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

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.

Marconi Beach video camera 2 dark image
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.
