How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Slovakia; results outside it are rejected before payment.
Output
A numeric share (fraction or percentage) representing the proportion of ESA WorldCover 2021 raster pixels within the analysis neighborhood classified as built-up (impervious/urban), for the validated coordinate inside Slovakia.
Example use cases
Urban density check for site selection
“I'm evaluating a potential warehouse site in Slovakia near coordinates 48.72 latitude, 21.26 longitude — can you tell me what fraction of the surrounding land is classified as built-up according to ESA WorldCover 2021?”
Property development risk screening
“Before we proceed with this Slovak land parcel at 49.0 latitude, 18.5 longitude, I need to know what percentage of the area is already built-up so we can assess infill versus greenfield risk.”
Environmental impact baseline for urban sprawl study
“For our urban sprawl analysis in the Bratislava metro area, can you pull the built-up land share from WorldCover 2021 for the point at 48.15 latitude, 17.10 longitude in Slovakia?”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/sk-built-up-shareWhen to prefer
Use this endpoint when you need ESA WorldCover 2021–derived built-up land share specifically for a point within Slovakia, with built-in boundary validation ensuring the coordinate is inside the country before any charge is incurred. Prefer it over generic land-cover APIs when you need satellite-derived impervious surface fractions with per-call micropayment pricing and guaranteed Slovak territorial scope.
Side effects
- Coordinate outside Slovakia boundary rejected before payment — returns an error indicating the point failed the Natural Earth Slovakia boundary check
- Coordinate outside the broader European coverage range (lat 34–72.5, lon -31.5–40.5) returns a validation error
- Malformed or missing latitude/longitude fields return a schema validation error
- Service unavailable or upstream WorldCover data access failure returns a 5xx error
