On September 24, 2009 we did an oblique helicopter survey of the SAF from the southern end of the Carrizo Plain to Choice Valley and back at an altitude of 500 ft AGL nominal. On the northbound leg we shot SW and on the southbound leg we shot NE. Simultaneous video of the SAF was also obtained. In all 1454 color digital pictures were taken, each containing GPS information in the EXIF. Aircraft rental cost $2146. Long axis of the images was along track, i.e., parallel with the SAF.
