HALOWERK Baltic Land – Latvia Aspect (Surface Gradient Direction)
x402
HALOWERK Baltic Land – Latvia Aspect (Surface Gradient Direction) is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).
Returns the circular direction of the dominant surface gradient (aspect, clockwise from north) for a given coordinate within Latvia.

How this service works
Circular direction of the dominant surface gradient, clockwise from north. The coordinate is validated against the Natural Earth boundary for Latvia; results outside it are rejected before payment.
Output
A numeric value representing the circular direction (in degrees, clockwise from north, 0–360) of the dominant surface gradient at the queried coordinate. Coordinates outside the Latvia boundary are rejected before payment is processed.
Example use cases
Solar panel site suitability in Latvia
“I'm evaluating a site for solar panels near Sigulda, Latvia — can you tell me which direction the slope faces at latitude 57.15, longitude 24.85? I need the terrain aspect in degrees from north.”
Agricultural field orientation analysis
“For a field at latitude 56.67, longitude 23.72 in Latvia, what direction does the dominant surface gradient face? I want to understand the slope aspect for drainage planning.”
Hiking trail terrain characterization
“We're mapping a hiking trail in the Gauja National Park area — what's the aspect of the hillside at coordinates latitude 57.18, longitude 25.02 in Latvia?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/lv-aspectWhen to prefer
Use this endpoint when you need terrain aspect (slope-facing direction) specifically for locations within Latvia, and you require coordinate validation against the Latvian boundary before incurring cost. Prefer it over generic global elevation/aspect APIs when working with Baltic-region land analysis pipelines, especially when paired with sibling HALOWERK Baltic endpoints for soil, land cover, or topographic metrics.
Side effects
- Coordinate outside Latvia's Natural Earth boundary — request rejected before payment
- Coordinate outside the European coverage bounding box (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing latitude/longitude values — schema validation failure
- Service unavailable or upstream elevation data unreachable — HTTP 5xx error
