How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.
Output
A numeric value representing the fraction (share) of ESA WorldCover 2021 pixels within the analysis area around the given coordinate that are classified as built-up land. Coordinates outside the Natural Earth boundary for Poland are rejected before payment is processed.
Example use cases
Urban density check for site selection
“We're evaluating a potential warehouse site in Poland near lat 51.1079, lon 17.0385 — can you tell me what fraction of the surrounding land is classified as built-up according to ESA WorldCover?”
Planning greenfield development in Poland
“I need to know how urbanized the land is around coordinates 50.0647° N, 19.9450° E in Kraków — specifically the built-up land cover share — before we submit a planning proposal.”
Environmental impact baseline for Polish project
“For our impact assessment, can you pull the built-up pixel share from ESA WorldCover 2021 for the location at 54.3520° N, 18.6466° E in Gdańsk?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-built-up-shareWhen to prefer
Choose this endpoint when you need a precise, pixel-level built-up land cover fraction specifically for a point within Poland, sourced from the authoritative ESA WorldCover 2021 dataset. It is ideal for urban analysis, site suitability, environmental assessments, or any workflow that requires impervious/built-up surface quantification for Polish locations. The pre-payment coordinate validation against Poland's Natural Earth boundary ensures you are not charged for out-of-scope requests.
Side effects
- Coordinate outside Poland boundary: request rejected before payment, no charge incurred
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Malformed or missing coordinate fields: schema validation error
- Coordinate inside European range but outside Poland polygon: boundary rejection error
- Network or upstream data service unavailability: server error response
