This is an example of a lidar image created from the “point cloud” that shows objects’ reflectivity near the Santa Cruz Beach Boardwalk and the mouth of the San Lorenzo River.

San Clemente Dam was a 106-foot-high concrete arch dam that was located approximately 18.5 miles from the Pacific Ocean on the Carmel River.

A digital still image can be overlaid onto the lidar “point cloud” data to give it a realistic 3D look.

PCMSC scientists maneuver the camera sled for deployment off R/V Parke Snavely in Monterey Bay. They will navigate the camera sled just above the seafloor to get a close-up view. Video, photographs, and real-time observations of seafloor geology and biological cover help develop and verify the maps created from sonar data.

Antonio Espejo Hermosa uses a handheld computer and GPS equipment to record beach topography data near Sunset State Beach in Santa Cruz.

USGS scientist Alex Snyder gathers topographic data by walking beach transects northwest of Moss Landing to help researchers understand how Monterey Bay will respond to changing environmental conditions.

Gathering this type of information helps USGS scientists to document the changes in beach and nearshore morphology (or form and structure), caused by seasonal variations and storms.
