How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for Bulgaria; results outside it are rejected before payment.
Output
A numeric relative runoff tendency value derived from slope gradient and terrain ruggedness at the specified coordinate. The coordinate must fall within Bulgaria's Natural Earth boundary; requests outside this area are rejected before billing.
Example use cases
Agricultural site drainage risk screening
“I'm evaluating a farming plot near Plovdiv — can you check the runoff tendency at latitude 42.13, longitude 24.72 so I know if the slope will cause drainage issues for crops?”
Reforestation suitability assessment
“We're planning a reforestation effort and need to assess drainage conditions. What's the drainage tendency score at latitude 43.01, longitude 25.60 in Bulgaria?”
Infrastructure slope hazard evaluation
“Before we approve a road construction route, I need the runoff tendency value at latitude 41.88, longitude 23.45 in Bulgaria to flag any erosion or drainage risks.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-drainage-tendencyWhen to prefer
Use this endpoint when you need a terrain-derived runoff or drainage tendency score specifically for a coordinate in Bulgaria, derived from slope and ruggedness data. Prefer this over general elevation or soil endpoints when the primary concern is hydrological surface-flow tendency rather than raw elevation statistics or soil composition.
Side effects
- Coordinate outside Bulgaria boundary — request is rejected before payment with a validation error
- Latitude or longitude out of the accepted European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid or missing coordinate values — input schema validation failure
- Service unavailability or upstream terrain data error — 5xx response
