How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.
Output
A numeric value representing the circular direction of the dominant surface gradient in degrees clockwise from north (0–360°) for the queried Finnish coordinate. Coordinates outside Finland's Natural Earth boundary are rejected before any charge is made.
Example use cases
Solar panel site suitability in Finland
“I'm evaluating a site at 60.17° N, 24.94° E in Finland for solar panel installation — can you tell me which direction the terrain faces so I can judge sun exposure?”
Ski slope orientation assessment
“For a potential ski resort development at latitude 68.2, longitude 27.4 in Finland, what direction does the dominant surface slope face? I need the aspect in degrees clockwise from north.”
Forestry terrain characterization
“I'm mapping terrain conditions for a forestry project in Finland. Can you give me the surface aspect at 65.0 latitude, 26.5 longitude?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/fi-aspectWhen to prefer
Use this endpoint when you need terrain aspect (slope-facing direction) specifically for coordinates within Finland. It is ideal when you need precise, validated geospatial terrain data for Finnish locations without risk of paying for out-of-boundary queries. Prefer it over general-purpose DEM services when Finland-specific boundary validation and micropayment-per-call pricing are acceptable.
Side effects
- Coordinate outside Finland boundary: rejected before payment, returns validation error
- Coordinate within Europe but outside Finland: boundary check fails, no result returned
- Malformed or out-of-range latitude/longitude values: schema validation error
- Network or service unavailability: HTTP error response
