How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Belgium; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, 0–360, clockwise from north) of the dominant surface gradient at the queried coordinate within Belgium. Coordinates outside the Belgium boundary are rejected before payment is charged.
Example use cases
Solar panel orientation site assessment
“I'm evaluating a field in Belgium at latitude 50.62, longitude 5.57 for solar panels. Can you tell me what direction the slope faces there — the aspect angle clockwise from north?”
Agricultural drainage planning
“For our farm parcel near Ghent at coordinates 51.05 latitude, 3.72 longitude, what is the dominant surface slope direction? I need the aspect bearing to plan field drainage.”
Hiking trail terrain characterization
“I'm mapping a trail section in the Ardennes at 50.15 latitude, 5.82 longitude in Belgium. What's the aspect — the clockwise slope-facing direction from north — at that point?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/be-aspectWhen to prefer
Use this endpoint when you specifically need the dominant surface slope direction (aspect) for a point location within Belgium, particularly for use cases like solar orientation assessment, agricultural planning, hydrological modeling, or ecological habitat analysis. Prefer this over general-purpose GIS APIs when you need a pre-validated, pay-per-call result scoped to Belgium with no infrastructure overhead.
Side effects
- Coordinate outside Belgium boundary — rejected before payment, likely a 422 or 400 error
- Latitude or longitude out of published European coverage range (34–72.5 N, -31.5–40.5 E) — schema validation error
- Missing required latitude or longitude parameter — 400 bad request
- Flat terrain with no discernible aspect direction — may return null or a defined no-data value
- Network or service unavailability — 5xx error
