How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Romania; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (0–360 degrees, clockwise from north) of the dominant surface gradient at the queried coordinate. Coordinates outside Romania's Natural Earth boundary are rejected before any payment is charged.
Example use cases
Solar panel orientation for Romanian farmland
“I'm planning a solar installation on a hillside near Cluj at latitude 46.77, longitude 23.6 in Romania — can you tell me which direction the terrain faces so I can figure out sun exposure?”
Vineyard site suitability assessment
“I'm evaluating a plot at 44.9 latitude, 26.1 longitude in Romania for planting vines — can you check the terrain aspect so I know whether the slope faces south and gets good afternoon sun?”
Hiking trail wind exposure analysis
“For a trail planning project in the Carpathians at latitude 45.4, longitude 24.8 in Romania, can you find the dominant slope-facing direction so we can assess prevailing wind exposure on that hillside?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/ro-aspectWhen to prefer
Choose this endpoint when you need terrain aspect (slope-facing direction) specifically for coordinates within Romania, and need boundary pre-validation to avoid wasted charges. It is part of a suite of land-surface analytics endpoints from HALOWERK that cover slope, ruggedness, runoff, soil, and land cover — making it ideal when building multi-variable terrain profiles for Romanian locations.
Side effects
- Coordinate outside Romania's Natural Earth boundary — request rejected before payment, no charge incurred
- Latitude or longitude out of the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude field — schema validation failure
- Tile data unavailable for the exact coordinate — possible null or error response
