How this service works
Combined share of permanent water, herbaceous wetland and mangrove classes. 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 (fraction or percentage) representing the combined share of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, or mangrove within a 250-metre circular buffer around the provided coordinate, applicable across 30 covered European countries.
Example use cases
Wetland proximity check for real estate
“I'm looking at a property near Warsaw, Poland — latitude 52.23, longitude 21.01. Can you tell me what fraction of the land within 250 metres is classified as water or wetland?”
Environmental impact site assessment
“We're evaluating a construction site at latitude 51.50, longitude -0.12 in the UK. What percentage of the 250-metre buffer around it is permanent water or herbaceous wetland according to satellite data?”
Biodiversity corridor mapping
“For a rewilding project near the Danube delta at latitude 45.10, longitude 29.60 in Romania, what is the combined share of water, wetland, and mangrove cover within 250 metres of that point?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-water-wetland-share-buffer-250mWhen to prefer
Choose this endpoint when you need a fine-grained, immediate wetland and water fraction score for a single European point at the 250-metre neighbourhood scale — ideal for site-level environmental assessments, property due diligence, or ecological scoring. Prefer this over the 1,000m buffer variant when hyperlocal precision matters, and over the polygon variant when only a point coordinate is available.
Side effects
- Coordinates outside the European coverage bounding box (lat 34–72.5, lon -31.5–40.5) will return a validation error
- Non-numeric or malformed latitude/longitude values will cause a 400 Bad Request
- Points on the edge of coverage may return partial or zero values if the buffer extends outside the covered area
- Temporary service unavailability may return a 5xx error; retry after a short delay
