HALOWERK Central Land – Surface Ruggedness (Slovenia)
x402
HALOWERK Central Land – Surface Ruggedness (Slovenia) 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 as a terrain ruggedness index for a given WGS84 coordinate within Slovenia.

How this service works
Standard deviation of sampled surface elevations. The coordinate is validated against the Natural Earth boundary for Slovenia; results outside it are rejected before payment.
Output
A numeric value representing the standard deviation of sampled surface elevations within the analysis neighborhood around the given coordinate, indicating terrain ruggedness. Higher values mean more irregular, rough terrain; lower values indicate flatter surfaces. Coordinates outside Slovenia's Natural Earth boundary are rejected before processing.
Example use cases
Agricultural site suitability assessment
“I'm evaluating a potential farmland parcel near Novo Mesto, Slovenia — can you check the terrain ruggedness at latitude 45.80, longitude 15.17 so I know how uneven the surface is?”
Hiking trail difficulty estimation
“For a trail planning project, what is the surface elevation standard deviation at latitude 46.38, longitude 13.84 in the Triglav area of Slovenia?”
Wildlife habitat terrain complexity
“I need the terrain ruggedness index at latitude 46.55, longitude 15.65 in northeastern Slovenia for a habitat suitability model I'm building.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/si-ruggednessWhen to prefer
Choose this endpoint when you need a quantitative ruggedness or terrain roughness metric specifically for locations in Slovenia, based on Copernicus DEM GLO-30 data. It is ideal for land suitability analysis, ecological modeling, infrastructure planning, or any application requiring a standardized elevation variability measure rather than raw elevation or slope. Prefer it over generic elevation APIs when the standard deviation of elevations (ruggedness) rather than mean elevation or gradient is the desired metric, and when your location is confirmed to be within Slovenia.
Side effects
- Coordinate outside Slovenia boundary returns a validation error before any computation
- Latitude or longitude outside the allowed European range (34–72.5°N, -31.5–40.5°E) causes rejection
- Invalid or missing coordinate fields return a schema validation error
- Payment failure via x402 protocol prevents the call from completing
- Network timeout for edge locations or slow DEM tile retrieval
