- Aim
- Inventory the live analytical layers and tables behind the UNOSAT event map.
- Source and interface
- UNITAR/UNOSAT — Public ArcGIS REST event service
- Search method
- GET the known official UNOSAT FL20260826NPL MapServer with f=pjson; enumerate every layer/table metadata endpoint. For queryable feature/table layers retrieve returnCountOnly=true and where=1=1. Preserve layer identity, source class, CRS, extent, fields, capabilities and counts. This run inventories the complete service structure; it does not export every geometry. Link to UNOSAT public product 4256 and existing analytical products. Stop after all listed layers/tables and metadata responses are accounted for. Actual request URLs and bodies, including pagination and endpoint recovery, are in search-reports/2026-09-07-remote-sensing-queries.json under RUN-20260906-018.
- Criteria
All languages and cloud levels. Spatial searches WGS84 [84.3976, 27.732, 85.5508, 28.35], 2026-06-27T00:00:00Z through 2026-09-06T22:31:19Z. Event releases retain their supplied historical references.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- Event products: source-defined event release and historical references; spatial queries WGS84 [84.3976, 27.732, 85.5508, 28.35] from 2026-06-27 to frozen run start.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: leaf analytical-service layers.
- Stopping rule
- Exhaust all results and explicit product/metadata pagination for this declared interface; record unavailable or capped retrieval as such.
- Result
46 leaf analytical-service layers. 1 discovery records; 50 per-run distinct asset URLs. Automated screening, with new candidates under review and known identities retained. The known MapServer returned a JSON error; current public web-map configuration will be consulted to determine whether the service route changed. Recovery: old UNOSAT_Analysis endpoint returned ArcGIS JSON error500. Official current Experience configuration and Nepal web map identify UNOSAT_Analysis_V2 and three additional analytical services. Unrelated template data sources not treated as Nepal products. One timed-out Copernicus layer40 request succeeded on a bounded retry; original failure retained in queries and resolved_failures.json.
