How this service works
Share of ESA WorldCover 2021 pixels classified as cropland. The service evaluates the bounded polygon supplied by the caller and returns standardized units across all 30 covered countries.
Output
A standardized numeric value (fraction or percentage) representing the share of ESA WorldCover 2021 pixels within the supplied polygon that are classified as cropland, consistent across all 30 covered European countries.
Example use cases
Farm parcel cropland eligibility check
“I need to know what percentage of this French farm parcel is cropland — the boundary coordinates are [[2.1, 47.8], [2.1, 47.82], [2.12, 47.82], [2.12, 47.8]]. Can you run it against the ESA WorldCover data?”
Land acquisition due diligence in Poland
“We're considering buying a plot in Poland near Poznań — coordinates [[16.9, 52.4], [16.9, 52.42], [16.92, 52.42], [16.92, 52.4]]. What share of it is classified as cropland by ESA WorldCover 2021?”
Agricultural subsidy compliance verification
“For this parcel in Spain with corners at [[-3.7, 40.4], [-3.7, 40.42], [-3.68, 40.42], [-3.68, 40.4]], what fraction is ESA WorldCover cropland? I need it to verify eligibility for an agricultural subsidy.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-cropland-share-parcelWhen to prefer
Choose this endpoint when you need cropland land-cover fraction for an arbitrary user-defined polygon boundary (parcel, field, or custom area) in Europe, rather than a fixed circular buffer. Use it for due diligence, compliance checks, or site analysis where exact parcel geometry matters. Prefer sibling circular-buffer endpoints when only a radius from a point is available.
Side effects
- Polygon spans more than 0.25 degrees — request rejected with validation error
- Polygon has fewer than 3 coordinate pairs — invalid geometry error
- Coordinates fall outside the covered European bounding box (lat 34–72.5, lon -31.5–40.5) — out-of-coverage error
- Malformed coordinate array or wrong nesting — schema validation failure
- Payment not provided or insufficient — HTTP 402 response
