How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numeric relative runoff tendency score derived from terrain slope and ruggedness for the queried coordinate. Coordinates outside Hungary's Natural Earth boundary are rejected before any payment is processed. The value indicates how prone the surface at that location is to generating runoff.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a farm plot in Hungary near Győr at latitude 47.685 and longitude 17.635 — can you get the runoff tendency score so I know whether the terrain is likely to drain well or accumulate surface water?”
Flood risk pre-screening for site selection
“We're choosing between two sites for a warehouse in Hungary. Can you check the drainage tendency at latitude 47.1625 and longitude 18.4082 to see if the terrain runoff risk is high before we commission a full survey?”
Environmental baseline for land report
“I need the relative runoff tendency at coordinates 48.1 latitude and 20.8 longitude in Hungary as part of a baseline environmental data report for that parcel.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-drainage-tendencyWhen to prefer
Choose this endpoint when you need a fast, pre-computed runoff tendency score specifically for a point within Hungary, based on slope and terrain ruggedness. It is ideal for land assessment, agricultural planning, or environmental screening workflows where a lightweight numeric index is sufficient and a full hydrological model is not required. The built-in boundary validation means you won't be charged for out-of-region queries.
Side effects
- Coordinate outside Hungary boundary — request rejected before payment, error returned indicating location is out of coverage
- Latitude or longitude outside the declared European bounding box (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing or malformed coordinate fields — schema validation error
- Elevation or terrain data unavailable for the exact grid cell — may return null or partial result
