Building damage classification

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.

Commercial event intelligence product for impactful wildfires and bushfires. ICEYE combines SAR observations, building footprints, auxiliary fire data, machine learning, and expert analysis to deliver event-scoped building-level vector results. The documented damage output locates assessed structures by latitude/longitude points or building footprints and assigns a binary structural-damage classification of destroyed or undamaged. The product also includes an Esri monitoring application using active-fire locations/perimeters, hotspots, building footprints, and populated urban centres. Results are updated during qualifying events; service availability is currently documented for the United States, Australia, and Canada and is not universal event coverage.

Standing catastrophe-intelligence subscription providing post-disaster survey imagery and optional AI damage classification/detection modules. The current system identifies properties in event zones, supplies high-resolution post-cat imagery, and describes FEMA five-tier classifications and detections such as structural roof damage, exposed deck, and tarps. Legal terms provide term-based access after qualifying wildfire, hurricane, or tornado events and permit ImpactResponse AI through Transactional Content API, AI Feature API, or licensed offline vector delivery. Survey capture is discretionary and weather/airspace dependent; no event is guaranteed. No exact flat scalar damage schema was found, so this Source has zero Features.

Open, event-specific satellite-derived building-damage point-vector releases for selected disaster areas. Current releases expose GDB/SHP full files with building-point geometry, observation date and sensor, confidence, field-validation status, damage class, settlement, event code and notes. Release pages pin pre/post imagery, publication/version and caveats. Coverage exists only where UNOSAT has produced an activation/release; it is not a global arbitrary-address lookup and findings are preliminary, visible-structural-damage observations rather than field inspections.

Open longitudinal building-point damage assessments issued under UNOSAT's explicit Comprehensive Damage Assessment name. The current Gaza release carries fourteen observation snapshots with sensor date, sensor code, confidence code and damage class, thirteen change/status fields, final grouped class, field validation, notes, administrative geography and event code. It is a separately named and materially different schema family, not a release instance of the standard 11-column product.

Commercial, non-contributory Elements product that automatically analyzes post-disaster Gray Sky imagery and returns event-scoped, property/building-attributed damage records together with available pre-catastrophe attributes. The separate Damage API offers coverage, event, extract, tile, count, and PDF-report services; official documentation says assessments are generally generated within 24 hours after Gray Sky imagery publication. Exact outputs include post-catastrophe collection/event, capture date, image id, camera technology, GSD, orientation source, model version, roof debris/missing-material/structural-damage/tarp percentages, solar-panel and water-heater damage detections, and approximate FEMA classification. Availability is limited to properties inside qualifying post-disaster Gray Sky collections; it is not a causation opinion or a claim-specific commissioned report.
