How this service works
Mean first-order surface gradient across the analysis grid. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.
Output
A numeric value representing the mean first-order surface slope (gradient) across a 60-metre analysis grid centred on the provided coordinate, expressed in standardized units consistent across all 30 covered European countries.
Example use cases
Solar farm site slope check
“Can you get me the mean surface gradient at latitude 38.7, longitude -9.1 in Portugal? I need to know how steep the terrain is before approving a solar panel installation there.”
Alpine hiking trail steepness
“What's the average slope at latitude 46.5, longitude 7.9 in the Swiss Alps? I want to understand how steep that section of terrain is for a trail difficulty assessment.”
Agricultural land suitability
“Fetch the mean terrain slope at latitude 51.2, longitude 10.4 in central Germany — I need to evaluate whether the gradient is suitable for mechanised farming equipment.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-mean-slope-pointWhen to prefer
Use this endpoint when you need point-level terrain slope data for any location within Europe's 30-country coverage, particularly when a standardized 60-metre local analysis window is appropriate (e.g. site assessments, land planning, routing). Prefer this over global DEM APIs when European consistency and per-country standardization matter, and when sub-100m resolution slope analysis is sufficient.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns an error or no-data response
- Invalid or non-numeric latitude/longitude values cause a validation error
- Coastal or offshore coordinates may fall outside land coverage and return null or error
- Network timeout or service unavailability returns a 5xx error
- Payment failure via x402 protocol prevents request from being processed
