How this service works
Share of ESA WorldCover 2021 pixels classified as tree cover. The service evaluates the bounded polygon supplied by the caller and returns standardized units across all 30 covered countries.
Output
A standardized numeric value representing the fraction (or percentage) of ESA WorldCover 2021 pixels within the submitted polygon that are classified as tree cover, consistent across all 30 covered European countries.
Example use cases
Forest cover check for land acquisition
“We're considering buying this plot in Bavaria — the corners are [11.5,48.1],[11.55,48.1],[11.55,48.15],[11.5,48.15]. Can you tell me what fraction of it is classified as tree cover according to ESA WorldCover?”
Afforestation baseline assessment
“I need to establish a tree cover baseline for this reforestation project in northern Spain. The site polygon is [−3.2,42.0],[−3.15,42.0],[−3.15,42.05],[−3.2,42.05] — what percentage is currently classified as trees?”
Environmental due diligence for EU subsidy application
“For our EUDR compliance report, I need the tree cover share for the parcel defined by [5.1,50.5],[5.16,50.5],[5.16,50.55],[5.1,50.55] in Belgium. Can you pull that from the WorldCover data?”

Endpoint
POSThttps://euroland.halowerk.com/v1/europe-tree-cover-share-parcelWhen to prefer
Choose this endpoint when you need ESA WorldCover 2021 tree cover fraction for an arbitrarily shaped land parcel (polygon) in Europe, especially for land due diligence, environmental reporting, or subsidy compliance where exact parcel boundaries matter. Prefer the circular-buffer sibling endpoints if you only have a center point and radius rather than a polygon.
Side effects
- Polygon spans more than 0.25 degrees — request rejected
- Polygon coordinates fall outside the supported European bounding box (longitude −31.5 to 40.5, latitude 34 to 72.5)
- Polygon has fewer than 3 vertices or more than 100 vertices
- Coordinates are malformed or not valid WGS84 values
- Payment failure via x402 protocol prevents execution
