Polarimetric image of Croatan National Forest, NC acquired by a UAVSAR overflight on Sep 23, 2018 . 
Collection of UAVSAR imagery will help to clarify where barrier islands and the coastline have been impacted. Furthermore, rapid acquisition of UAVSAR imagery of damaged homes and infrastructure provides higher spatial resolution details to complement “damage proxy maps” and other change detection approaches applied from routinely collected imagery or special collections from international partners.  NOAA and other agencies will fly complementary aerial photography to help document change for correlation to signals obtained at the wavelengths of UAVSAR (L-Band, polarized) and other...

UAVSAR image of Montecito debris flows.
Extreme winter rains in January 2018 following the Thomas Fire in Ventura and Santa Barbara Counties caused severe debris flows, destroying 73 homes and damaging over 160 structures in the town on Montecito, just east of Santa Barbara. NASA UAVSAR airborne radar platform detected changes caused by the debris flows between two images acquired on November 2, 2017 and February 5, 2018. An enhanced image pair (top left) show disturbed areas in orange. The two image pairs can’t be matched and decorrelate in areas of severe surface disruption from the fire scar and debris flows (top right). In the...

PolSAR Mosaic Image
UAVSAR aboard the NASA502 aircraft imaged Napa County, California on October 16 to observe areas affected by several wildfires that started on October 8 and burned thousands of buildings as well as vineyards and forests. PolSAR mosaick of HH, HV, VV polarization overlay images. The fire perimeters (red) are from the USGS Geospatial Multi-Agency Coordination website as of October 17.   The fires from north to south are: Pocket, Tubbs, Nunn, and Atlas respectively.....
