How this service works
Circular direction of the dominant surface gradient, clockwise from north. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.
Output
Returns a standardized numeric value representing the circular direction of the dominant surface gradient in degrees clockwise from north (0–360°), computed over a 60-metre circular analysis grid centred on the supplied coordinate. Coverage spans 30 European countries within the bounds latitude 34–72.5°N, longitude 31.5°W–40.5°E.
Example use cases
Solar panel site suitability screening
“I'm evaluating a site in southern France at latitude 43.72, longitude 5.44 for solar panels — can you tell me which direction the slope faces in degrees from north so I know if it gets good sun exposure?”
Agricultural microclimate assessment
“For a vineyard plot in Burgundy at latitude 47.06, longitude 4.85, what is the terrain aspect — i.e. the clockwise bearing of the slope from north? I need it to assess frost risk and sun exposure.”
Hiking trail terrain characterization
“I'm building a trail database and need the slope aspect at latitude 47.52, longitude 12.88 in the Austrian Alps — give me the dominant surface gradient direction in degrees clockwise from north.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-aspect-pointWhen to prefer
Choose this endpoint when you need a precise, point-level terrain aspect value for any land location within Europe using a fine 60-metre analysis window. It is ideal for site-specific assessments (solar, agriculture, ecology, construction) where local slope orientation matters and you have a single coordinate. Prefer sibling endpoints for polygon inputs, broader radius analysis, or when other land surface variables (land cover, soil pH, wetness) are needed instead.
Side effects
- Coordinate outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) returns an error or null result
- Coordinate over open sea or non-land area may yield no meaningful aspect value
- Payment failure or insufficient USDC balance blocks the request
- Flat terrain with no dominant gradient may return undefined or a special null-aspect indicator
- Malformed or missing latitude/longitude fields return a validation error
