How this service works
Mean first-order surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
A numeric value representing the mean first-order surface gradient (slope) computed across the analysis grid for the specified coordinate. The coordinate is validated against the Natural Earth boundary for Denmark; requests outside Denmark are rejected before payment is processed.
Example use cases
Solar farm site suitability check
“I'm evaluating a site near Vejle, Denmark — can you get me the mean terrain slope at latitude 55.71, longitude 9.54? I need to know how steep the ground is before we proceed with the solar panel layout.”
Agricultural land drainage planning
“We're planning drainage works on a Danish field at latitude 56.20, longitude 10.05 — what's the average surface gradient there so we can figure out natural runoff direction?”
Construction feasibility terrain analysis
“Can you check the mean slope at latitude 55.40, longitude 11.75 in Denmark for our engineering team? They need the terrain steepness value to assess whether the site is suitable for foundation work.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-mean-slopeWhen to prefer
Use this endpoint when you need a precise mean terrain slope value for a specific coordinate within Denmark. It is ideal for site suitability assessments, agricultural planning, construction feasibility studies, or any geospatial analysis requiring terrain gradient data at a Danish location. It is distinct from sibling endpoints that return soil properties, land cover, or elevation statistics.
Side effects
- Coordinate outside Denmark boundary — rejected before payment with a boundary validation error
- Latitude or longitude outside the published European coverage range — schema validation error
- Malformed or missing coordinate fields — request rejected with input validation error
- Temporary service unavailability — HTTP 5xx error returned
