How this service works
Share of ESA WorldCover 2021 pixels classified as grassland. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as grassland within the analysis area centered on the provided coordinate. The coordinate must fall within the Croatian boundary as validated against Natural Earth; requests outside this boundary are rejected before any payment is charged.
Example use cases
Agricultural land suitability screening
“I'm evaluating a parcel near Osijek, Croatia — coordinates 45.55°N, 18.69°E. What fraction of the surrounding area is classified as grassland in ESA WorldCover 2021?”
Ecological corridor mapping
“For a nature corridor study in central Croatia, can you pull the grassland pixel share at 45.1°N, 16.8°E?”
Carbon credit land baseline
“I need to establish a land cover baseline for a site at 44.8°N, 15.9°E in Croatia — specifically the grassland share from ESA WorldCover 2021 data.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-grassland-shareWhen to prefer
Choose this endpoint when you need a satellite-derived, pixel-level grassland land cover fraction specifically for a coordinate within Croatia. It is ideal for land suitability analysis, ecological assessments, agricultural surveys, or carbon baseline studies where ESA WorldCover 2021 classification is the required data source. Prefer it over generic land cover APIs when Croatian boundary validation and per-call micropayment pricing are acceptable.
Side effects
- Coordinate outside Croatia boundary – rejected before payment with a validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) – schema validation failure
- Malformed request body – missing latitude or longitude fields returns a 400-level error
- Service unavailability – upstream ESA WorldCover data layer temporarily unreachable
