The data shown here in a grayscale overlay represent the change in the component of the radar scattering that is attributable to leafy vegetation, with lighter shading representing greater changes than darker shading. The blue outline delineates the boundary of the total burned zone as determined by an independent survey conducted by the U.S. Forest Service.  The radar data were collected by NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar system on February 27 and September 18, 2009 while most of the damage from the Station Fire occurred between August 26 and September 4, 2009. || ",
