How this service works
South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric south-facing slope orientation index derived from terrain aspect and slope at the submitted coordinate, indicating how strongly the terrain faces south. Coordinates outside the Portugal boundary per Natural Earth are rejected before any charge is applied.
Example use cases
Vineyard site solar suitability check
“I'm looking at a potential vineyard site in Portugal at 41.3 latitude, -8.2 longitude — can you calculate the south-facing slope orientation index so I know how well it's exposed to the sun?”
Rooftop solar pre-screening for Portuguese land
“Before I commission a full survey, can you give me the south-facing slope index for coordinates 37.85 latitude, -8.60 longitude in Portugal to see if it's worth installing solar panels there?”
Passive solar building orientation assessment
“I'm designing a house in the Alentejo region at latitude 38.10, longitude -7.90 — what's the south-facing slope orientation score so my architect can plan for passive solar heating?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-solar-orientationWhen to prefer
Use this endpoint when you need a Portugal-specific south-facing slope orientation index derived from aspect and slope data for a precise coordinate, particularly for solar energy siting, agricultural land selection, vineyard planning, or passive solar architecture within Portugal. It validates coordinates against the Natural Earth Portugal boundary before charging, making it safe for automated screening workflows.
Side effects
- Coordinate outside Portugal boundary (Natural Earth) — request rejected before payment, error returned
- Latitude or longitude out of published European coverage range (34–72.5°N, -31.5–40.5°E) — validation error
- Malformed input JSON — schema validation error
- Service unavailability — HTTP 5xx error
