How this service works
Relative runoff tendency derived from slope and ruggedness. The coordinate is validated against the Natural Earth boundary for France; results outside it are rejected before payment.
Output
A numeric relative runoff tendency value derived from terrain slope and ruggedness, indicating how strongly a location within France favors surface water drainage; coordinates outside the Natural Earth France boundary are rejected before any charge is applied.
Example use cases
Agricultural site drainage assessment
“I'm evaluating a farm plot near Bordeaux at latitude 44.85, longitude -0.57 — can you tell me the relative runoff tendency so I know how much slope-driven drainage risk there is?”
Urban planning terrain risk check
“We're planning a development in the Loire Valley at around 47.39 latitude, 0.69 longitude — what's the terrain's runoff tendency score based on slope and ruggedness?”
Environmental flood risk screening
“Can you pull the drainage tendency index for coordinates 43.60 latitude, 1.44 longitude near Toulouse? I need it to assess surface water runoff risk for an environmental report.”

Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-drainage-tendencyWhen to prefer
Choose this endpoint when you need a terrain-derived runoff or drainage tendency metric specifically for locations within France, particularly when slope and ruggedness are the relevant hydrological signals. It is well-suited for land assessment, agricultural planning, environmental screening, or flood risk workflows where a lightweight per-coordinate score is needed rather than a full hydrological model. The pre-payment boundary validation makes it cost-efficient by rejecting out-of-bounds coordinates before charging.
Side effects
- Coordinate outside France boundary → request rejected before payment, error response indicating invalid location
- Latitude or longitude outside published European coverage range → validation error
- Malformed input JSON or missing required fields → 400-level error
- Service unavailability or upstream terrain data issues → 5xx error
