HALOWERK Atlantic Land – Netherlands Terrain Aspect (Dominant Gradient Direction)
x402
HALOWERK Atlantic Land – Netherlands Terrain Aspect (Dominant Gradient Direction) is a paid API for AI agents from atlantikland.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Returns the circular direction of the dominant surface gradient (aspect) in degrees clockwise from north for a given coordinate within the Netherlands.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Netherlands; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, 0–360, clockwise from north) of the dominant surface gradient at the specified coordinate. Coordinates outside the Netherlands boundary are rejected before any charge is applied.
Example use cases
Solar panel site suitability screening
“For the land parcel at 51.98°N, 5.42°E in the Netherlands, what direction does the terrain face? I need the aspect angle clockwise from north to assess whether it's south-facing enough for solar panels.”
Agricultural drainage planning
“I'm planning drainage for a field at 52.10°N, 4.65°E in the Netherlands — can you tell me the dominant slope direction in degrees clockwise from north so I know which way water will naturally flow?”
Hiking trail aspect analysis
“What's the terrain aspect at coordinates 53.12°N, 6.57°E in the Netherlands? I want to know which compass direction the slope faces for a trail planning project.”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/nl-aspectWhen to prefer
Choose this endpoint when you need precise terrain aspect (slope-facing direction) data specifically within the Netherlands, especially when pre-payment boundary validation is important. Prefer it over general-purpose DEM APIs when you want a lightweight, per-coordinate micro-call with cost control (only $0.003/call) and Netherlands-specific geographic validation built in.
Side effects
- Coordinate outside Netherlands boundary: rejected before payment, returns validation error
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5): rejected with parameter error
- Missing required latitude or longitude: request returns 400-level error
- Flat terrain with no dominant gradient may return undefined or 0-degree aspect
- Network or service timeout: retry recommended
