How this service works
Mean first-order surface gradient across the analysis grid. The service evaluates a circular 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
Returns the mean first-order surface gradient (slope) computed over a 1,000-metre circular neighbourhood centred on the supplied coordinate, expressed in standardized units. Coverage spans 30 European countries within WGS84 latitude 34–72.5° and longitude -31.5–40.5°.
Example use cases
Solar farm site suitability screening
“Can you check the mean terrain slope within 1km of latitude 41.3851, longitude 2.1734 in Spain? I need to know if the land is flat enough for a solar installation.”
Agricultural land assessment
“What's the average slope gradient around latitude 51.5074, longitude -0.1278 in the UK within a 1000-metre radius? I'm evaluating whether this farmland is suitable for mechanised crop harvesting.”
Infrastructure routing pre-check
“I'm planning a road corridor near latitude 48.8566, longitude 2.3522 in France — can you get me the mean surface slope for the 1km area around that point so I know how steep the terrain is?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-mean-slope-buffer-1000mWhen to prefer
Choose this endpoint when you need a spatially averaged slope metric for a 1km radius around a single European coordinate, particularly for site suitability assessments, infrastructure planning, agricultural analysis, or environmental modelling. Prefer it over smaller-radius sibling endpoints (e.g. 60m or 250m buffers) when regional-scale terrain context matters more than hyper-local gradient variation.
Side effects
- Coordinate outside European coverage bounds (latitude not in 34–72.5, longitude not in -31.5–40.5) returns an error
- Invalid or missing latitude/longitude fields return a validation error
- Payment failure or insufficient USDC balance prevents call completion
- Server-side data gap for remote or coastal edge areas may yield null or degraded result
