How this service works
Share of ESA WorldCover 2021 pixels classified as grassland. The service evaluates a circular 1,000 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A standardized numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels classified as grassland within the 1,000-metre circular buffer around the supplied coordinate, consistent across all 30 covered European countries.
Example use cases
Farm site grassland assessment
“I'm evaluating a potential farm site near latitude 51.5, longitude 10.2 in central Germany — can you tell me what percentage of the land within 1 km is grassland based on ESA WorldCover 2021?”
Biodiversity corridor planning
“We're planning a wildlife corridor near latitude 46.2, longitude 6.1 in the Alps foothills — what fraction of the 1-kilometre area around that point is grassland?”
Carbon offset project land audit
“For our carbon sequestration project site at latitude 53.3, longitude -1.5 in northern England, what share of the surrounding 1 km is classified as grassland?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-grassland-share-buffer-1000mWhen to prefer
Use this endpoint when you need a medium-scale (1 km radius) grassland land cover fraction around a single point in Europe, especially when cross-country standardization matters. Prefer this over the 250 m buffer variant when broader neighborhood context is needed, and over the polygon variant when you only have a point coordinate rather than a defined boundary.
Side effects
- Coordinates outside the covered European bounding box (lat 34–72.5, lon -31.5–40.5) will return an error
- Invalid or non-numeric latitude/longitude values cause a validation error
- Payment failure or insufficient USDC balance prevents the call from completing
- Network timeout if the raster computation takes longer than expected
