How this service works
Mean SoilGrids sand fraction for the 0-5 cm layer. The service evaluates the bounded polygon supplied by the caller and returns standardized units across all 30 covered countries.
Output
A standardized mean sand fraction value (likely as a percentage or volumetric fraction) for the 0–5 cm topsoil layer within the supplied polygon, derived from SoilGrids global soil data, covering any of 30 European countries.
Example use cases
Topsoil sand assessment for farm acquisition
“I'm evaluating a farmland plot in northern France before purchase. Can you get me the mean sand fraction in the top 5 cm of soil for this parcel? Polygon vertices are: [[2.31, 48.85], [2.32, 48.85], [2.32, 48.86], [2.31, 48.86]].”
Crop suitability screening in Spain
“We're deciding whether to grow drought-tolerant crops on a plot in Andalusia — can you check the topsoil sand fraction for this polygon: [[-4.42, 37.88], [-4.41, 37.88], [-4.41, 37.89], [-4.42, 37.89]]? Sandy soils drain fast so it matters for our irrigation planning.”
Soil texture data enrichment for land registry
“I'm building a soil quality dataset for parcels in the Netherlands and need the SoilGrids sand fraction for the 0–5 cm layer for this polygon: [[4.90, 52.37], [4.91, 52.37], [4.91, 52.38], [4.90, 52.38]].”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-soil-sand-parcelWhen to prefer
Choose this endpoint when you need parcel-level mean topsoil sand fraction for a custom polygon boundary in Europe, particularly when working with SoilGrids-standardized data across multiple countries. Prefer this over point-based or fixed-radius variants when you have an exact land parcel geometry and need an area-aggregated result rather than a local buffer estimate.
Side effects
- Polygon spans more than 0.25 degrees — request rejected with validation error
- Fewer than 3 coordinate pairs supplied — invalid polygon error
- Coordinates fall outside the 30-country European coverage area — out-of-bounds error
- Polygon self-intersects or is malformed — geometry validation failure
- Payment not attached or insufficient — HTTP 402 payment required
