How this service works
Mean first-order surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Luxembourg; results outside it are rejected before payment.
Output
Returns the mean first-order surface gradient (slope value) computed across the analysis grid for the submitted coordinate, applicable only to points within Luxembourg's Natural Earth boundary. Coordinates outside this boundary are rejected before any payment is processed.
Example use cases
Site suitability for Luxembourg construction
“I'm evaluating a potential building site in Luxembourg at 49.75° N, 6.08° E — can you get me the mean terrain slope there so I know if the gradient is suitable for construction?”
Agricultural slope assessment in Luxembourg
“I need the average surface gradient at 49.55° N, 6.35° E in Luxembourg to assess whether the terrain is too steep for mechanized farming.”
Runoff risk pre-screening for Luxembourg parcel
“Can you look up the mean slope for the location at 49.82° N, 5.97° E in Luxembourg? I want to understand the terrain gradient before estimating runoff risk for that parcel.”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/lu-mean-slopeWhen to prefer
Choose this endpoint when you specifically need mean surface slope data for a point coordinate within Luxembourg. It is purpose-built for Luxembourg territory analysis with boundary validation before billing, making it cost-safe for exploratory calls. Prefer it over generic elevation or DEM APIs when you need a pre-aggregated gradient value rather than raw elevation, and when your use case is scoped to Luxembourg.
Side effects
- Coordinate outside Luxembourg's Natural Earth boundary — request rejected before payment, returns boundary validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Malformed request body or missing required fields — returns input validation error
- Service unavailable or timeout — returns server error
