FEMA's Flooding Incident Journal provides relevant spatial decision-making support for FEMA leadership and a view into federal information available to the general public. This website is a part of the FEMA GeoPlatform.Individual applications shown in this journal are linked to at the bottom of each section.Any modeled damage assessments are based on flood depth grids, then verified with satellite imagery. Depth grids can be Observed (data from river, coastal, tide gauges), or Forecasted (created from Advanced Hydrologic Prediction Service, AHPS, forecasts). Remote Sensing contains flood extents and other data from NASA and Copernicus.
