How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Greece; results outside it are rejected before payment.
Output
A numeric share (fraction or percentage) indicating what proportion of ESA WorldCover 2021 pixels in the analysis area around the submitted coordinate are classified as built-up (urban/impervious surface). The coordinate must fall within the Greece boundary as defined by Natural Earth; requests outside this boundary are rejected before any payment is processed.
Example use cases
Urban density check for Greek property
“I'm evaluating a plot of land near Thessaloniki at 40.6401° N, 22.9444° E — can you tell me what percentage of the surrounding area is classified as built-up by ESA WorldCover 2021?”
Site suitability screening for solar farm
“We're considering a solar installation near Kalamata, Greece at 37.0390° N, 22.1142° E — what fraction of that area is built-up? We want to avoid heavily urbanized spots.”
Urban sprawl monitoring in greater Athens
“Can you look up the built-up land cover share at 37.8755° N, 23.8103° E near the outskirts of Athens? I'm tracking urban sprawl over time and need the current WorldCover 2021 figure.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/gr-built-up-shareWhen to prefer
Use this endpoint when you need pixel-level built-up land cover statistics for a specific point location within Greece, sourced from the authoritative ESA WorldCover 2021 dataset. Prefer it over general-purpose geocoding or land use APIs when you need ESA WorldCover-specific classifications (not OpenStreetMap or Corine land cover) and when your use case is strictly Greece-scoped. It pairs well with sibling endpoints on the same platform for cropland share, grassland share, soil properties, and elevation statistics.
Side effects
- Coordinate outside Greece boundary (Natural Earth polygon) — request rejected before payment, no result returned
- Coordinate within European bounding box but not in Greece (e.g. Turkey, Italy) — boundary validation fails
- Missing or out-of-range latitude/longitude values — schema validation error
- Network or service unavailability — HTTP 5xx error
- Payment failure or insufficient USDC balance — x402 payment error
