How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. 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 share of ESA WorldCover 2021 pixels classified as built-up within a 250-metre circular buffer around the supplied coordinate. Coverage applies to 30 European countries.
Example use cases
Urban density check for site selection
“I'm evaluating a potential retail location at latitude 52.3676, longitude 4.9041 in Amsterdam — can you tell me what fraction of the 250-metre neighbourhood is built-up land?”
Environmental impact report for planning
“For a planning application near latitude 51.5074, longitude -0.1278 in London, I need the share of built-up ESA WorldCover pixels within 250 metres of that point.”
Urbanization level for real estate valuation
“I need to know how urbanized the surroundings are for a property at latitude 48.1351, longitude 11.5820 in Munich — specifically the built-up land cover share within a 250-metre radius.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-built-up-share-buffer-250mWhen to prefer
Choose this endpoint when you need a precise, small-scale (250m radius) measure of built-up land cover at a single European point, sourced from the authoritative ESA WorldCover 2021 dataset. Prefer it over coarser-resolution datasets when local urbanization context matters — e.g. site selection, planning assessments, or property analytics — and when only a single coordinate lookup is needed rather than a polygon area analysis.
Side effects
- Coordinates outside the European bounding box (lat 34–72.5, lon -31.5–40.5) will be rejected
- Missing or malformed latitude/longitude fields return a validation error
- Coordinates over open water or outside WorldCover data extent may return null or zero share
- Payment failure via x402 protocol will prevent the request from completing
