## When to prefer this

Choose this endpoint when you need the official ESA WorldCover 2021 dominant land cover classification for a point in Iceland or Europe and require boundary validation to ensure the coordinate is geographically valid. Prefer it over general geospatial APIs when ESA WorldCover 2021 specifically is required, or when working in Nordic/Icelandic geographies where Natural Earth boundary checking adds reliability.

## Known failure modes

- Coordinate outside Iceland/European Natural Earth boundary — request rejected before payment
- Latitude or longitude out of the accepted range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed coordinate values (non-numeric or null) — input schema validation failure
- Service unavailable or upstream ESA data unreachable — HTTP 5xx error

## How this service works

Dominant ESA WorldCover 2021 class in the analysis area. The coordinate is validated against the Natural Earth boundary for Iceland; results outside it are rejected before payment.

## Output

Returns the dominant ESA WorldCover 2021 land cover class label (e.g. Tree cover, Shrubland, Grassland, Cropland, Built-up, Bare/sparse vegetation, Snow and ice, Permanent water bodies, Herbaceous wetland, Mangroves, Moss and lichen) for the queried coordinate, provided the coordinate falls within the validated Iceland (or European) boundary.
