Gerry Hatcher and Camera System

USGS ocean engineer Gerry Hatcher with the camera system he helped create for recording the precise time and geographic location of each air photo it takes. The system is mounted in the cargo compartment of a Cessna 182R airplane and takes photos through a window cut into a removable cargo door (right). USGS scientists analyze the photos with “structure-from-motion” software to identify and measure coastal change.
