How this service works
Share of ESA WorldCover 2021 pixels classified as grassland. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels within the analysis grid around the given coordinate that are classified as grassland. Only coordinates validated as lying within the Hungary boundary are accepted; out-of-bounds coordinates are rejected before payment is processed.
Example use cases
Agricultural site suitability assessment
“I'm evaluating a plot near latitude 47.2 and longitude 18.4 in Hungary for livestock grazing — can you tell me what fraction of the surrounding area is classified as grassland by ESA WorldCover 2021?”
Biodiversity habitat mapping
“We're studying grassland habitats in Hungary. Can you get the ESA WorldCover grassland share for the coordinate at lat 46.9, lon 20.1?”
Land use change monitoring
“I need to check the current grassland coverage fraction for our field site at latitude 47.8, longitude 17.6 in Hungary to compare it against historical records.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hu-grassland-shareWhen to prefer
Use this endpoint when you need ESA WorldCover 2021 grassland land cover fraction specifically for points within Hungary. It is the right choice for agricultural suitability analysis, ecological surveys, habitat mapping, or land use studies focused on Hungarian territory. It performs boundary validation before charging, reducing wasted payments for off-target coordinates. Prefer this over general land cover APIs when you need a precise, per-point grassland share derived from a well-known 10 m resolution satellite product.
Side effects
- Coordinate outside Hungary boundary — rejected before payment with a validation error
- Coordinate outside European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing or malformed latitude/longitude — request error
- Service unavailable or upstream ESA WorldCover data issue — server error
