x402
HALOWERK Central Land – Terrain Ruggedness Index (Czechia) is a paid API for AI agents from mitteleuropa.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns the standard deviation of sampled surface elevations within a local neighborhood around a coordinate in Czechia, quantifying terrain ruggedness.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Czechia; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of surface elevations (in meters) sampled within a neighborhood around the given coordinate, reflecting local terrain ruggedness. Higher values indicate more rugged, hilly terrain; lower values indicate flat terrain. The coordinate must fall within the Czech Republic boundary or the request is rejected.
Example use cases
Site suitability assessment for renewable energy
“I'm evaluating a wind farm site in Czechia near latitude 50.6, longitude 15.1 — can you get the terrain ruggedness score there so I know how variable the surface elevation is?”
Hiking trail difficulty estimation
“I'm planning a hiking route through the Šumava region around lat 49.05, lon 13.45 — what's the terrain ruggedness at that point so I can estimate how tough the terrain will be?”
Agricultural land flatness screening
“We're screening farmland parcels in South Moravia — check the elevation standard deviation at latitude 48.9, longitude 16.6 to see how flat that area is.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-ruggednessWhen to prefer
Choose this endpoint when you specifically need terrain ruggedness (elevation variability / standard deviation of elevations) for a point within Czechia. It is distinct from mean slope endpoints (which return gradient) and convexity endpoints (which return the difference between neighborhood mean and center elevation). Use it for land suitability analysis, ecological assessments, or route planning where surface irregularity matters most.
Side effects
- Coordinate outside Czechia boundary: request rejected before payment with a validation error
- Latitude or longitude out of European coverage range (34–72.5°N, -31.5–40.5°E): rejected with schema validation error
- Invalid or missing coordinate fields: returns a 400-level error
- Temporary backend unavailability: may return 5xx error
