Source and interface
Copernicus GFM/EODC — GFM STAC collection
Search method
Use the collection's advertised item-search interface with the common event bbox and time window. Paginate all items and list every advertised asset; preserve parent Sentinel-1 identifiers and temporal intervals. Exhaust the declared result set and all exposed pagination; retain original records and metadata. A provider limit or failed retrieval is a partial outcome, never a zero-result or complete run. Actual request URLs and bodies, including pagination and endpoint recovery, are in search-reports/2026-09-07-remote-sensing-queries.json under RUN-20260906-027.
Criteria
All languages and cloud levels. Spatial searchesWGS84 [84.3976, 27.732, 85.5508, 28.35], 2026-06-27T00:00:00Z through 2026-09-06T22:37:51Z. Event releases retain their supplied historical references.
Coverage
Event products: source-defined event release and historical references; spatial queries WGS84 [84.3976, 27.732, 85.5508, 28.35] from 2026-06-27 to frozen run start. Baselines retain stated source epochs. Native unit: STAC items.
Stopping rule
Exhaust all results and explicit product/metadata pagination for this declared interface; record unavailable or capped retrieval as such.
Result

101 STAC items. 1 discovery records; 1208 per-run distinct asset URLs. Automated screening, with new candidates under review and known identities retained.
