Copernicus EMS Rapid Mapping Grading Products

Event- and AOI-specific Rapid Mapping Grading (GRA) products derived from post-event satellite imagery and other geospatial sources. A grading product reports event extent and damage grade/spatial distribution for assets including building points or polygons. Public activation APIs expose event, imagery, AOI, product, version, issue, layer and download metadata; completed public products are downloadable as vector ZIPs and, for current deliveries, GeoPackages. Damage classes are Destroyed, Damaged, Possibly damaged, No visible damage and Not Analysed. `Damaged` aggregates EMS-98 grades 1–3, `Destroyed` aggregates grades 4–5, and `Possibly damaged` records lower interpretation confidence. Results are imagery-based proxies, not field-confirmed ground truth. Availability is limited to produced, non-sensitive activation/AOI products.
