Parcel flood inundation history
Which historical riverine, pluvial, coastal, or storm-surge inundation events intersected this parcel, and what extent, depth, or severity was attributed here?
The data that answers it
Ranked by fit · best firstICEYE Flood Insights supplies licensed global event extent plus post-peak maximum extent and modeled depth at building level, with frequent dated updates through a standing API, hub, download, or partner integration; outputs remain observed or model-assisted event evidence.
For a buyer-selected AOI and time range, the standing GFM API and archive provide 20 m Sentinel-1-derived observed-flood-extent classes with sensing time and semantic product version. Parcel intersection establishes covered-scene extent, not depth, mechanism, building entry, or direct ground observation.
The standing commercial CONUS product supplies daily event footprints, vendor-described severity, a maximum-observed summary, and daily time series as geospatial files. Parcel intersection does not prove building entry or damage.
JBA's standing event-response catalogue supplies selected major-event footprint files through its client portal or documented request channel; covered model-derived extent and depth substantiate parcel intersection when event, method, model basis, and file vintage are retained.
Public STN services retrieve event-linked surveyed high-water marks by event, site, filter, or buyer-selected location. A mark within the parcel supplies event, coordinates, dates, elevation or height, datum, environment, and quality as point severity evidence, not a continuous footprint.
