Big Sur Landslide, July 7, 2017

Detailed Description

USGS scientists continue to monitor the slide by collecting imagery every couple of weeks, weather permitting. Pilot Bob Van Wagenen, contracted through the Department of the Interior’s Office of Aviation Services, takes air photos for Jon Warrick’s Big Sur Landslide team, flying out of the Watsonville Municipal Airport in a Cessna 182R. He uses a camera-plus-GPS system designed by USGS ocean engineer Gerry Hatcher to record the precise time and geographic location of each photo—information that speeds processing and increases the accuracy of the maps derived from the photos.
