How this service works
Share of ESA WorldCover 2021 pixels classified as grassland. The coordinate is validated against the Natural Earth boundary for Portugal; results outside it are rejected before payment.
Output
A numeric value representing the share (fraction or percentage) of ESA WorldCover 2021 pixels in the analysis area classified as grassland for the queried coordinate within Portugal.
Example use cases
Agricultural land assessment in Portugal
“Can you check what fraction of land cover around latitude 37.5, longitude -8.3 in Portugal is grassland? I'm evaluating a potential farm site.”
Ecological habitat screening
“I'm mapping wildlife corridors in Portugal — what's the ESA WorldCover grassland share at coordinates 40.2 latitude, -7.5 longitude?”
Land use monitoring for carbon projects
“For our carbon offset project site at 39.1 latitude, -8.7 longitude in Portugal, what percentage of the surrounding area is classified as grassland by ESA WorldCover 2021?”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/pt-grassland-shareWhen to prefer
Use this endpoint when you specifically need the ESA WorldCover 2021 grassland pixel share for a point location within Portugal. It is best suited for land cover analysis, agricultural assessments, ecological surveys, and carbon project screening within Portuguese territory. Prefer this over general land cover endpoints when you need the grassland class specifically, or over broader European coverage endpoints when your coordinate is confirmed to be in Portugal.
Side effects
- Coordinate outside Portugal boundary — rejected before payment with a validation error
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Malformed or missing input fields — 400-level error
- Network or service timeout — no result returned
- Coordinate in Portugal but over sea or non-land area — may return zero or error
