How this service works
Mean first-order surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A numeric value representing the mean first-order surface slope gradient (steepness) computed across an analysis grid centered on the requested coordinate. Coordinates outside Germany's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Site suitability for solar farm
“Can you check the average terrain slope at latitude 51.3, longitude 12.4 in Germany? I need to know how flat the land is before evaluating it for a solar farm installation.”
Flood risk terrain pre-screening
“What's the mean surface gradient at lat 53.55, lon 9.99 in Germany? I'm doing a flood risk assessment and need to understand the slope of the terrain there.”
Agricultural land characterization
“Get me the mean slope value for the location at latitude 48.13, longitude 11.58 in Germany — I'm building a soil and terrain profile for agricultural planning purposes.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-mean-slopeWhen to prefer
Choose this endpoint when you need a precise mean surface slope metric for a specific point in Germany, particularly for terrain analysis, site assessment, agricultural planning, or environmental modeling workflows. It is especially useful when Germany-specific validation is required and you want to avoid charges for out-of-bounds coordinates.
Side effects
- Coordinate outside Germany boundary: rejected before payment, returns error indicating invalid location
- Coordinate outside European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Missing or malformed latitude/longitude: request validation error
- Service unavailable: HTTP 5xx error
