Abstract:	The imagery posted on this site was acquired following Nashville Tornado in March 2020. The aerial photography missions were conducted by the NOAA Remote Sensing Division. The images were acquired from an altitude of 2500 to 5000 feet, using a Trimble Digital Sensor System (DSS).
Purpose:	This imagery was acquired by the NOAA Remote Sensing Division to support NOAA national security and emergency response requirements. This rapid response product was generated for use by emergency managers for visual analysis of damage in the area. It is not intended for mapping, charting or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne digital imagery.
Supplemental Information:	The ground sample distance (GSD) for each pixel is 15 cm. In an effort to acquire imagery in a timely manner after the event, clouds may be present in the imagery. Be advised that the Bounding Coordinates reflect the extents of the images acquired for this event and do not imply full image coverage of the area.
