NEW ORLEANS — This week, the National Geodetic Survey began collecting damage assessment images after historic flooding in the state. These before and after images show the effects of the flooding from an aerial view.

Abbeville, Denham Springs, and Port Vincent are specific areas identified by FEMA and the National Weather Service as areas which received the most damage.

Before images are provided by Mapbox, Digital Globe, and OpenStreeMap; “After” images were captured by NOAA’s National Geodetic Survey in the aftermath of the historically heavy rainfall.

A team of NOAA aviators captured the images using a specialized remote-sensing cameras aboard NOAA’s King Air aircraft.

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.
