How this service works
Share of ESA WorldCover 2021 pixels classified as grassland. The service evaluates a circular 250 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 a 250-metre circular buffer centred on the supplied WGS84 coordinate, consistent across all 30 covered European countries.
Example use cases
Farm suitability assessment for grazing
“I'm evaluating a potential grazing site near latitude 47.8, longitude 13.2 in Austria — can you tell me what fraction of the land within 250 metres is grassland according to ESA WorldCover 2021?”
Ecological corridor mapping
“For a nature connectivity project, I need the grassland share in a 250-metre buffer around coordinates 52.3 latitude, 4.9 longitude in the Netherlands. Can you pull that from ESA WorldCover?”
Environmental impact baseline reporting
“We're doing a baseline land cover assessment near latitude 43.6, longitude 1.4 in France — what percentage of the 250-metre neighbourhood around that point is classified as grassland?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-grassland-share-buffer-250mWhen to prefer
Choose this endpoint when you need a standardized, point-specific grassland fraction for a 250-metre neighbourhood in Europe, particularly for agricultural assessments, ecological studies, or environmental baseline reporting across any of the 30 covered European countries. Prefer it over the 60m or 1,000m buffer variants when you need a neighbourhood-scale (rather than local or landscape-scale) measure of grassland cover.
Side effects
- Coordinate outside covered European bounding box (lat 34–72.5, lon -31.5–40.5) returns an error or empty result
- Missing or malformed latitude/longitude values cause a validation error
- Payment failure via x402 protocol blocks the request
- Server-side processing error if the ESA WorldCover tile is unavailable for the requested area
