India Urban Flood Exposure Evidence (IUFEE) v1.2
Year: 2026
Type: dataset
Abstract: IUFEE is a 100 m multi-source evidence database for 91 Indian functional urban areas. It links positive 2015 to 2020 GHSL building surface change (400.536 km2 over 1,259,886 cells) with seven return period GloFAS modelled fluvial depth layers, and preserves WSF 2019 documented and undocumented endpoint support, WSF Evolution historic detection, and paired GLAD 2015/2020 land cover classes.Version 1.3 adds the revision analysis code and derived results of a controlled comparison between a joint settlement overlay (J) and multiplication of its marginal fractions (F), with the archived product convention (A) as reference, holding source maps, registration, change weights, hazard depths and target cells fixed. The revision archive contains the analysis scripts, pooled and city depth components, the exact signed decomposition of the representation effect, paired GLAD class composition and retention, sensitivity alternatives for weights, thresholds, hazard summaries and quality flags, review queue coverage, the selected source review cells, and per-cell joint and marginal support contributions where included. The complete package, including the full per-cell support tables, is also available at the linked GitHub release. Version 1.2 files are retained unchanged.Licensing: the IUFEE database and derived data are released under CC BY 4.0; the analysis code is released under the MIT licence as stated in its README. Parent products (GHSL, WSF, GLAD, GloFAS) remain with their providers under their own terms and are not redistributed. Official map geometry is not redistributed.
