How this service works
Mean SoilGrids silt fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric value representing the mean SoilGrids silt fraction (as a proportion or percentage) for the 0–5 cm topsoil layer at the specified coordinate. Returns an error or rejection if the coordinate falls outside the validated Natural Earth boundary for Portugal.
Example use cases
Agricultural site suitability assessment
“I'm evaluating a farm plot near Évora at latitude 38.57, longitude -7.91 – can you get me the silt fraction of the top 5 cm of soil there so I can assess drainage and tillage suitability?”
Soil texture mapping for environmental study
“For my environmental survey in the Algarve, I need the SoilGrids silt fraction at the 0–5 cm layer for coordinates latitude 37.10, longitude -8.67 in Portugal.”
Land degradation risk modeling
“I'm modeling erosion risk in northern Portugal and need the topsoil silt fraction at latitude 41.55, longitude -8.43 – can you pull that from the soil database?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-soil-siltWhen to prefer
Use this endpoint when you specifically need the silt fraction component of soil texture for a location within Portugal and want data sourced from the globally consistent SoilGrids dataset at the 0–5 cm depth. Prefer it over generic soil APIs when boundary validation against Portugal's Natural Earth polygon is required, or when you need a low-cost per-call lookup without managing raw raster data.
Side effects
- Coordinate outside Portugal boundary: request rejected before payment is processed
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Invalid or missing coordinate fields: schema validation error
- Service unavailable or upstream SoilGrids data not accessible: 5xx error
