zonal-coverage
Per-zone coverage fraction from an indexed raster (Canopy Cover and kin) — a web view of GET /api/processes/zonal-coverage.
For every zone of a raster-indexed collection at one level, the fraction of its pixels satisfying a predicate on one band — canopy >= a threshold, land-use class membership, flood-depth exceedance. Computed entirely from the stored zone-mask artifact written at index time: nothing re-fetched, re-projected or resampled. Zones are bucketed by fraction into zoneSets (the overlay-count idiom: identity carries the answer), with an exact per-zone fraction JSON artifact alongside.
