How this service works
South-facing slope orientation index derived from aspect and slope. The coordinate is validated against the Natural Earth boundary for Bulgaria; results outside it are rejected before payment.
Output
A numeric south-facing slope orientation index derived from terrain aspect and slope data at the queried coordinate. Coordinates outside the Natural Earth boundary for Bulgaria are rejected before any computation or payment is charged.
Example use cases
Solar farm site scouting in Bulgaria
“We're evaluating a hillside plot near Plovdiv at lat 42.08, lon 24.62 — can you get the south-facing slope orientation index to see if it's well-positioned for a solar installation?”
Agricultural land solar suitability check
“I have a vineyard parcel in Bulgaria at latitude 41.95, longitude 25.10. Can you pull the solar orientation index so I know how much south-facing sun exposure the slope gets?”
Terrain analysis for eco-housing project
“For our passive solar house project near Veliko Tarnovo, can you check the slope orientation index at coordinates 42.88 latitude, 25.37 longitude to confirm it's south-facing enough?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-solar-orientationWhen to prefer
Choose this endpoint when you need a terrain-derived solar orientation metric specifically for coordinates within Bulgaria. It is purpose-built for Bulgaria with built-in boundary validation, making it more reliable than general-purpose elevation or aspect APIs for Bulgarian land parcels. Prefer it for solar energy siting, agricultural planning, or passive solar architecture assessments in Bulgaria.
Side effects
- Coordinate outside Bulgaria boundary — request rejected before payment with a boundary validation error
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Invalid input types for latitude or longitude — request rejected with a type/schema error
- Network timeout or service unavailability — HTTP 5xx response
