NOAA's National Geodetic Survey is the U.S. Government source for precise latitude, longitude, and elevation measurements. The NOAA fleet of ships and aircraft is operated, managed, and maintained by the NOAA Office of Marine and Aviation Operations, which includes commissioned officers of the NOAA Corps and civilian wage mariners.

From Aug. 3-5, the National Geodetic Survey (NGS) collected aerial damage assessment images of areas affected by Tropical Storm Isaias. Imagery was collected in specific areas identified by NOAA in coordination with the U.S. Coast Guard. 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 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.
