How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
A numeric value representing the share (proportion or percentage) of ESA WorldCover 2021 pixels classified as built-up within the analysis area centered on the provided Danish coordinate. Coordinates outside Denmark's Natural Earth boundary are rejected before any payment is processed.
Example use cases
Site suitability screening for development
“I'm evaluating a parcel near Aarhus — can you check the built-up land share at latitude 56.162, longitude 10.203 in Denmark so I know how developed the surrounding area already is?”
Urban sprawl monitoring for a Danish municipality
“We're tracking urbanization trends around Odense. Can you look up the ESA WorldCover built-up pixel share at latitude 55.396, longitude 10.388 in Denmark for our report?”
Environmental impact assessment input
“For an ecological impact study I need to know how much of the land around latitude 57.048, longitude 9.921 in Denmark is classified as built-up by satellite data — can you get that figure?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-built-up-shareWhen to prefer
Use this endpoint when you need satellite-derived built-up land cover data specifically for a point location within Denmark, and want ESA WorldCover 2021 classification at low per-call cost. Prefer this over general geospatial APIs when you need Denmark-validated results with boundary enforcement and pay-per-query pricing via x402.
Side effects
- Coordinate outside Denmark's Natural Earth boundary — request rejected without charge
- Coordinate within the broad European bounding box but outside Denmark — rejected at validation
- Malformed latitude/longitude values outside WGS84 range — input validation error
- Coordinate in a maritime or coastal area not covered by the land dataset — may return zero or error
