Eligibility decision
Include · Included Data
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.
