[NOAA] Last week, the National Geodetic Survey (NGS) began collecting U.S. aerial damage assessment images for Hurricane Dorian. Imagery is being collected in specific areas identified by NOAA in coordination with FEMA and other state and federal partners. Collected images are available to view online via the NGS aerial imagery viewer.

NOAA’s aerial imagery aids safe navigation and captures damage to coastal areas caused by a storm. Aerial imagery is a crucial tool to determine the extent of the damage inflicted by flooding, and to compare baseline coastal areas to assess the damage to major ports and waterways, coastlines, critical infrastructure, and coastal communities. This imagery provides a cost-effective way to better understand the damage sustained to both property and the environment.

The team of NOAA aviators and sensor operators are capturing the images using specialized remote-sensing cameras aboard NOAA Office of Marine and Aviation Operations’ King Air aircraft flying above the area at an altitude between 500 and 1500 meters (about 1,600 to 5,000 feet).
View NOAA Emergency Response Imagery collected on the following days:
September 4, 2019: North Key Largo, Florida, to Hollywood, Florida.
September 5, 2019: Fort Lauderdale, Florida to just south of Savannah, Georgia.
September 7, 2019: Bald Head Island, North Carolina to Norfolk, Virginia
