How this service works
Difference between maximum and minimum sampled surface elevation. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.
Output
A numeric value representing the local relief in standardized units — the difference between the maximum and minimum sampled surface elevation within a 60-metre analysis grid centered on the provided coordinate. Coverage spans 30 European countries within the latitude range 34–72.5°N and longitude range −31.5–40.5°E.
Example use cases
Site suitability assessment for construction
“We're evaluating a plot at 51.5074° N, -0.1278° E in the UK — can you check the local terrain relief within 60 metres to see how flat or uneven the ground is?”
Agricultural land roughness check
“Before recommending this field in Spain at latitude 40.4168, longitude -3.7038 for mechanized farming, can you tell me how much elevation variation there is in the immediate 60-metre area?”
Outdoor route terrain characterization
“I'm planning a trail near latitude 47.3769, longitude 8.5417 in Switzerland — what's the local relief at that point so I know how rugged the terrain is?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-local-relief-pointWhen to prefer
Choose this endpoint when you need a point-level local terrain roughness or relief metric within a 60-metre radius for any location across 30 European countries, particularly for site assessment, land-use analysis, or environmental characterization workflows where elevation variability at fine spatial scale matters.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon −31.5–40.5) return an error
- Missing or malformed latitude/longitude values cause a 400 Bad Request
- Payment not provided or insufficient USDC triggers a 402 Payment Required
- Temporary service unavailability returns a 5xx error
