How this service works
Standard deviation of sampled surface elevations. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A numeric value representing the standard deviation of sampled surface elevations within a 250-metre circular neighborhood around the supplied coordinate, expressed in standardized units and covering 30 European countries.
Example use cases
Site suitability for renewable energy
“I'm evaluating a wind farm site in northern Spain — can you tell me how rugged the terrain is within 250 metres of latitude 41.65, longitude -4.72? I need the elevation standard deviation.”
Flood risk terrain screening
“We're assessing flood risk for a location in the Netherlands at latitude 52.09, longitude 5.12 — can you check the terrain ruggedness index using the 250 m buffer elevation data?”
Agricultural land assessment
“Can you check how variable the terrain is around latitude 50.06, longitude 19.94 in Poland? We need the surface elevation standard deviation within 250 metres for a precision farming study.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-ruggedness-buffer-250mWhen to prefer
Choose this endpoint when you need a fast, point-based terrain ruggedness metric for any location across Europe and the 250-metre neighborhood scale is appropriate — ideal for local site assessments, infrastructure siting, and ecological characterization where hyper-local topographic variability matters more than broad landscape-level slope.
Side effects
- Coordinates outside European coverage bounds (latitude 34–72.5, longitude −31.5–40.5) will return an error or out-of-bounds response
- Malformed or missing latitude/longitude values cause a validation error
- Payment failure (x402 protocol) results in a 402 response with no data returned
- Coordinates over open ocean or non-covered territories may return null or zero values
