NOAA’s National Geodetic Survey (NGS) has collected 2,000 images of Louisiana catastrophic flood damage from August 2016.
Many rivers and waterways, particularly the Amite and Comite rivers, reached record levels, and rainfall exceeded 20 inches (510 mm) in multiple parishes. 13 deaths have been reported as a result and a state of emergency was declared.
The imagery was acquired by the NOAA Remote Sensing Division to support NOAA national security and emergency response requirements. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne digital imagery. Individual images have been combined into a larger mosaic and tiled for distribution. The approximate ground sample distance (GSD) for each pixel is 50 cm / zoom level 18. The images are available here.
