HALOWERK Nordic Land – Surface Ruggedness Index (Sweden)
x402
HALOWERK Nordic Land – Surface Ruggedness Index (Sweden) is a paid API for AI agents from nordland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the standard deviation of sampled surface elevations (terrain ruggedness) for a given WGS84 coordinate validated within Sweden's boundaries.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations at the queried coordinate, indicating terrain ruggedness. Coordinates outside Sweden's Natural Earth boundary are rejected before any computation or payment is processed.
Example use cases
Wind turbine site terrain assessment
“I'm evaluating a potential wind turbine location in Sweden at latitude 57.8, longitude 15.1 — can you tell me how rugged the terrain is there so I know whether it's suitable for construction?”
Hiking route difficulty analysis
“I'm planning a hiking trail near latitude 67.9, longitude 18.5 in northern Sweden — can you check the terrain ruggedness score at that coordinate so I can gauge how challenging the terrain will be?”
Wildlife habitat corridor planning
“For a wildlife corridor study in Sweden, I need the surface elevation standard deviation at latitude 60.4, longitude 16.2 — can you pull the terrain ruggedness value for that point?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-ruggednessWhen to prefer
Choose this endpoint when you need a terrain ruggedness metric (elevation standard deviation) specifically for locations within Sweden. It is pre-validated against Sweden's boundary, so you avoid paying for out-of-bounds queries. Prefer this over generic elevation APIs when you need a ruggedness statistic rather than a raw elevation value, or when working in a Nordic/Scandinavian geospatial context.
Side effects
- Coordinate outside Sweden's Natural Earth boundary — request rejected before payment with a validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Network timeout or service unavailability
- Malformed input (non-numeric or missing coordinates)
