Search method
Query Planetary Computer STAC for collections 'sentinel-1-rtc' and 'sentinel-2-l2a' intersecting WGS84 bbox [84.3976, 27.7320, 85.5508, 28.3500] for dates 2026-08-15 to 2026-09-02. Enumerate exact scene identifiers, orbits, polarizations, and band assets.
Criteria
CriterionSentinel-1 IW GRD RTC (VV, VH) and Sentinel-2 L2A (10-20m multispectral + SCL). Corridors across Rasuwa and Nuwakot.
Coverage
Complete calibrated radar backscatter and cloud-filtered multispectral surface reflectance scenes supporting all derived change analyses.
Stopping rule
Exhaust all valid STAC items overlapping the spatial bounding box across the 18-day window.
Result

2 primary satellite observation collections recovered across 4 assets: multi-temporal Sentinel-1 RTC radar backscatter scenes and cloud-screened Sentinel-2 L2A multispectral granules.
