How this service works
Share of ESA WorldCover 2021 pixels classified as built-up. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
A numeric value representing the fraction (share) of ESA WorldCover 2021 raster pixels classified as built-up within the analysis area surrounding the given coordinate inside Croatia. The response covers only coordinates validated against the Natural Earth boundary for Croatia; out-of-bounds coordinates are rejected before any charge is applied.
Example use cases
Urban density check for site selection
“We're evaluating a potential logistics hub near Osijek, Croatia — can you tell me the built-up pixel share from ESA WorldCover 2021 at latitude 45.5511, longitude 18.6939? We need to understand how urbanized the surrounding area is.”
Comparing urbanization across Croatian cities
“I want to compare built-up land cover at the centers of Split and Rijeka in Croatia. Can you look up the ESA WorldCover built-up share for Split at 43.5081, 16.4402 and Rijeka at 45.3271, 14.4422?”
Environmental impact assessment
“For an environmental report on a construction project near Dubrovnik, Croatia — around latitude 42.6507, longitude 18.0944 — can you get the share of built-up pixels from the ESA WorldCover 2021 dataset?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-built-up-shareWhen to prefer
Choose this endpoint when you need pixel-level built-up land cover statistics for a specific point in Croatia using the authoritative ESA WorldCover 2021 dataset. It is ideal for urban density analysis, site assessments, environmental reporting, or any geospatial pipeline that requires quantified impervious-surface fractions validated against official Croatian boundaries. It is not suitable for coordinates outside Croatia or for other land cover classes such as tree cover (use the sibling tree-cover endpoint instead).
Side effects
- Coordinate outside Croatia boundary — rejected before payment with a validation error
- Latitude or longitude outside European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed request body or missing required parameters — HTTP 400
- Service unavailability or upstream ESA data access failure — HTTP 500
- Payment failure or insufficient USDC balance — HTTP 402
