How this service works
Measures elevation 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 their measured elevation values, with ties preserved in the ranking (equal-elevation sites share the same rank position). Each entry includes the site name, its elevation measurement, and its rank.
Example use cases
Alpine route elevation pre-screening
“I'm planning a cross-Alpine trip and want to rank these six waypoints by elevation: Chamonix (45.9237°N, 6.8694°E), Courmayeur (45.7968°N, 7.0371°E), Zermatt (46.0207°N, 7.7491°E), Grindelwald (46.6243°N, 8.0410°E), Davos (46.8027°N, 9.8370°E), and Innsbruck (47.2692°N, 11.4041°E). Rank them highest to lowest.”
Renewable energy site elevation comparison
“We're evaluating wind farm sites across Europe — can you rank these seven candidate locations by elevation so we can prioritize the highest-altitude ones? Coordinates are: 41.6°N 1.5°E, 43.3°N 3.2°E, 47.1°N 8.4°E, 50.2°N 14.4°E, 52.5°N 13.4°E, 48.8°N 2.3°E, 46.2°N 6.1°E.”
Multi-city property elevation ranking
“I need to compare elevation for these four European cities for a real estate report: Madrid (40.4168°N, 3.7038°W), Lisbon (38.7169°N, 9.1399°W), Rome (41.9028°N, 12.4964°E), and Athens (37.9838°N, 23.7275°E) — please rank them from lowest to highest and flag any ties.”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/rank-sites-elevationWhen to prefer
Choose this endpoint when you need to compare and rank elevation across multiple (2–10) European sites simultaneously in a single call, preserving ties. Prefer it over single-coordinate elevation lookups when ranking or ordering is the goal, and over generic elevation APIs when the coverage area is specifically European and the tie-aware ranking output format is needed.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5°N, lon -31.5–40.5°E) will be rejected
- Fewer than 2 or more than 10 sites submitted will fail validation
- Missing required latitude or longitude fields cause a schema validation error
- Name field exceeding 60 characters will be rejected
- Elevation data unavailable for extremely remote or ocean coordinates within nominal bounds
