zonal-statistics
Per-zone statistics over a raster-indexed collection (canopy cover is the canonical case) — a web view of GET /api/processes/zonal-statistics.
Aggregate a raster collection's pixels per zone, straight from the stored zone-mask artifact — pixels were resolved to zones at index time, so this is pure per-zone aggregation; nothing is reprojected or resampled. Statistics: mean, sum, count, min, max, or fraction (of pixels >= threshold — canopy cover from a canopy raster). 'classes' turn values back into MEMBERSHIP: one zoneSet per class ('zones with canopy >= 30%'), the form every other analysis process consumes. Values are exported as a JSON-lines artifact of {zone, value, pixels}.
