Completed catalogue assessment
- Eligibility decision
- Include · Included Resource
- Assessment date
- 28 September 2026
- Decision reason
- The original UNOSAT/HDX barrier-lake product refers to Cartosat-3 imagery of 28 August and interpreted lake areas. Its GDB download is the same shared event geodatabase as other products, not a separate lake-only shapefile. Retain the product identity and original preliminary interpretation without inferring depth, volume, stability or field validation.

Method and provenance
- Production method
- UNOSAT identified and measured two newly formed barrier lakes in CARTOSAT-3 imagery acquired 28 August 2026 following the ice-rock avalanche.
- Provenance
- Produced by UNOSAT under code FL20260826NPL and published through HDX. Relevant point and polygon layers occur in the shared multi-product event File Geodatabase.
- Validation
- Not Validated
- Uncertainty
- The assessment is preliminary and not field validated. Lake outlines and areas depend on the characteristics and interpretation of the 28 August CARTOSAT-3 image.
- Limitations
- The record documents two detected lakes at one post-event observation date; it does not by itself establish subsequent lake evolution, stability, or breach probability.
