How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
A numeric share (fraction or percentage) of ESA WorldCover 2021 pixels classified as built-up within the analysis area surrounding the given coordinate. Coordinates outside the Natural Earth boundary for Spain are rejected before any charge is applied.
Example use cases
Urban density check for site selection
“I'm evaluating a plot near Madrid at 40.45 latitude, -3.68 longitude — can you tell me what fraction of that area is classified as built-up according to ESA WorldCover 2021?”
Planning permit urbanization context
“For a planning report on a development site in Barcelona at latitude 41.385, longitude 2.173, what percentage of surrounding pixels are classified as built-up land?”
Rural vs urban classification for real estate
“I need to know how urbanized the land is around a property in Seville at 37.392 latitude, -5.994 longitude — specifically the ESA WorldCover built-up share.”

Endpoint
POSThttps://suedland.halowerk.com/v1/es-built-up-shareWhen to prefer
Choose this endpoint when you need the specific ESA WorldCover 2021 built-up land-cover fraction for a point within Spain. It is purpose-built for Spain with boundary validation, making it more reliable than generic global land-cover APIs for Spanish coordinates. It complements the other HALOWERK Southern Land endpoints (grassland share, soil properties, elevation, dominant cover class) for multi-dimensional land analysis in Spain.
Side effects
- Coordinate outside Spain boundary: rejected before payment with a validation error
- Latitude or longitude out of published European coverage range (lat 34–72.5, lon -31.5–40.5): rejected
- Malformed or missing coordinate fields: schema validation error
- Network or service timeout: no result returned
- Payment failure via x402 protocol: request not processed
