- Aim
- Recover dated satellite-flood geometries and distinguish them from alert and event envelopes.
- Source and interface
- GDACS — Public event API
- Search method
- Query event type FL and event ID 1104124 using the current documented API; enumerate episodes, dated observation records and source links, including pre-event observations. 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-20260906-030.
- Criteria
All languages and cloud levels. Spatial searches WGS84 [84.3976, 27.732, 85.5508, 28.35], 2026-06-27T00:00:00Z through 2026-09-06T22:39:46Z. Event releases retain their supplied historical references.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- Event products: source-defined event release and historical references; spatial queries WGS84 [84.3976, 27.732, 85.5508, 28.35] from 2026-06-27 to frozen run start.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: satellite observation/polygon-part attribute rows.
- Stopping rule
- Exhaust all results and explicit product/metadata pagination for this declared interface; record unavailable or capped retrieval as such.
- Result
236 satellite observation/polygon-part attribute rows. 1 discovery records; 7 per-run distinct asset URLs. Automated screening, with new candidates under review and known identities retained. Episode1 metadata succeeded using the documented endpoint on retry; original timeout preserved in request history. JRC satellite endpoint discovered in official GDACS report script. Read-only attribute query and object-ID cross-check; no shape-area field interpreted as hectares and no data-processing jobs run.
