Hurricane Maria NOAA Imagery
February 15, 2018
From September 22 - 26, 2017, the National Geodetic Survey (NGS) collected damage assessment imagery in the aftermath of Hurricane Maria. The aerial imagery was collected in specific areas identified by FEMA and the National Weather Service. You can access all of the images collected online.

Forecasted Flood Depth Grids – Hurricane Irma
February 15, 2018
Forecasted flood depth grids were generated for Hurricane Irma using the National Weather Service's (NWS) Advanced Hydrologic Prediction Service (AHPS) forecasted water levels. These depth grids allowed for pre-event planning and early estimated hazard exposure counts.

Puerto Rico & USVI Building Outlines
February 14, 2018
Geospatial scientists at Oak Ridge National Laboratory have developed a novel method to quickly gather building structure datasets that support emergency response teams assessing properties damaged by Hurricanes Harvey, Irma and Maria. By coupling deep learning with high-performance computing, ORNL collected and extracted building outlines and roadways from high-resolution satellite and aerial images.
