most rugged local terrain — can you rank Budapest (47.4979, 19.0402), Lisbon (38.7169, -9.1399), Edinburgh (55.9533, -3.1883), Vienna (48.2082, 16.3738), Seville (37.3891, -5.9845), and Riga (56.9496, 24.1052) by local relief?”
Real estate terrain comparison
“We're comparing three rural European properties and want to know which has the highest and lowest local relief — can you rank Graz (47.0707, 15.4395), Montpellier (43.6108, 3.8767), and Gdańsk (54.3520, 18.6466) by terrain ruggedness?”
Outdoor activity route planning
“I'm planning hiking routes across four regions and need to rank them by terrain roughness — please measure and rank local relief for Innsbruck (47.2692, 11.4041), Reykjavik (64.1355, -21.8954), Chamonix (45.9237, 6.8694), and Trondheim (63.4305, 10.3951).”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/rank-sites-local-reliefWhen to prefer
Use this endpoint when you need to compare local terrain relief across multiple (2–10) European sites simultaneously and want a ranked output with ties preserved. It is preferable over the two-site pairwise endpoints when you have more than two candidates, and preferable over general geospatial APIs when you specifically need local relief as the ranking metric within European coverage.
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 cause schema validation failure
- Missing required latitude or longitude fields trigger a 400 error
- Names exceeding 60 characters are rejected
- Network or upstream terrain data unavailability may return a 5xx error
