The Digital Shoreline Analysis System (DSAS) version 6 is a standalone application that calculates shoreline or boundary change over time. The GIS of a user’s choice is used to prepare the data for DSAS. Like previous versions, DSAS v.6 enables a user to calculate rate-of-change statistics from multiple historical shoreline positions.

DSAS generates transects that are cast perpendicular to the reference baseline to intersect shorelines at a user-specified spacing alongshore.

USGS Coastal and Marine Field Operations

To conduct the science needed to understand coastal and marine geohazards, support habitat and resource management, and monitor how these environments change over time, the USGS Coastal and Marine Hazards and Resources Program relies on engineering, mechanical, and electronics expertise for field operations along the coast, in the nearshore environment, and in the d

Flyover of the U.S. Coastline

Our Nation’s coastlines are almost 100,000 miles long. These extensive coastal areas stretch from Maine’s Atlantic shores in the northeast, south along the shores of the Gulf of Mexico and insular areas in the Caribbean.

Two video cameras are mounted on a bluff above Marconi Beach, Cape Cod National Seashore, Wellfleet, MA. Every half hour, the video cameras collect imagery for 10 minutes. This is the “dark” image, the darkest pixel values throughout the video, useful for tracking sediment plumes, tracking floating debris, and filtering out breaking waves.
