Derived Flood Projection Layers and Affected Buildings for Metro Manila

geographies-4214028 This dataset contains derived geospatial outputs from the study on relative sea level rise (RSL) projections and permanent inundation risks in Metro Manila due to climate change and land subsidence. Projections are based on PSMSL tide gauge records, IPCC AR6 SSP scenarios, satellite altimetry, and vertical land motion (VLM) calibrations. Spatial analyses use OpenStreetMap (OSM) data for impact assessment on buildings and infrastructure. The data support Figures and results in the manuscript, including projected flood extents (permanent inundation) for 2100 and 2150 under different SSPs. Key Files: floods_2100.gpkg: Vector/GeoPackage layer of projected permanent inundation areas for 2100 (CRS: EPSG:32651). floods_2150.gpkg: Same for 2150. buildings_flooded_2100.gpkg: Filtered OSM buildings intersecting 2100 inundation (CRS: EPSG:32651). buildings_flooded_2150.gpkg: Same for 2150. Usage: Open in QGIS (Add Vector Layer) or Python (geopandas). Style binary field (1=flooded). All base inputs public (PSMSL, IPCC AR6, OSM).
