How this service works
Mean first-order surface gradient across the analysis grid. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the mean first-order surface gradient (slope) across the analysis grid cell covering the requested Romanian coordinate. Coordinates outside Romania's Natural Earth boundary are rejected before any charge is applied.
Example use cases
Agricultural suitability assessment in Romania
“I'm evaluating farmland near Sibiu — can you check the mean terrain slope at latitude 45.8, longitude 24.15 in Romania? I need to know if it's suitable for mechanized farming.”
Renewable energy site screening
“We're scouting solar panel locations in Romania. What's the average surface slope at latitude 44.5, longitude 26.1? Flat terrain is ideal for our installations.”
Flood risk and runoff modeling
“For a hydrology study near Cluj, can you pull the mean slope value for latitude 46.77, longitude 23.6 in Romania? I need it to estimate water runoff tendency.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/ro-mean-slopeWhen to prefer
Use this endpoint when you need mean terrain slope specifically for locations within Romania and require boundary-validated, pay-per-call geospatial data. Prefer it over generic elevation APIs when you need the average first-order gradient (not max or directional slope) and when Romania-specific validation is important for data quality assurance.
Side effects
- Coordinate outside Romania boundary – request rejected with a geographic validation error before payment
- Coordinate within European coverage range but outside Romania – rejected by Natural Earth boundary check
- Missing or malformed latitude/longitude – returns a schema validation error
- Coordinate at edge of coverage grid with insufficient surrounding data – may return null or an error
