HALOWERK Atlantic Land – Netherlands Surface Ruggedness (Std Dev of Elevation)
x402
HALOWERK Atlantic Land – Netherlands Surface Ruggedness (Std Dev of Elevation) is a paid API for AI agents from atlantikland.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 index) for a given WGS84 coordinate within the Netherlands boundary.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Netherlands; 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 the Netherlands boundary (as validated against Natural Earth) are rejected before any payment is processed.
Example use cases
Land suitability assessment for development
“I'm evaluating a plot near latitude 51.92, longitude 4.48 in the Netherlands for construction — can you check how rugged or flat the terrain is there by getting the surface elevation standard deviation?”
Agricultural terrain roughness check
“We're planning to farm near latitude 53.21, longitude 6.57 in the Netherlands — can you tell me the standard deviation of surface elevations to understand how uneven the terrain is?”
Flood risk and drainage analysis
“For our drainage project at latitude 52.08, longitude 5.12 in the Netherlands, can you pull the terrain ruggedness value — specifically the surface elevation standard deviation — to help us understand the local topography?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/nl-ruggednessWhen to prefer
Choose this endpoint when you need a precise, per-point terrain ruggedness metric (elevation standard deviation) for a location specifically within the Netherlands. It is ideal for land assessment, construction planning, agricultural analysis, or hydrological studies where topographic roughness at a specific Dutch coordinate is required. The pre-payment boundary validation ensures no charges for out-of-scope coordinates.
Side effects
- Coordinate outside Netherlands Natural Earth boundary — request rejected before payment with a boundary validation error
- Latitude or longitude outside published European coverage range (lat: 34–72.5, lon: -31.5–40.5) — schema validation error
- Invalid coordinate format or missing parameters — input validation failure
- Ambiguous or edge-case boundary coordinates may be rejected even if geographically close to the Netherlands
