How this service works
Mean SoilGrids sand fraction for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
Returns the mean sand fraction (as a proportion or percentage) for the 0–5 cm soil depth layer at the requested coordinate, sourced from SoilGrids data. Coordinates outside Croatia's Natural Earth boundary are rejected before payment is processed.
Example use cases
Agricultural land suitability assessment
“I'm evaluating a plot near Osijek, Croatia at 45.56 latitude and 18.69 longitude — what's the sand fraction in the top 5 cm of soil there?”
Environmental site characterization
“Can you get the surface soil sand content for a Croatian wetland site at latitude 45.23, longitude 16.45? I need it for a habitat suitability study.”
Land investment due diligence
“Before purchasing farmland near Split, Croatia at 43.51 latitude and 16.44 longitude, I want to know the topsoil sand fraction — can you look that up?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-soil-sandWhen to prefer
Use this endpoint when you need SoilGrids sand fraction data specifically for a location within Croatia and require coordinate validation against an authoritative boundary before incurring costs. Prefer this over generic SoilGrids queries when working with Croatian agricultural, environmental, or land-use applications that need guaranteed geographic scoping.
Side effects
- Coordinate outside Croatia's validated boundary — request rejected before payment with a geographic validation error
- Coordinate within European bounding box but outside Croatia — rejected by Natural Earth boundary check
- Missing or malformed latitude/longitude — returns a validation error
- Coordinates at extreme precision or at boundary edge may trigger edge-case rejection
