- Search method
- Enumerate both language listings and classify every native package ID by purpose. Resolve derived/baseline members against the 79-item 5 September listing and retain the seven queued image additions. Follow provider citations as new leads. Include every event-specific product and historical reference explicitly supplied with it. No language exclusion. Preserve all AOIs, dates, versions, corrections and access states; queue independently published off-platform resources for their own run. 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-20260906-022.
- Criteria
All languages and cloud levels. Spatial searches WGS84 [84.3976, 27.732, 85.5508, 28.35], 2026-06-27T00:00:00Z through 2026-09-06T22:33:49Z. Event releases retain their supplied historical references.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- Event products: source-defined event release and historical references; spatial queries WGS84 [84.3976, 27.732, 85.5508, 28.35] from 2026-06-27 to frozen run start.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: event asset listings.
- Stopping rule
- Exhaust all results and explicit product/metadata pagination for this declared interface; record unavailable or capped retrieval as such.
- Result
79 event asset listings. 1 discovery records; 79 per-run distinct asset URLs. Automated screening, with new candidates under review and known identities retained. No bulk archive body downloads. Original Chinese titles and available English provider titles retained. Existing quarantined malformed comparison archive remains excluded from usable-asset promotion.
