How this service works
Mean SoilGrids silt fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.
Output
A numeric value representing the mean silt fraction (likely as a percentage or volumetric proportion) in the 0–5 cm soil layer at the specified Icelandic coordinate, sourced from the SoilGrids dataset. Coordinates outside Iceland's Natural Earth boundary are rejected before any payment is processed.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a plot near Selfoss, Iceland — can you get me the silt fraction in the topsoil at latitude 63.93, longitude -20.99 so I can judge drainage and crop suitability?”
Environmental research soil profiling
“For our ecology study near Akureyri, can you look up the SoilGrids silt content for the 0 to 5 cm layer at coordinates 65.68 north, 18.1 west?”
Construction site ground assessment
“We're planning a build near Reykjavik at lat 64.13, lon -21.82 — what's the topsoil silt fraction there according to SoilGrids?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/is-soil-siltWhen to prefer
Use this endpoint when you specifically need the mean silt fraction from the SoilGrids dataset for a point location within Iceland, particularly when building soil texture profiles or combining with sibling endpoints (sand, clay, pH, organic carbon) for a full picture of topsoil composition. Prefer this over general soil APIs when Iceland boundary validation and micropayment-per-call pricing suit your use case.
Side effects
- Coordinate outside Iceland's Natural Earth boundary — request rejected with no charge
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing or malformed latitude/longitude in request body — input schema error
- SoilGrids data unavailable for the specific location — empty or null result
