Detailed Description

USGS photographs taken from a contracted small airplane are used to build three-dimensional representations of the hillslopes of Big Sur, California, as shown here for the Mud Creek landslide site in 2017.  Blue symbols show the locations of individual photos obtained on the flight, and the gray area shows the hillslope landscape created from the photos using Structure-from-Motion (SfM) photogrammetry.
