How this service works
Measures terrain ruggedness for two to ten named European sites and ranks the observed values with ties preserved.
Output
Returns a ranked list of the submitted named European sites ordered by terrain ruggedness index, with tied values preserved and explicitly indicated. Each entry includes the site name, its computed ruggedness score, and its rank position.
Example use cases
Hiking trail difficulty comparison
“I'm planning a hiking trip and want to know which of these three locations has the roughest terrain — rank them by ruggedness: Dolomites at 46.4102, 11.8440; Black Forest at 47.9990, 8.2270; and Pyrenees foothills at 42.8591, 0.7144.”
Infrastructure site suitability ranking
“We're evaluating five candidate sites in Europe for a construction project and need to rank them by terrain ruggedness from smoothest to most rugged: Lisbon (38.7169, -9.1395), Madrid (40.4168, -3.7038), Lyon (45.7640, 4.8357), Munich (48.1351, 11.5820), and Warsaw (52.2297, 21.0122).”
Ecological research site selection
“For our ecological field study, rank these four European sites by terrain ruggedness so we can prioritize the most topographically varied ones: Carpathians at 49.0000, 22.0000; Scottish Highlands at 57.1200, -4.7100; Apennines at 44.2700, 10.9200; and Massif Central at 45.3500, 2.9000.”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/rank-sites-ruggednessWhen to prefer
Choose this endpoint when you need to compare and rank terrain ruggedness across multiple European sites simultaneously (2–10) with tie handling included. Prefer it over pairwise comparison endpoints when you have more than two sites to evaluate and need a full ordinal ranking rather than a signed difference. Ideal for site selection, ecological research, infrastructure planning, or outdoor activity planning within Europe.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) return a validation error
- Fewer than 2 or more than 10 locations provided returns a schema error
- Missing required latitude or longitude fields returns a 400 bad request
- Invalid numeric values for coordinates return a parsing error
- Payment not fulfilled (x402) returns a 402 Payment Required response
